consider a student loan of $15000 at a fixed APR of 12 % for 20 years

Answers

Answer 1

Therefore, the monthly payment for a student loan of $15,000 at a fixed APR of 12% for 20 years is $144.36.

What is interest?

Interest is the cost of borrowing money or the return on investing money. When you borrow money, you usually have to pay back more than you borrowed, and the additional amount you pay is the interest. The interest rate is expressed as a percentage of the borrowed amount, and it can vary depending on factors such as the borrower's credit score, the term of the loan, and the lender's policies.

Given by the question.

Assuming the loan has a fixed interest rate of 12% per annum, the amount of interest charged each year will be:

12% of $15,000 = $1,800

The total interest charged over 20 years will be:

$1,800 x 20 = $36,000

The total amount to be repaid (principal + interest) will be:

$15,000 + $36,000 = $51,000

If the loan is being repaid in equal monthly installments over the 20-year term, the monthly payment can be calculated using the following formula:

M = P * (r[tex](1+r)^{n}[/tex]) / ([tex](1+r)^{n}[/tex]- 1)

Where:

M = Monthly payment

P = Principal amount (in this case, $15,000)

r = Monthly interest rate (12% per annum / 12 months = 1% per month)

n = Total number of payments (20 years x 12 months per year = 240)

Plugging in the values:

M = $15,000 * (0.01[tex](1+0.01)^{240}[/tex]) / ([tex](1+0.01)^{240}[/tex] - 1)

M = $144.36

Step-by-step explanation:

a homogeneous wire is bent into the shape shown. determine the x coordinate of its centroid by direct integration. express your answer in terms of a.

Answers

The x coordinate of the centroid of the wire with y=kx^(3/2) and x and y intercept a is 0.546a. The y coordinate is 8a/5.

To find the centroid of the wire, we need to find the area and first moments of the wire, which are given by:

Area, A = ∫y dx, where x ranges from -a to a

First moment with respect to x, Mx = ∫xy dx, where x ranges from -a to a

Then the x coordinate of the centroid is given by:

xc = Mx / A

We can start by finding the area:

A = ∫y dx = ∫kx^(3/2) dx = (2/5)kx^(5/2) + C

At x = a, y = 0, so C = - (2/5)ka^(5/2)

At x = -a, y = 0, so A = 2(2/5)ka^(5/2) = (4/5)ka^(5/2)

Now we need to find the first moment with respect to x:

Mx = ∫xy dx = ∫kx^(5/2) dx = (2/7)kx^(7/2) + C'

At x = a, y = 0, so C' = - (2/7)ka^(7/2)

At x = -a, y = 0, so Mx = 0

Therefore, the x coordinate of the centroid is:

xc = Mx / A = 0 / [(4/5)ka^(5/2)] = 0

This means that the centroid lies on the y-axis. To find its y coordinate, we can use the formula:

yc = ∫x dy / A = ∫x (dy/dx) dx / A

Using the equation y = kx^(3/2), we can find dy/dx:

dy/dx = (3/2)kx^(1/2)

Substituting this into the formula for yc and simplifying, we get:

yc = (4/5)ka^(5/2) / (5/8)ka^(5/2) = (8/5)a

Therefore, the coordinates of the centroid are (0, 8/5 a), and the y coordinate is (8/5)a.

To find the x coordinate of the centroid, we need to use the formula:

xc = (1/A) ∫x y dx

We already found the expression for the area A, so we just need to evaluate the integral:

xc = (1/A) ∫x y dx = (1/A) ∫x kx^(3/2) dx

Integrating this by substitution with u = x^(1/2), we get:

xc = (2/5a^(5/2)) ∫u^4 du = (2/5a^(5/2)) (u^5/5) + C

where C is a constant of integration.

At x = a, y = 0, so u = a^(1/2) and C = -(2/25)a^(5/2).

At x = -a, y = 0, so the contribution to the integral is zero.

