)let x1, x2, . . x80 be a random sample of size 80 taken from the population with p. d.f. f(x) = 3x 2 , 0 < x < 1. find the mean and variance of the population and then use the central limit theorem to approximate p(58 ≤ x 80 i=1 xi ≤ 64). show your work.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

yes because they have the same amount of green and blur marbles.
