If we find the factors of each and rewrite them like this:
16, 16 x 9, 16 x 9 x 9, etc.
We notice we are multiplying by a factor of 9 every time we increase the number of subscribers.

Answer:
0.9812
Step-by-step explanation:
Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds
For a sample of 9 people std error of sample would be
Thus we find that sample mean is N(175, 12)
The plane will lift safely if sample average <200 pounds
i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)
=
~0.981
