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!!!

They both have the same rate of change
Answer:
110
Step-by-step explanation:
Using pythagorean theorm
c^2 = a^2 + b^22
610^2 = 600^2 + b^2
372100 = 360000 + b^2
b^2 = 12100
b = 110
