Answer:
100 - 4q²
Step-by-step explanation:
(10 - 2q)(10 + 2q)
each term in the second factor is multiplied by each term in the first factor.
10(10 + 2q) - 2q(10 + 2q) ← distribute parenthesis
= 100 + 20q - 20q - 4q² ← collect like terms
= 100 - 4q²

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
