Question

In a recent 10-year period, the change in the number of visitors in the U.S. National parks was about -11,150,000. What was the mean yearly change in the number of visitors?

Answer 1

Answer:

Mean = -1,115,000 per year.

Step-by-step explanation:

Mean = (Σx)/N

The mean is the sum of variables divided by the number of variables

Σx = sum of variable = change in number of visitors over a 10 year period = -11150000

N = number of variables = 10

Mean = (-11150000)/10

Mean = -1,115,000 per year.

Hope this Helps!!!
