Answer:

Step-by-step explanation:

We can use the formula distance = rate x time to solve the problem.

The rate is 15 miles per hour and the time is 3 1/3 hours.

To work with the time, we need to convert it to an improper fraction:

3 1/3 = (3 x 3 + 1)/3 = 10/3

Now we can plug in the values:

distance = 15 x 10/3

distance = 50 miles (rounded to the nearest mile)

Step-by-step explanation:

If a basketball player has a free-throw shooting percentage of 43%, it means that she makes 43% of her free throws on average. Therefore, the probability that she will miss her next free throw is equal to the complement of her shooting percentage, which is 1 minus 0.43. This simplifies to 0.57 or 57%. So, the probability that she will miss her next free throw is 57%.

the x-value that makes the two equations equal is x = -1. and x=0.

An equation consists of two parts: the left-hand side (LHS) and the right-hand side (RHS), connected by an equals sign (=). The LHS and RHS may contain one or more variables, which are values that can change or vary.

The first equation, y = -3/2, is a horizontal line with a y-intercept of -3/2. This means that no matter what x-value we plug in, the corresponding y-value will always be -3/2.

The second equation, y = (1/2) x - 1, is the equation of a line with slope 1/2 and y-intercept -1. To find the x-value(s) where this equation equals -3/2, we can set the two equations equal to each other:

-3/2 = (1/2) x - 1

Adding 1 to both sides, we get:

-1/2 = (1/2) x

Multiplying both sides by 2, we get:

-1 = x

At x=0, two equation satisfy the condition.

Therefore, the x-value that makes the two equations equal is x = -1 and 0.

Answer:

D

Step-by-step explanation:

First, let's calculate the initial monthly payment without purchasing any points.

The amount of the mortgage after the 20% down payment is:

$125,000 x 0.8 = $100,000

To calculate the monthly payment, we can use the formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1]

Where:

M = Monthly payment

P = Principal (loan amount)

i = Interest rate (per month) = 4.75% / 12 = 0.0039583

n = Number of payments = 30 years x 12 months per year = 360

So, plugging in the values:

M = $100,000 [ 0.0039583(1 + 0.0039583)^360 ] / [ (1 + 0.0039583)^360 – 1]

M = $522.12 (rounded to the nearest cent)

Now, let's calculate the new monthly payment if Ashlee purchases 2 points. Each point costs 1% of the loan amount, so for a $100,000 loan, each point is $1,000.

By purchasing 2 points, Ashlee would pay an additional $2,000 upfront (2 x $1,000). This will lower the interest rate on the loan by 0.5%, from 4.75% to 4.25%.

Using the same formula as before, but with the new interest rate of 4.25% / 12 = 0.0035417, we get:

M = $100,000 [ 0.0035417(1 + 0.0035417)^360 ] / [ (1 + 0.0035417)^360 – 1]

M = $505.16 (rounded to the nearest cent)

The difference in monthly payments is:

$522.12 - $505.16 = $16.96

Rounding to the nearest cent, the answer is option D, $14.96.

Part A: The probability of rolling a 5 is 1/6 or approximately 0.167. Part B: the probability of rolling an even number is 3/6 or 1/2 or 0.5.

Probability is a branch of mathematics concerned with measuring the likelihood or chance of an event occurring. It is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. Probability is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event will definitely occur. For example, if the probability of an event is 0.5, it means that the event has an equal chance of occurring or not occurring. Probability is used in various fields, such as science, engineering, finance, and statistics, to make predictions and make decisions based on uncertain events.

Part A:

The number cube has six faces, and each face has an equal chance of landing face-up. Therefore, the probability of rolling a 5 is 1/6 or approximately 0.167.

Part B:

The even numbers on a number cube are 2, 4, and 6. There are three even numbers out of a total of six possible outcomes. Therefore, the probability of rolling an even number is 3/6 or 1/2 or 0.5.

Answer: 90 feet

Step-by-step explanation:

Since the baseball diamond is shaped like a square, all sides are equal in length.

Let's denote the length of each side by x.

The perimeter of a square is the sum of the lengths of all four sides, so we can write:

4x = 360

Dividing both sides by 4, we get:

x = 90

Therefore, each side of the baseball diamond is 90 feet long.

Using compounding we know that the additional amount Jason has more than Kayden is $249.48.

Calculating interest on the principal borrowed as well as any prior interest.

In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one.

