Answer:
y = 5/6x -2
Step-by-step explanation:
Subtract 5x and divide by -6:
-6y = -5x +12 . . . .subtract 5x
y = 5/6x -2 . . . . . divide by -6
Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2So, 6=1+c/2 12=2+cc=$10
Carey earns $10 hourly<span>

Answer: 39
Step-by-step explanation:
Given
P(x)=7x+5
r(x)=x-1
r(p(x))=7x+5-1=7x+4
so, r(p(5))

Using the z-distribution, the p-value would be given as follows:
b) 0.0086.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis we test if the means are equal, hence:

At the alternative hypothesis, it is tested if they are different, hence:

<h3>What are the mean and the standard error for the distribution of differences?</h3>
For each sample, they are given as follows:
Hence, for the distribution of differences, they are given by:
.
<h3>What is the test statistic?</h3>
The test statistic is given by:

In which
is the value tested at the null hypothesis.
Hence:


z = -2.63.
Using a z-distribution calculator, for a two-tailed test, with z = -2.63, the p-value is of 0.0086.
Hence option B is correct.
