Answer:

13.27 cm

Step-by-step explanation:

I am using (xy) to mean the length of the side xy

7^2 + (xy)^2 = 15^2

49 + (xy)^2 = 225

(xy)^2 = 225-49

(xy)^2 = 176

Side (xy) = sqrt(176) = 13.2664991614 = 13.27 cm

The perimeter of the rectangle is 62 square units.

The perimeter of a rectangle can be calculated using the formula:

P = 2(L + W)

Where:

L is the length of the rectangle

W is the width of the rectangle

We have:

L = 20 units

W = 11 units

Substituting into the formula:

P = 2(20 + 11)

P = 2(31)

P = 62 square units

Based on the information provided, the total length of the worms would be 6 1/2 inches.

The graph presented shows the length of the worms Abe measured, based on the graph we know that the shortest worm was 2.125 inches, while the longest worm was 2.875 inches. Using this information, let's now add the three shortest worms together:

2.125  inches + 2.125  inches + 2.25 inches = 6.5 inches in total, which can be expressed ad 6 1/2.

Based on this, the total length of the three shortest worms would be 6 1/2.

If 38 items are chosen at random, the probability that their mean length is greater than 13.7 inches is 0.399.

What is probability?

Probability is simply the possibility that something will happen. When one doesn't know how something will turn out, one can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

A Z-score is a metric that quantifies how closely a value relates to the mean of the set of values. Standard deviations from the mean are used to measure Z-score.

Given that mean of 13.6 inches, and standard deviation of 2.2 inches.

mean, m=13.6

standard deviation, s=2.2

mx=m=13.7

Sample size,n=38

sx=s/√n=2.2/√38=0.356

P(x<13.6)=P(x-m/s < 13.7-13.6/0.356)

P(Z< -0.2809)

Using the normal distribution, it is found that there is a 0.7549 = 75.49% probability that a randomly generated value of X is greater than a  randomly generated value of Y.

In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem:

The the distribution of X - Y, we have that:

\(\mu = \mu_X - \mu_Y = 30 - 25 = 5\)

\(\sigma = \sqrt{\sigma_X^2 + \sigma_Y^2} = \sqrt{6^2 + 4^2} = 7.2111\)

The probability that a randomly generated value of X is greater than a  randomly generated value of Y is P(X - Y) > 0, which is 1 subtracted by the p-value of Z when X = 0, hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{0 - 5}{7.2111}\)

\(Z = -0.69\)

\(Z = -0.69\) has a p-value of 0.2451.

1 - 0.2451 = 0.7549.

0.7549 = 75.49% probability that a randomly generated value of X is greater than a  randomly generated value of Y.

Answer:

C. y=36(1.2)t

Step-by-step explanation:

The number of members in the Club in t years after 2001 is given by an equation in the following format:

\(y = y(0)(1+r)^{t}\)

In which y(0) is the number of members in 2001 and r is the growth rate, as a decimal.

The number of members in the Triathlon Club was 36 in 2001 and has increased by 20% each year.

This means that \(y(0) = 36, r = 0.2\)

So

\(y = y(0)(1+r)^{t}\)

\(y = 36(1+0.2)^{t}\)

\(y = 36(1.2)^{t}\)

The correct answer is C.

By evaluating g(x) in x = 8, we will get the value:

g(8) = -43

Here we have the following function:

g(x)= x⁶ - 64x⁴ + x² - 7x - 51

And we want to evaluate this function, where evaluating a function just means that we need to replace the variable by the indicated number.

Here we want to find g(8), this just means that we need to replace all the "x" in the equation by the number 8, we will get:

g(8) = 8⁶ - 64*8⁴ + 8² - 7*8 - 51

Now we only need to solve the right side, we will get:

g(8) = 8⁶ - 64*8⁴ + 8² - 7*8 - 51

g(8) = -43

That is the value of the function g(x) evaluated in x = 8.

In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:

Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.

Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.

These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).

Therefore, in order for zyx ~ wvu to be correct, the congruence of corresponding angles and the proportionality of corresponding sides must hold true.

From the question, we were told that the students earned $708 and they want to make $3710. we are to calculate the percentage they need to achieve the goal.

A percentage is calculated by the product of the ratio of part to the whole and 100 percentage.

So, using the percentage calculation formula:

Percentage = Part x 100%

Whole

So,

Let cost earned by selling candy be S = $708

Let cost required for a club trip be T = $3710

We can then find the percent of earned $708 from total $3710 as follows:

P = S/T x 100%

P = 708 x 100%

3710

P = 354 x 100%

1855

P = 0.19083 x 100%

P = 19.083%

Therefore, P = 19.1%

Hence, 19.1% of their goal has been reached.

The probability of a negative return if the returns are normally distributed, we can use the mean and standard deviation of the returns and If the distribution is symmetrical but otherwise unknown, it may be more difficult to estimate the probability of a negative return without more information about the shape of the distribution.

To determine how confident we can be that the mean of the given data sample is greater than 40, we would need to perform a statistical test such as a t-test or a z-test to compare the sample mean to the value of 40.

We would need to know the sample size, standard deviation, and any other relevant information about the data to calculate the appropriate test statistic and determine the p-value, which would tell us the probability of observing a sample mean as extreme as the one we obtained if the true population mean was actually 40.

To determine how confident we should be that the portfolio manager will continue to produce positive returns, we would need to analyze the distribution of returns and determine whether it is skewed or symmetrical and whether it follows a normal distribution or a different distribution. If the distribution is skewed or non-normal, it may be more difficult to estimate the probability of positive returns. However, if the distribution is symmetrical and follows a normal distribution, we can use the mean and standard deviation of the returns to calculate the probability of a positive return using the normal distribution.

If the returns of the investment strategy are normally distributed, we can use the mean and standard deviation of the returns to calculate the probability of a negative return using the normal distribution.
