Answer:

a and b are positive

Step-by-step explanation:

We are given that

a-3>b-3

b>4

We have to find that a and b are positive or negative.

We have

b>4

It means b is positive and greater than 4.

a-3>b-3

Adding 3 on both sides

a-3+3>b-3+3

a>b>4

\implies a>4

Hence, a is positive and greater than 4.

Therefore, a and b are positive

If f(x) = -x2 + 4x - 9 and g(x) = x - 8, find g(f(-1))
Paha777 [63]

Answer:

-22

Step-by-step explanation:

f(x) = -x2 + 4x - 9

g(x) = x - 8,

g(f(-1))

First find f(-1)

f(-1) = - (-1)^2 + 4(-1) - 9 = -1 -4-9 = -14

The find g(-14)

g(-14) = -14-8 = -22

Private colleges and university rely on money contributed
Otrada [13]

Answer:

The point estimate for the mean endowment of all private colleges in the United States is 180.2125 million dollars.

Step-by-step explanation:

We are given endowments (in millions of dollars) of eight private colleges in the United States:

78.8, 50.3, 243.2,  489, 111.5, 163.7, 92.4, 212.8

We have to find the point estimate of the population mean endowment of all private colleges in the  United States.

The point estimate will be given by the sample mean.

\mu = \bar{x}

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{1441.7}{8} = 180.2125

Thus, the point estimate is 180.2125 million dollars.
