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.

Here n=3

The given statement is related to eigenvalues of a matrix.

Let A be an n x n matrix with eigenvalues λ1, λ2,...,λn then the algebraic multiplicity of λi is the number of times that λi appears as a root of the characteristic equation of A and denoted by mi.

The sum of the algebraic multiplicities of all eigenvalues of a matrix is equal to the order of that matrix.

For example, if a matrix is of order 3 then the sum of all algebraic multiplicities of its eigenvalues is 3.

Now, for the given question, the statement is: An n x n matrix M has exactly three eigenvalues of algebraic multiplicities m1, m2, and m3, respectively. Then n ____ m1 + m2 + m3.

As the matrix M has exactly three eigenvalues, we can say that n = 3.

Therefore, n = 3 and m1 + m2 + m3 = n.Hence, n = 3 and m1 + m2 + m3 = n.

Option d, none of the above statements are incorrect. Confidence intervals are always close to the true population values. However, it varies from sample to sample, and the key to constructing confidence intervals is to understand what kinds of similarities can be found in different samples of the same population.

A confidence interval for a mean provides us with a range of feasible population mean values. If a confidence interval excludes a certain number, it is unlikely that the specific value represents the genuine population mean.

The sample mean will differ from sample to sample, but when the technique estimate margin of error is applied to generate an interval based on each sample, C% of these intervals accurately represent the unknown population mean.

Step-by-step explanation:

The total amount accrued of Eva principal plus interest, with compound interest on a principal of $500.00 at a rate of 4% per year compounded 365 times per year over 15 years is $911.03.

The total amount accrued of Amira principal plus interest, with compound interest on a principal of $500.00 at a rate of 4% per year compounded 12 times per year over 15 years is $910.15.

Compounded interest adds interest not only to your principle amount, but your accumulated interest over time.

To calculate compound interest we use the formula below where A = total balance after t years, P = principal amount (amount borrowed or invested), r = interest rate (decimal form), and t = time in years.  

Eva invested $500 in an account paying an interest rate of 4 5/8% compounded daily.

A = $911.03

A = P + I where

P (principal) = $500.00

I (interest) = $411.03

First, convert R as a percent to r as a decimal

r = R/100

r = 4/100

r = 0.04 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 500.00(1 + 0.04/365)(365)(15)

A = 500.00(1 + 0.00010958904109589)(5475)

A = $911.03

Hence, The total amount accrued of Eva principal plus interest, with compound interest on a principal of $500.00 at a rate of 4% per year compounded 365 times per year over 15 years is $911.03.

Amira invested $500 in an account paying an interest rate of 4 3/4% compounded monthly.

Given Principal (P) = $500

Interest rate (r) = 6%

Time (t) = 15 years

By taking compound interest formula:

\(A = P(1+\frac{r}{n} )^{\frac{n}{t} }\)

First, convert R as a percent to r as a decimal

r = R/100

r = 4/100

r = 0.04 rate per year,

Then solve the equation for A

\(A = P(1+\frac{r}{n})^{\frac{n}{t} }\)

A = 500.00(1 + 0.04/12)(12)(15)

A = 500.00(1 + 0.0033333333333333)(180)

A = $910.15

Hence the answer is, The total amount accrued, principal plus interest, with compound interest on a principal of $500.00 at a rate of 4% per year compounded 12 times per year over 15 years is $910.15.

The easiest way to find the surface area of a given shape is to use the formula for the area of the surface.

This formula, A = 2πr2 + 2πrh, is used to calculate the surface area of a shape with a circular base and a height, such as a cylinder. The formula requires two measurements, the radius (r) and the height (h). Once these two measurements are known, it is a simple matter to plug them into the formula and calculate the surface area. For example, if a cylinder has a radius of 3 cm and a height of 4 cm, then the surface area is calculated by plugging those values into the formula: A = 2π(3 cm)2 + 2π(3 cm)(4 cm) = 94.2 cm2. Thus, the surface area of this cylinder is 94.2 cm2.

The scale factor of 10cm to 5m is 50.

The scale factor is a measure for similar figures, who look the same but have different scales or measures.

For example ,if a length of 5cm is doubled and it gives a length 10cm, the scale factor is 10/5 = 2. This means that we can express scale factor with a formula;

scale factor = new dimension / old dimension

Here, the old dimension is 10cm and the new dimension is 5m. We need to convert the 5m into cm

therefore 5m = 5× 100 = 500cm

therefore scale factor = 500/10 = 50

Exact volume = 30,000 + 5,000pi cubic mm

Approximate volume = 45,700 cubic mm

========================================================

Explanation:

Break the figure into two pieces.

The top part is a half-cylinder with radius r = 20/2 = 10 mm and height h = 100 mm.

The volume of this half-cylinder is

V = 0.5*(full cylinder volume)

V = 0.5*pi*r^2*h

V = 0.5*pi*10^2*100

V = 5000pi

This is exact in terms of pi.

The lower part is a 20 mm by 100 mm by 15 mm rectangular block. It has volume of length*width*height = 20*100*15 = 30,000 cubic mm.

---------

We'll add the two volumes found earlier to get the overall volume.

The total exact volume is 30,000+5,000pi cubic mm.

To get an approximation, you can use something like pi = 3.14

30000+5000pi = 30000+5000*3.14 = 45,700 cubic mm is the approximate volume when using pi = 3.14
