4(x+5)+6=2(2x+3)
4x+20+6=4x+6
4x+26=4x+6
Get letters on left...so subtract 4x from right and do same to left
26=6 
no solution because 26 does not equal 6

suppose you create a graph of the cost function, c=20n + 500 of a new bookstore, and you also graph the revenue function, r=25n,
sdas [7]

Answer:

Loss section

Step-by-step explanation:

Given

c = 20n + 500 -- cost

r = 25n -- revenue

Required

Determine where n = 150 is

To do this, we substitute 150 for n in the given functions

c = 20n + 500

c = 20 * 150 + 500

c = 3500

r = 25n

r = 25 * 150

r = 3750

The above shows that the revenue is greater than cost for n = 150.

This implies that, n = 15o is the loss section.

Effectus [21]

Answer:

The value of the test statistic is of 0.22.

Step-by-step explanation:

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the expected mean, \sigma is the standard deviation(square root of the variance) and n is the size of the sample.

A lumber company is making boards that are 2920.0 millimeters tall.

This means that \mu = 2920.

A sample of 12 is made, and it is found that they have a mean of 2922.7 millimeters with a variance of 121.00.

This means that X = 2922.7, n = 12, \sigma = \sqrt{121} = 11. So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{2922.7 - 2922}{\frac{11}{\sqrt{12}}}

t = 0.22

The value of the test statistic is of 0.22.
