Answer:

4x + 2

Step-by-step explanation:

-5 x 2 - 4x +8

- 10 - 4x + 8 - negative 5 times 2 = -10

-2 - 4x - negative 10 plus 8 = -2

4x - -2 - switch them around so you have 4x - -2

4x + 2 - two negatives make a positive

GenaCL600 [577]

Answer:

The alternative hypothesis is H_1: p > 0.6.

The critical value is Z_c = 1.645

Step-by-step explanation:

It is claimed that proportion in favor of proportion A is greater than 60%.

This means that at the null hypothesis, we test if the proportion is of at most 60%, that is:

H_0: p \leq 0.6

At the alternative hypothesis, we test if the proportion is more than 60%, that is:

H_1: p > 0.6

What is (are) the critical value?

The critical value is the value of Z with a p-value 1 subtracted by the standard significance level of 0.05, since we are testing if the mean is more than a value, so, looking at the z-table, Z_c = 1.645

You just looked at the graph of this system of equations. Why will the lines never intersect? y = –x + 5 y = –x – 3
IceJOKER [234]

Sample Response:

<em>The linear equations have the same slope, so the rate of change for each is the same. As long as the rate of change is the same, the lines will stay the same distance apart and not intersect.</em>
