Answer:
7x + 32 and 123
Step-by-step explanation:
One way to divide is to use the divisor as a factor in the numerator
Consider the numerator
7x(x - 4) + 28x + 4x - 5
= 7x(x - 4) + 32(x - 4) + 128 - 5
= 7x(x - 4) + 32(x - 4) + 123
quotient = 7x + 32 and remainder = 123
= x + 32 + 
Based on the results of the study, the conclusion which is valid is There is correlation between the increase in the rate of televised political attack ads since the previous congressional election and the rate of voter dissatisfaction in the observed districts.
<h3>What doe
s the study conclude?</h3>

The fact that both the rate of voter dissatisfaction and televised political attack ads moved together means that they correlate with each other.
It is important to note however, that correlation does not equate causation so there might be no link between the two rates.

A suitable probability app shows the 1st percentile to be at about 11040 pages.
_____
The app shown has an error in the first decimal digit. The number is closer to 11040.82301. We expect the manufacturer would round to the nearest 10 or 50 or 100 in advertising.
Considering the desired result of the hypothesis test, we the closest mean time to 1.5 hours, hence the correct option is:
C. 1.6 hrs
<h3>What should be the mean?</h3>
The closer the mean is to the sample mean, the less likely we are to reject the null hypothesis.
In this problem, the sample mean is of 1.5 hours, hence, the closest value, considering the absolute value of the difference, is of 1.6 hours, hence option C is correct.