Therefore, the x coordinate of the centroid is:

xc = (2/5a^(5/2)) (u^5/5) - (2/25a^(5/2)) = (2/25)a(5√2 - 1)

Plugging in a = 1, we get:

xc = 0.546a

So the x coordinate of the centroid is 0.546 times the x and y intercept value a.

you have 96 houses.

when you sell 1/4 of the houses, (= 96 × 1/4 = 24) you have 3/4 of the houses left (= 96 × 3/4 = 96 - 96 × 1/4 = 72).

so, what you have left are 3/4 of the houses. NOT 1/6.

3/4 is NOT 1/6.

1/6 of the original 96 houses is

96 × 1/6 = 96/6 = 16 houses

but if 72 (the remaining houses after the first sell of 1/4) is supposed to be 1/6, then the total number of houses at the beginning would have been

72 × 6 = 432 houses. NOT 96.

Bria is a customer who would like to display her collection of soap carvings on top of her bookcase. The collection needs an area of 300 square inches. What should b equal for the top of the bookcase to have the correct area? Round your answer to the nearest tenth of an inch. I need help D:
Please !!!!​

Answers

Therefore, the width of the top of the bookcase should be 12 inches to have an area of 300 square inches.

What is area?

In mathematics, area is a measure of the size of a two-dimensional region or surface. It is usually expressed in square units, such as square meters or square inches. The area of a flat surface is the amount of space inside its boundary or perimeter. The formula for calculating the area of various shapes can vary, but it typically involves measuring the length and width of the shape and using a mathematical formula to find the product of these two dimensions. For example, the area of a rectangle can be found by multiplying its length by its width, while the area of a circle can be found by multiplying pi (approximately 3.14) by the square of its radius.

Here,

Let's assume that the top of the bookcase is a rectangle with length (L) and width (b), so its area is given by the formula:

A = L * b

We are told that Bria's soap carving collection needs an area of 300 square inches. Therefore, we can write:

300 = L * b

Solving for b, we can divide both sides by L:

b = 300 / L

We don't know the value of L, but we can assume that it's some value that Bria has already determined. We just need to find the corresponding value of b that satisfies the equation.

For example, if Bria decides that the length of the top of the bookcase should be 20 inches, we can substitute L = 20 into the equation above:

b = 300 / 20 = 15 inches

So in this case, the width of the top of the bookcase should be 15 inches in order to have an area of 300 square inches.

If Bria decides on a different value of L, we can plug it into the equation to find the corresponding value of b. For instance, if she decides that L should be 25 inches:

b = 300 / 25 = 12 inches

Let X1, X2, ..., Xn denote n independent and identically distributed Bernoulli random vari- ables s.t. P(X; = 1) = p and P(Xi = 0) = 1 – p. for each i = 1, 2, ..., n. Show that __, Xi is sufficient for p by using the factorization criterion given in Theorem 9.4. THEOREM 9.4 Let U be a statistic based on the random sample Yı, Y2, ..., Yn. Then U is a sufficient statistic for the estimation of a parameter 0 if and only if the likelihood L(0) = L(y1, y2, ..., yn 10) can be factored into two nonnegative functions, L(y1, y2, ..., yn (0) = g(u,0) x h(yı, y2, ..., yn) where g(u,0) is a function only of u and 0 and h(y1, y2, ..., yn) is not a function of o.

Answers

The likelihood function can be factored using Theorem 9.4 as L(p) = L(X₁, X₂, ..., Xn | p) = g(Σⁿᵢ=1Xᵢ, p) * h(X₁, X₂, ..., Xn), where g(Σⁿᵢ=1Xᵢ, p) = p^Σⁿᵢ=1Xᵢ (1-p)^(n-Σⁿᵢ=1Xᵢ) and h(X₁, X₂, ..., Xn) = 1. This satisfies the factorization criterion, and thus, Σⁿᵢ=1Xᵢ is a sufficient statistic for p.

To show that Σⁿᵢ=1Xᵢ is sufficient for p, we need to show that the likelihood function can be factored using Theorem 9.4 as:

L(p) = L(X₁, X₂, ..., Xn | p) = g(Σⁿᵢ=1Xᵢ, p) * h(X₁, X₂, ..., Xn)

where g(Σⁿᵢ=1Xᵢ, p) is a function only of Σⁿᵢ=1Xᵢ and p, and h(X₁, X₂, ..., Xn) is not a function of p.

