Answer:

32 ft

Step-by-step explanation:

The perimeter is basically the area of the outside of a shape. To calculate this, you would add up all the sides together and get the answer.

8 + 8 + 8 + 8=32 or you can just do 8*4 which is also 32

So, the answer is 32

Answer:

A t-score of 2.0244 should be used to find the 99% 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 = 39 - 1 = 38

Now, we have to find a value of T, which is found looking at the t table, with 38 degrees of freedom(y-axis) and a confidence level of 0.99( $t_{99}$ ). So we have T = 2.0244.

A t-score of 2.0244 should be used to find the 99% confidence interval for the population mean
