Answer:
The mean is 8.
Step-by-step explanation:
The mean is the sum of a set of numbers divided by the number of numbers in a set. In this case, you add up all the numbers to get 56, and divide by 7 to get 8.
Using the Pythagorean Theorem we can solve.
20^2 - 12^2 = X^2
400 - 144 = X^2
256 = X^2
X = √256
X = 16 feet.
The answer is D.
