5 0

Answer:

The frame should be 36 + 2b + 16 + 2b

Step-by-step explanation:

To solve this question, let assign 36 in x 16 in as the dimension of the painting.

276 in^2 is the area of the framing material to be used.

Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

The essay lengths of 29 randomly sampled essays are used to estimate the mean of the population. What t-score should be used to
slavikrds [6]

Answer:

A t-score of 1.701 should be used to find the 95% confidence interval for the population mean

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 29 - 1 = 28

Now, we have to find a value of T, which is found looking at the t table, with 28 degrees of freedom(y-axis) and a confidence level of 0.95(t_{95}). So we have T = 1.701.

A t-score of 1.701 should be used to find the 95% confidence interval for the population mean

Inquashia took out a 2900 loan for a car the interest on the loan is a 8% compounded monthly how much in total will in Isha and
Shtirlitz [24]

Answer: the total amount after 6 years is 4690

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount of the loan at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount loaned.

From the information given,

P = 2900

r = 8% = 8/100 = 0.08

n = 12 because it was compounded 12 times in a year.

t = 6 years

Therefore,

A = 2900(1 + 0.08/12)^12 × 6

A = 2900(1 + 0.0067)^72

A = 2900(1.0067)^72

A = 4690
