A significance level of 0.10, we have enough evidence to conclude that the new copy machines have a significantly faster mean repair time compared to the older model.

To test if the new copy machines are faster to repair, we can set up the following null and alternative hypotheses:

Null Hypothesis (H₀): The mean repair time for the new copy machines is the same as the mean repair time for the older model.

Alternative Hypothesis (H₁): The mean repair time for the new copy machines is less than the mean repair time for the older model.

Let's perform a one-sample t-test to test these hypotheses. The test statistic is calculated as:

t = (sample mean - population mean) / (sample standard deviation / √(sample size))

Given:

Population mean (μ) = 93 minutes

Sample mean (\(\bar x\)) = 86.8 minutes

Sample standard deviation (s) = 14.6 minutes

Sample size (n) = 18

Significance level (α) = 0.10

Calculating the test statistic:

t = (86.8 - 93) / (14.6 / sqrt(18))

t = -6.2 / (14.6 / 4.24264)

t ≈ -2.677

The degrees of freedom for this test is n - 1 = 18 - 1 = 17.

Now, we need to determine the critical value for the t-distribution with 17 degrees of freedom and a one-tailed test at a significance level of 0.10. Consulting a t-table or using statistical software, the critical value is approximately -1.333.

Since the test statistic (t = -2.677) is less than the critical value (-1.333), we reject the null hypothesis.

The length of the segment SR for the given pentagons is 9 units.

A polygon having 5 sides and 5 angles is called a pentagon. The words "pentagon" (which implies five angles) are formed up of two other terms, namely Penta and Gonia. End to end, the sides of a pentagon come together to form a shape. Hence, there are 5 sides in a pentagon.

The pentagon is a polygon with five sides and five angles, just like other polygons including triangles, quadrilaterals, squares, and rectangles. There are several sorts of pentagon forms, including regular and irregular pentagons as well as convex and concave pentagons, depending on the sides, angles, and vertices.

We know that, for similar figures the length of the ratios of their corresponding segments are equal.

Thus,

NM/TS = ML/SR

4/7.2 = 5/x

Using cross multiplication we have:

4x = 5(7.2)

4x = 36

x = 9

Hence, the value of the segment SR for the given pentagons is 9 units.

11 years is the sum of Joey's two digits the next time his age is a multiple of Zoe's age.

Assume Chloe is c years old today, and Joey is c+1 years old today. Chloe and Zoe will be n+c and n+1 years old after n years.

Given,

(n + c) ÷ (n + 1) = 1 + ((c - 1) ÷ (n + 1))

For 9 non-negative integers, n is an integer. As a result, c - 1 has 9 positive divisors. c-1's prime factorization is either \(p^8\) or p²q². Because c - 1 < 100, the only possible solution is c - 1 = 2² × 3² = 36, from which c = 37. We may deduce that Joey is 38 years old today.

Assume Joey's age is a multiplier of Zoe's age after k years, resulting in Joey and Zoe being k + 38 and k + 1 years old, correspondingly.

Given,

(k + 38) ÷ (k + 1) = 1 + ((38 - 1) ÷ (k + 1))

For some positive integers, k is an integer. As 37 is divisible by k + 1, the only possible solution is k = 36. Infer that Joey will be k + 38 = 74 years old at that time, yielding the value 7 + 4 = 11.

Jazzlen's claim that over 50 of the 400 students have likely traveled outside the United States appears to be correct. The estimated number of students who have likely traveled is 56, which is greater than 50.

To determine whether Jazzlen's claim is correct, we need to analyze the information provided.

Jazzlen surveyed 50 students and found that 7 of them have traveled outside the United States. However, she is extrapolating this data to make a claim about the entire grade of 400 students.

If we assume that the 50 students she surveyed are representative of the entire grade, we can use this information to estimate the number of students in the grade who have likely traveled outside the United States.

