The National Center for Education Statistics reports that the proportion of college freshmen who return to the same school for their sophomore year is 0.69. Suppose we select a random sample of 440 freshmen from across the nation. Question 1. What is the expected value of the sampling distribution model for the proportion of 440 freshmen that will return to the same school for their sophomore year

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

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 !