So, the amount of Jason after 8 years:

Amount: $5500

Interest: 1.875%

Compounded: Quarterly

Using a compounding calculator:

Amount after 8 years: $6,387.85

The amount of Kayden:

Amount: $5500

Interest: 1.375%

Compounded: Quarterly

Using a compounding calculator:

Amount after 8 years: $6,138.37

The additional amount Jason got: 6,387.85 - 6,138.37 = $249.48

Therefore, using compounding we know that the additional amount Jason has more than Kayden is $249.48.

3x-6=180

3x=186

x=62degrees

Solve for y

7y+47=180

7y=180-47

7y=133

y=19degrees

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.

Step-by-step explanation:

The find the value of x on the given diagram, we must first find the included angle between the two line segments labelled 94 mi and 119 mi in the triangle. To do this, we can use the Law of Cosines.

[tex]\boxed{\begin{minipage}{6 cm}\underline{Law of Cosines} \\\\$c^2=a^2+b^2-2ab \cos C$\\\\where:\\ \phantom{ww}$\bullet$ $a, b$ and $c$ are the sides.\\ \phantom{ww}$\bullet$ $C$ is the angle opposite side $c$. \\\end{minipage}}[/tex]

The values to substitute into the formula are:

Solving for the angle C:

[tex]\begin{aligned}173^2&=119^2+94^2-2(119)(94)\cos C\\\\29929&=14161+8836-22372\cos C\\\\29929&=22997-22372\cos C\\\\6932&=-22372\cos C\\\\-\dfrac{6932}{22372}&=\cos C\\\\C&=\cos^{-1}\left(-\dfrac{6932}{22372}\right)\\\\C&=108.0502874...^{\circ}\end{aligned}[/tex]

As angles on a straight line sum to 180°, the value of x can be calculated by subtracting the found value of C from 180°:

[tex]x=180^{\circ}-108.0502874...^{\circ}[/tex]

Answer: B. Symmetric.

Explanation:

In a symmetric distribution, the data is evenly distributed around the mean or median, creating a mirror image on both sides of the center. In this histogram, the median and mean are very close together at 55 and the bars on both sides of the center are roughly equal in height, indicating a fairly even distribution. Therefore, the histogram is symmetric.

This illustrates the rule of large numbers, according to which the sample mean approaches the population mean as the sample size rises.

The likelihood or chance of an occurrence occurring is measured by probability. It is expressed as a number between 0 and 1, with 0 denoting impossibility and 1 denoting certainty of the occurrence. Additionally, probabilities can be stated as percentages, with 0% denoting an improbable event and 100% denoting a specific event. By dividing the number of favourable outcomes by the total number of potential outcomes, the probability of an occurrence is determined.

Step-by-step explanation:

20/8=2r4

2r4= 2 4/8

2 4/8 = 2 1/2

Answer:

2 1/2

Step-by-step explanation:

Step 1:

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

20/8= 2.5 = 2

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (2) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:

20 - (8 x 2) = 4

Step 3: Our mixed fraction

We've now simplified 20/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

2 4/8

Step four: Convert it by simplifying

2 4/8 = 2 1/2

The distribution of Z=X+Y is gamma(1,10), which has a probability density function f(z) = 10 × e^(-10z), 0 ≤ z.

The moment generating function (mgf) of Z=X+Y can be found by taking the product of the mgfs of X and Y

Mz(t) = Mx(t) × My(t) = (e^(-4+4t))×(e^(-6+6t)) = e^(-10+10t)

We recognize that Mz(t) is the mgf of the gamma distribution with shape parameter k=1 and rate parameter λ=10. Therefore, Z=X+Y follows a gamma distribution with shape parameter k=1 and rate parameter λ=10.

In summary, the distribution of Z is gamma(1,10), which has a probability density function f(z) = λ^k × z^(k-1) × e^(-λz) / Γ(k) where k=1 and λ=10. Therefore, the probability density function of Z is f(z) = 10 × e^(-10z), 0 ≤ z.

Answer:54 inches

Step-by-step explanation:

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.

There is no second place winner. all three competitors picked the same amount of strawberries, so there is a tie for first place.

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

The problem states that each of the three competitors picked 1 pound of strawberries. Since all of them picked the same amount, there is no way to determine who came in second. All three competitors can be considered tied for first place. If the problem had given different weights of strawberries picked by each competitor, then we could have compared the weights and determined who picked the second greatest amount of strawberries. But since all three competitors picked the same amount, there is no way to determine a second place winner.
