Answer:
a) has the same probability of being selected
Step-by-step explanation:
A simple random sampling means that each possible sample of size n has the same probability of being selected.
Then your answer is:
a) has the same probability of being selected
= x·[2(x²- 4x + 4) + 3(x² + 6x + 9) - x² + 5x]
= x(2x² - 8x + 8 + 3x² + 18x + 27 - x² + 5x)
= x(4x² + 15x + 35)
This is similar to the other question you posted. Follow the same steps as before.
First find g(41).
g(41) = sqrt{x - 5}
g(41) = sqrt{41 - 5}
g(41) = sqrt{36}
g(41) = 6
We now find f(6).
f(6) = -7(6) + 1
f(6) = -42 + 1
f(6) = -41
Answer:
(fºg)(41) = -41
