Answer:
2623.6144m²
Step-by-step explanation:
Total Surface Area of a Square Pyramid
a * (a + √(a² + 4h²))
where,
a = area of base
h = height
Using the formula above
a * (a + √(a² + 4h²))
data given :
a = 36
h = 4
a * (a + √(a² + 4h²))
T.S.A. = a * (a + √(a² + 4h²))
Inputting values
T.S.A. = 36 * (36 + √(36² + 4 * 4²))
T.S.A. = 36 * (36 + √(36² + 4 * 16))
T.S.A. = 36 * (36 + √(36² + 64))
T.S.A. = 36 * (36 + √(1296 + 64))
T.S.A. = 36 * (36 + √(1360))
T.S.A. = 36 * (36 + 36.87817782917154)
T.S.A. = 36 * (72.87817782917154)
T.S.A. = 36 * 72.8782
T.S.A. = 2623.614401850175
Therefore Total Surface Area (T.S.A.) is 2623.6144m²
Answer:
The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.
Step-by-step explanation:
When we have a sample, the mean of the sample is used as the point estimate for the mean of the entire population.
What value will be used as the point estimate for the mean endowment of all private colleges in the United States?
We have to find the mean of the 8 colleges. So

The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.
Yes he is correct because a horizontal line goes straight across
