The total amount payable at the end of the loan is Option 1: $369817.20 and Option 2: $233607.60.

APR, which stands for Annual Percentage Rate, refers to the yearly interest rate that is applied to loans. APR takes into account not just the interest rate but also any other expenditures or expenses related to the loan, including points or closing costs. APR offers a uniform approach to assess the costs and benefits of various lending solutions. Lenders are required by law to provide borrowers with the APR of a loan so they may make educated judgements about their borrowing alternatives.

The total payment for the loan is the monthly amount paid over the course of loan.

For option 1 the number of months are:

n = 30 (12) = 360

The total payable amount is:

$1027.27 (360) = $369817.20

For option 2 the number of months are:

n = 15 (12) = 180

The total payable amount is:

$1297.82 (180) = $233607.60

Hence, the total amount payable at the end of the loan is Option 1: $369817.20 and Option 2: $233607.60.

Answer: We are given that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C.

To find the probability of obtaining a reading between 0°C and 1.08°C, we need to calculate the z-scores for these values using the formula:

z = (x - mu) / sigma

where x is the value we are interested in, mu is the mean, and sigma is the standard deviation.

For x = 0°C, we have:

z1 = (0 - 0) / 1.00 = 0

For x = 1.08°C, we have:

z2 = (1.08 - 0) / 1.00 = 1.08

Using a standard normal table or a calculator, we can find the probability of obtaining a z-score between 0 and 1.08.

Using a standard normal table or a calculator, we find that the probability of obtaining a z-score between 0 and 1.08 is 0.3583.

Therefore, the probability of obtaining a reading between 0°C and 1.08°C is 0.3583, rounded to 4 decimal places.

Step-by-step explanation:

The value of n that yields the smallest S_n element having an order of at least 100 is 101.

To find the minimum value of n for which the set S_n contains an element with an order equal to or greater than 100, the formula S_n = n!/r!(n-r)! can be used. This formula calculates the number of permutations in a set with n elements, where r elements are chosen at a time. By substituting r=100 into the formula, it is determined that n must be at least 101 to contain an element with an order of 100 or greater. Therefore, the smallest value of n for which S_n contains an element with an order of 100 or greater is 101.

The above question is incomplete, I answer the question in general according to my knowledge:

Suppose that a and b are nonzero vectors that are not parallel and c is any vector in the plane determined by a and b. Give a geometric argument to show that c can be written as c=sa +tb for suitable scalars s and t. Then give an argument using components.

Answer: We know that the center of the ellipse is the midpoint of the line segment joining the foci. So, the center is ((15+3)/2, (-2-2)/2) = (9, -2).

The distance between the foci is 2c, where c is the distance between the center and each focus. So, 2c = 15 - 3 = 12, which means c = 6.

The distance between the center and each co-vertex is b. So, b = 10 - (-2) = 12.

The semi-major axis is a, which is the distance from the center to a vertex. Since we have the co-vertices, we can use the Pythagorean theorem to find a:

a^2 = b^2 - c^2

a^2 = 12^2 - 6^2

a^2 = 108

a = sqrt(108) = 6*sqrt(3)

Therefore, the equation of the ellipse is:

(x - 9)^2 / (6*sqrt(3))^2 + (y + 2)^2 / 12^2 = 1

Simplifying, we get:

(x - 9)^2 / 72 + (y + 2)^2 / 144 = 1

So, the equation of the ellipse is (x - 9)^2 / 72 + (y + 2)^2 / 144 = 1.

The equation for the tangent line to the curve y = f(x) that passes through the point (1,1) is y = (x + 1)/2. Using this equation, we can estimate the value of f(1.2) to be approximately 1.1.

To find the equation for the tangent line to the curve y = f(x) that passes through the point (1,1), we first need to find the derivative of y with respect to x, which is given by:

dy/dx = xy/2

Next, we can use the point-slope form of the equation of a line to write the equation for the tangent line:

y - 1 = (x - 1)(dy/dx at (1,1))

dy/dx at (1,1) = (1*1)/2 = 1/2

y - 1 = (x - 1)(1/2)

2y - 2 = x - 1

2y - x = 1

y = (x + 1)/2

Therefore, the equation for the tangent line to the curve y = f(x) that passes through the point (1,1) is y = (x + 1)/2 .

