I attached a picture with the answer, hope this helps :)
Mean the the total of all values, divided by the number of values
Answer: The answer is x = 20 feet
Step-by-step explanation: I am right because there is 4 feet below the ground and 16 feet above the ground so if you add 4 + 16 = 20 which is the total feet of the pole.
Answer:
D. 914 feet
Step-by-step explanation:
We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;
We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

Given d is 25.2, h becomes;

To the nearest whole number, h becomes 914