First, we can write the joint probability mass function of X₁, X₂, ..., Xn as:

P(X₁ = x₁, X₂ = x₂, ..., Xn = x_n) = p^Σⁿᵢ=1xᵢ (1-p)^Σⁿᵢ=1(1-xᵢ)

Taking the product of these probabilities for all i, we get:

L(p) = L(X₁, X₂, ..., Xn | p) = Πⁿᵢ=1P(Xᵢ = xᵢ) = p^Σⁿᵢ=1Xᵢ (1-p)^Σⁿᵢ=1(1-Xᵢ)

Using the factorization criterion given in Theorem 9.4, we need to find functions g(u, p) and h(X₁, X₂, ..., Xn) such that:

L(p) = L(X₁, X₂, ..., Xn | p) = g(Σⁿᵢ=1Xᵢ, p) * h(X₁, X₂, ..., Xn)

Let's take g(u, p) = pᵘ(1-p)⁽ⁿ⁻ᵘ⁾, which only depends on u and p. Then:

L(p) = L(X₁, X₂, ..., Xn | p) = g(Σⁿᵢ=1Xᵢ, p) * h(X₁, X₂, ..., Xn)

= p^Σⁿᵢ=1Xᵢ (1-p)^Σⁿᵢ=1(1-Xᵢ) * h(X₁, X₂, ..., Xn)

We can see that the term Σⁿᵢ=1Xᵢ appears in the exponent of p, and Σⁿᵢ=1(1-Xᵢ) appears in the exponent of (1-p). Therefore, we can write:

L(p) = L(X₁, X₂, ..., Xn | p) = [p^Σⁿᵢ=1Xᵢ (1-p)^Σⁿᵢ=1(1-Xᵢ)] * [1]

where the second factor is a constant function of p. This satisfies the factorization criterion, with g(u, p) = pᵘ(1-p⁽ⁿ⁻ᵘ⁾ and h(X₁, X₂, ..., Xn) = 1.

Therefore, we have shown that Σⁿᵢ=1Xᵢ is a sufficient statistic for p.

Step-by-step explanation:

Answer:

[tex]2730[/tex]

Step-by-step explanation:

We can solve this problem without using any complex formulas, though there is a formula for solving such problems

Out of the 15 participants, only one participant can be in first place but this can be any one of the participants

So choice for first place = 15 participants

Once a participant has won in the first place, there are 14 remaining participants who can come second place

For third place there are only 13 participants who can make it

The total number of ways in which top three participants can be arranged is

15 x 14 x 13 = 2730 ways

The formula is

[tex]P(n, r ) = \dfrac{n!}{(n-r)!}[/tex]

where n is the population to be considered; here n = 15

r = number of items to be considered ; here r = 3

[tex]P(n, r)[/tex] sometimes written as [tex]_nP_r[/tex] represents the number of subsets  r that can be taken from a larger set  n when the order of the subset matters.

using the formula we get

Suppose that 13% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?

Answers

Step-by-step explanation:

If 13% of people own dogs, then the probability that a randomly selected person owns a dog is 0.13. Assuming that the ownership of dogs is independent between people, the probability that two randomly selected people both own a dog is equal to the product of their individual probabilities:

P(both own a dog) = P(1st person owns a dog) * P(2nd person owns a dog | 1st person owns a dog)

P(both own a dog) = 0.13 * 0.13

P(both own a dog) = 0.0169

Therefore, the probability that two people picked at random both own a dog is 0.0169 or approximately 1.69%.

What is Function?

Function is a rule that assigns  unique output value to each input value in  a set. The input values are typically represented by variable x, while the output values are represented by  variable y. A function can be thought of as machine that takes an input, processes it according to a specified rule, and produces output.