To estimate the value of f(1.2), we can use the equation of the tangent line we just found:

y =  (x + 1)/2

At x = 1.2, the value of y can be estimated by substituting x = 1.2 into the equation of the tangent line:

y = (1.2 + 1)/2

y = 2.2/2

y = 1.1

Therefore, using the equation of the tangent line, we can estimate the value of f(1.2) to be approximately 1.1.

Step-by-step explanation:

If the zeros and their multiplicities are given, we can write the polynomial as the product of linear factors corresponding to each zero.

For this problem, the polynomial has zeros of -9 (multiplicity 1) and -1 (multiplicity 2), so the linear factors are:

(x + 9) and (x + 1)^2

To find the third factor, we use the fact that the degree of the polynomial is 3. We can multiply the linear factors together and then simplify:

(x + 9)(x + 1)^2 = (x^2 + 10x + 9)(x + 1)

= x^3 + 11x^2 + 19x + 9

Therefore, the polynomial with zeros of -9 (multiplicity 1), -1 (multiplicity 2), and degree 3 is:

f(x) = x^3 + 11x^2 + 19x + 9

The square root of 138 lies between 11 and 12, as 11²=121 and 12²=144.

Number is a mathematical object used to count, measure, and label. Numbers are used in almost every field of mathematics and science, including algebra, calculus, geometry, physics, and computer science. Numbers can also be used to represent data, such as population, income, temperature, or time. In addition, numbers are used to represent abstract concepts, such as love, truth, beauty, and justice.

This is because the square root of a number is the number that, when multiplied by itself, produces the original number. Therefore, to find the square root of 138, we need to identify two consecutive integers such that one of them squared is smaller than 138 and the other squared is larger than 138.

To do this, we can work our way up from the integer closer to 0, in this case 11. 11 squared is 121, which is smaller than 138, so we know that the square root of 138 must be between 11 and a larger integer. Then, if we square 12, we get 144, which is larger than 138. Therefore, we can definitively say that the square root of 138 lies between 11 and 12.

In other words, if a line is drawn parallel to one side of a triangle, and intersects the other two sides, then the ratio of the lengths of the line segments it creates on those sides is equal.

More formally, let ABC be a triangle, and let D be a point on the line segment BC that is between B and C. If the line through D parallel to AB intersects AC at point E, then BD/DC = AE/EC.

We can use the formula |a × b| = |a| |b| sin θ to solve for the magnitude of the cross product |a × b|, where θ is the angle between vectors a and b. In this case, we have |a × b| = 1 and θ = π/4, so we can write:

1 = |a| |b| sin(π/4)

Simplifying, we have:

|a| |b| = √2

Now, we need to find the dot product a · b. We know that:

a · b = |a| |b| cos θ

where θ is the angle between vectors a and b. Since we're given the angle between a and b, we can substitute θ = π/4 and use the value we found for |a| |b|:

a · b = (√2) cos(π/4) = (√2)/2

a) As per the given budget, the amount of interval that would be better for the city is 95% confidence interval.

b) The interval that be worse for the planners is depends on sample size

c) They achieve an interval estimate that would better serve their planning needs is depends on margin of error

d) The number of days worth of data should they collect to have confidence of estimating the true mean to 30 days

To obtain a better estimate, the city can create a confidence interval, which is a range of values that is likely to contain the true population mean with a certain degree of confidence.

However, there are also some disadvantages to using a confidence interval. The interval estimate may be wider than a point estimate, which means that the budget planners may have to allocate a larger budget to account for the uncertainty in the estimate.

To achieve a better interval estimate, the city could increase the sample size or reduce the variability of the data. Increasing the sample size reduces the margin of error and increases the precision of the estimate.

Finally, to determine how many days' worth of data the city should collect to estimate the true mean with a certain degree of confidence, the city would need to consider the desired level of precision, the variability of the data, and the desired level of confidence.

Typically, a larger sample size will provide a more accurate estimate, but this also depends on the variability of the data. In general, a sample size of at least 30 is recommended for a reasonably accurate estimate.
