Answer:

The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.

Step-by-step explanation:

When we have a sample, the mean of the sample is used as the point estimate for the mean of the entire population.

What value will be used as the point estimate for the mean endowment of all private colleges in the United States?

We have to find the mean of the 8 colleges. So

$M = \frac{60.2 + 47.0 + 235.1 + 490.0 + 122.6 + 177.5 + 95.4 + 220.0}{8} = 180.975$

The value will be used as the point estimate for the mean endowment of all private colleges in the United States is of 180.975 millions of dollars.

The quadratic polynomial x^2 +mx+n has roots twice those of x^2 +px+m, and none of m,n, and p is zero. What is the value of n/p?

olga_2 [115]

Answer:

n/p = 8.

Step-by-step explanation:

If the roots of the first equation are A and B we have

A + B = -m and AB = n.

This has roots twice the roots of the second equation so we have:

0.5(A + B) = -p and 0.25AB = m.

So A + B = -2p and AB = 4m

Equating values of A +B and AB:

-m = -2p and n = 4m

m = 2p and m = n/4

2p = n/4

n = 8p

n/p = 8.