Functions have many applications in various fields of mathematics and science, like  calculus, linear algebra, and physics. They are also used in computer science and programming, where they are essential for data analysis, machine learning, and other applications.

a. In the linear function y=-9x + 55000, the coefficient of x (-9) represents the rate of change, which indicates how much the value of the car decreases for each mile driven. Specifically, for each mile driven, the value of the car decreases by $9. The initial value of the function is the y-intercept, which is 55000. This represents the value of the car when it has not yet been driven any miles.

b. To find when the car will be valued at $35,002, we can substitute y=35,002 into the linear equation and solve for x:

y=-9x + 55000

35,002=-9x + 55000

-9x = -14998

x = 1666.44

Therefore, the car will be valued at $35,002 when it has been driven approximately 1666 miles.

Determine the slope of the given line. The line y = 1/2x + 4 is in slope-intercept form (y = mx + b), where the slope is m = 1/2.

Find the negative reciprocal of the slope from step 1 to obtain the slope of the perpendicular line. The negative reciprocal of 1/2 is -2, so the slope of the perpendicular line is -2.

Use the point-slope form of a line (y - y1 = m(x - x1)) and plug in the slope from step 2 and the point (-8, 3) to find the equation of the perpendicular line.

y - 3 = -2(x + 8)

Simplifying this equation gives:

y = -2x - 13

Therefore, the equation of the perpendicular line passing through (-8, 3) is y = -2x - 13.

For a certain​ automobile, M(x)=-.015x^2+1.32x-7.4​,30= ​, represents the miles per gallon obtained at a speed of x miles per hour.
​(a) Find the absolute maximum miles per gallon and the speed at which it occurs.
​(b) Find the absolute minimum miles per gallon and the speed at which it occurs.

Answers

Answer: (a) To find the absolute maximum miles per gallon, we need to find the maximum value of M(x). We can do this by finding the vertex of the parabola represented by M(x).

The x-coordinate of the vertex is given by:

x = -b / (2a)

where a = -0.015 and b = 1.32 in our case. Plugging in these values, we get:

x = -1.32 / (2(-0.015)) = 44

So the maximum miles per gallon occurs at a speed of 44 miles per hour.

To find the value of M(x) at this speed, we plug in x = 44:

M(44) = -0.015(44)^2 + 1.32(44) - 7.4 ≈ 32.36

Therefore, the absolute maximum miles per gallon is approximately 32.36, and it occurs at a speed of 44 miles per hour.

(b) To find the absolute minimum miles per gallon, we need to find the minimum value of M(x). We can do this by noting that the coefficient of the x^2 term is negative, which means that the parabola opens downward and has a maximum, so there is no absolute minimum.

We can also confirm this by finding the x-coordinate of the vertex, which we already calculated in part (a) to be x = 44. This means that the parabola has a minimum value of M(44), which we found to be approximately 32.36. However, this is not an absolute minimum, as there are values of M(x) that are smaller than 32.36 for other values of x. Therefore, there is no absolute minimum miles per gallon.

Step-by-step explanation:

h=p√m2+n find the value of h when p = 3, n=20 , m=6

Answers

Answer:

We can substitute the given values of p, m, and n into the formula for h:

h = p√(m^2 + n)

h = 3√(6^2 + 20)

h = 3√(36 + 20)

h = 3√56

We can simplify this by factoring 56 into its prime factors:

h = 3√(2^3 × 7)

h = 3 × √(2^2 × 7) × √2

h = 3 × 2√7

Therefore, when p = 3, n = 20, and m = 6, the value of h is 6√7 or approximately 13.42.

A student would have to score approximately 0.89 standard deviations above the mean to be in the top 12% and be publicly recognized.

How do we calculate?

we can use the empirical rule to estimate the number of standard deviations a student has to score above the mean to be in the top 12 percent, assuming it is a normal distribution

The empirical rule states that for a normal distribution:

Approximately 68% of the data falls within one standard deviation of the mean.Approximately 95% of the data falls within two standard deviations of the mean.Approximately 99.7% of the data falls within three standard deviations of the mean.

we will use the complement rule since our aim is to find the number of standard deviations a student has to score above the mean to be in the top 12%.

The complement of being in the top 12% is being in the bottom 88%.

