of the passengers on a 757 airliner, 40% are female. a random sample of 25 passengers is selected. what is the expected number of female passengers in the sample?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
