For the bottom graph slope = 2 and when x = -1 f(x) = -3 so equation is
f(x )= 2x - 1.
{ 2x - 1 ( x <= -1)
f(x) = {
{ x ( x >= 1)
2:5
4:10
66:165
Is that correct?
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