From the empirical rule, we have that 68% of the data falls within one standard deviation of the mean.

Therefore, the remaining 32% (100% - 68%) falls outside one standard deviation of the mean.

Since we want to find the number of standard deviations a student has to score above the mean to be in the bottom 88%, we can assume that the remaining 32% is split evenly between the two tails of the distribution.      

Applying the z-score formula:

z = (x - μ) / σ

The z-score for a cumulative area of 0.44 is approximately -0.89  found by looking up the z-score corresponding to the cumulative area of 0.44 (half of 0.88) in a standard normal distribution table.

Diaz Nesamoney is a computer scientist who founded three successful software companies. Entrepreneurs tend to have a high ____
a. bounded optimization.
b. escalation of commitment.
c. risk propensity.
d. strategic maximization.
e. intuitive rationality

Answers

Diaz Nesamoney's experience as an entrepreneur demonstrates a high risk propensity, which is the tendency to take risks that have a potentially positive outcome.

In fact, entrepreneurs are required to be risk-takers as they typically have to invest time, resources, and capital into new ventures with uncertain outcomes. This risk-taking behavior is driven by an innate desire to create something new, whether it's a product, service, or business. However, it's not just risk-taking that characterizes the entrepreneurial mindset, but also a combination of other factors like creativity, determination, and strategic thinking.

Entrepreneurs are known for their strategic maximization skills, which involve the ability to assess opportunities and develop plans that leverage resources effectively to meet their objectives. Strategic thinking allows entrepreneurs to make difficult decisions with limited information, adapt to shifting market conditions, and identify opportunities where others see only obstacles. This kind of thinking requires intuition and creativity, which are key entrepreneurial traits. In addition, entrepreneurs are also known for their bounded optimization behaviors, which involve making decisions that are informed by limitations such as time, money, and available resources. This makes the best use of available resources to achieve the desired outcomes.

Furthermore, entrepreneurs often exhibit an escalation of commitment, which means that they continue to invest in a failing venture despite the costs associated with such a decision. They believe in their vision and goals so much that they're ready to take the risk, invest further resources, and make changes to the strategy until they succeed. This determination and belief inspire others to follow, work harder and go the extra mile. Overall, entrepreneurs are individuals with a range of attributes, including a high risk propensity, strategic thinking ability, intuition, creativity, and determination. These traits enable them to turn their unique ideas into successful businesses.

find the value of the derivative (if it exists) at

Answers

Answer:

The derivative does not exist at the extremum (-2, 0).

Step-by-step explanation:


Given function:

[tex]f(x)=(x+2)^{\frac{2}{3}}[/tex]

To differentiate the given function, use the chain rule and the power rule of differentiation.

[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Chain Rule of Differentiation}\\\\If $y=f(u)$ and $u=g(x)$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=\dfrac{\text{d}y}{\text{d}u}\times\dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}[/tex]

[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Power Rule of Differentiation}\\\\If $y=x^n$, then $\dfrac{\text{d}y}{\text{d}x}=nx^{n-1}$\\\end{minipage}}[/tex]

[tex]\begin{aligned}\textsf{Let}\;u &= x+2& \implies f(u) &= u^{\frac{2}{3}}\\\\\implies \dfrac{\text{d}u}{\text{d}{x}}&=1 &\implies \dfrac{\text{d}y}{\text{d}u}&=\dfrac{2}{3}u^{(\frac{2}{3}-1)}=\dfrac{2}{3}u^{-\frac{1}{3}}\end{aligned}[/tex]

Apply the chain rule:

[tex]\implies f'(x) = \dfrac{\text{d}y}{\text{d}{u}} \cdot \dfrac{\text{d}u}{\text{d}{x}}[/tex]

[tex]\implies f'(x) = \dfrac{2}{3}u^{-\frac{1}{3}} \cdot1[/tex]

[tex]\implies f'(x) = \dfrac{2}{3}u^{-\frac{1}{3}}[/tex]

Substitute back in u = x + 2:

[tex]\implies f'(x) = \dfrac{2}{3}(x+2)^{-\frac{1}{3}}[/tex]

[tex]\implies f'(x) = \dfrac{2}{3(x+2)^{\frac{1}{3}}}[/tex]

An extremum is a point where a function has a maximum or minimum value. From inspection of the given graph, the minimum point of the function is (-2, 0).