Since 7 out of 50 students surveyed have traveled outside the United States, we can calculate the proportion or percentage of students who have traveled based on this sample. The proportion is calculated by dividing the number of students who have traveled (7) by the total number of students surveyed (50):

Proportion = 7/50 = 0.14

To estimate the number of students in the grade who have likely traveled, we can multiply the proportion by the total number of students in the grade:

Estimated number of students who have likely traveled = Proportion × Total number of students

= 0.14 × 400

= 56

According to this estimation, Jazzlen's claim that over 50 of the 400 students have likely traveled outside the United States appears to be correct. The estimated number of students who have likely traveled is 56, which is greater than 50.

However, it's important to note that this estimation is based on the assumption that the 50 students Jazzlen surveyed are representative of the entire grade. If the sample is not representative, the estimation may not be accurate. Additionally, this estimation does not provide certainty about the exact number of students who have traveled outside the United States; it only provides an estimate based on the sample data.

Mango = 0.5, Peach = 1.75

Step-by-step explanation:

Let x represent the price of mango

Let y represent the price of peach

Melanie: 8x + 6y = 14.50

Jaya: 4x + 7y = 14.25

Isolate for a variable in one of the equations (just pick a random one, you don't have to pick mine)

4x + 7y = 14.25 => x = (14.25 - 7y)/4 = 3.5625 - 7/4y

Plug into other equation

8x + 6y = 14.50

8(3.5625 - 7/4y) + 6y = 14.5

28.5 - 14y + 6y = 14.5

28.5 - 14.5 = 14y - 6y

14 = 8y

y = 1.75

4x + 7y = 14.25

4x + 7(1.75) = 14.25

4x + 12.25 = 14.25

The interval of convergence for the given power series is (2, 8).

To find the interval of convergence for the given power series. We have the power series:

∑(n=2 to ∞) ((x-5)ⁿ)/(3ⁿ)

To find the interval of convergence, we'll use the Ratio Test. For the Ratio Test, we need to compute the limit:

L = lim (n → ∞) |(a_(n+1)/a_n)|

For our series, a_n = ((x-5)ⁿ)/(3ⁿ). Therefore, a_(n+1) = ((x-5)(n+1))/(3(n+1)). Now, let's compute the ratio:

|(a_(n+1)/a_n)| = |(((x-5)(n+1))/(3(n+1))) / (((x-5)ⁿ)/(3ⁿ))|

Simplify the expression:

|(a_(n+1)/a_n)| = |(x-5)/3|

The series converges if L < 1. So we have:

|(x-5)/3| < 1

Now, we'll solve for x to find the interval of convergence:

-1 < (x-5)/3 < 1

Multiply each term by 3:

-3 < x-5 < 3

Add 5 to each term:

2 < x < 8

In solving a system of equations, we look for a point where the two lines intersect. The point of intersection will be a point that is a solution to both equations in the system. We can solve a system of equations by several methods, but one of the most common methods is using substitution or elimination.

To solve a system of equations using substitution, we have to solve one of the equations for one of the variables, and then substitute the result into the other equation. This process eliminates one variable and makes the system easier to solve. Therefore, the best choice that describes a possible first step in solving the system of equations is to solve for y in the second equation. Here is the step-by-step solution:2x - 7y = -14-2x + y = -10Solve for y in the second equation.-2x + y = -10y = 2x - 10Now substitute 2x - 10 for y in the first equation.2x - 7(2x - 10) = -14Simplify:2x - 14x + 70 = -14-12x + 70 = -14-12x = -14 - 70-12x = -84x = -84/-12x = 7Substitute x = 7 into either equation.

The answer to the multiple-choice question is 19%. The coefficient of multiple determination, also known as R-squared, measures the proportion of variation in the dependent variable that can be explained by the independent variables in a regression model.

In this case, if the R-squared is 0.81, it means that 81% of the variation in the dependent variable is explained by the independent variables.

To find out what percent of variation is not explained, we subtract the R-squared from 1 (or 100% in percentage terms). This is because the total variation in the dependent variable is either explained by the independent variables (R-squared) or unexplained (1 - R-squared).

So, the percent of variation that is not explained is:

1 - 0.81 = 0.19 or 19%