To determine the value of the derivative at (-2, 0), substitute x = -2 into the differentiated function.

[tex]\begin{aligned}\implies f'(-2) &= \dfrac{2}{3(-2+2)^{\frac{1}{3}}}\\\\ &= \dfrac{2}{3(0)^{\frac{1}{3}}}\\\\&=\dfrac{2}{0} \;\;\;\leftarrow \textsf{unde\:\!fined}\end{aligned}[/tex]

As the denominator of the differentiated function at x = -2 is zero, the value of the derivative at (-2, 0) is undefined.  Therefore, the derivative does not exist at the extremum (-2, 0).

An 8-year project is estimated to cost $448,000 and have no residual value. If the straight-line depreciation method is used and the average rate of return is 9%, determine the
average annual income.

Answers

Therefore , the solution of the given problem of average comes out to be the average yearly income is $67,200.

Explain average.

The exact number that constitutes the mean in a group with structure is its median value. In this instance, as opposed to being a typical measurement, the percentage ratio among the lowest and greatest 50% of the collection is a probability measurement. Different methods may be employed to determine the centre and mode of any odd or strange numbers.

Here,

The following formula is used to determine the project's yearly depreciation:

=> (Initial cost – Residual worth) / (Useful life) = Annual Depreciation

The project's useful life is 8 years, and since there is no residual worth, the annual depreciation is as follows:

=> Depreciation per year =  ($448,000 - $0) / 8 = $56,000

The annual average income is calculated as the original cost multiplied by the initial rate of return, divided by the number of years of useful life:

Average yearly revenue is calculated as follows:

=> (Annual depreciation + Average rate of return x Initial cost) / Useful life

When we change the numbers, we obtain:

=> ($56,000 + 0.09 x $448,000) / 8 = $67,200 annually is the average yearly income.

The average yearly income is therefore $67,200.

On the axes below, draw and label vectors to show the electric fields E1 and E2 and also indicate the resultant electric field E at the origin.

Answers

a. The magnitude and direction of the electric field E at the origin O due to the two charges is 2.29 × 10⁴ N/C.

b. The electric potential V at the origin is zero

a. To find the electric field at the origin, we need to consider the electric forces that each charge exerts on a positive test charge placed at that point. The magnitude of the electric field E at the origin is given by the formula:

E = k * |Q₁| / r₁² + k * |Q₂| / r₂²,

where k is Coulomb's constant, |Q₁| and |Q₂| are the magnitudes of the charges, and r₁ and r₂ are the distances from each charge to the origin.

In this case, Q₁ = − 1.6 × 10⁻⁶ C and Q₂ = + 9 × 10⁻⁶ C, so the magnitude of the electric field at the origin is:

E = k * |Q₁| / r₁² + k * |Q₂| / r₂²

= 9 × 10⁹ N·m²/C² * |− 1.6 × 10⁻⁶ C| / (4 m)² + 9 × 10⁹ N·m²/C² * |+ 9 × 10⁻⁶ C| / (3 m)²

= 2.29 × 10⁴ N/C.

b. To find the electric potential at the origin, we need to integrate the electric field from infinity to the point in question. The electric potential V at the origin is given by the formula:

V = − ∫ E · dr

where the integral is taken along any path from infinity to the origin. Since the electric field is conservative, the value of the integral does not depend on the path taken.

Therefore, we can choose a path that goes straight from infinity to the origin, and the integral simplifies to:

V = − ∫ E · dr = − E ∫ dr = − E x r,

where r is the distance from the origin to the point where the test charge is located. Since we are interested in the potential at the origin, we set r = 0 and obtain:

V = 0.

Therefore, the electric potential at the origin is zero, which means that the potential energy of a test charge placed at the origin is the same as the energy of a charge at infinity.
