Divide 71,290 with 2
71,290 / 2 = 35,645
Then, divide 35,645 with 12 ( because theres 12 months in 1 year )
35,645 / 12 = 2970.42
a) 2970.42 is your answer.

Answer:
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 38 minutes, standard deviation of 4.5 minutes.
Determine the interval that represents the middle 68% of her commute times.
Within 1 standard deviation of the mean. So
38 - 4.5 = 33.5 minutes
38 + 4.5 = 42.5 minutes.
The interval that represents the middle 68% of her commute times is between 33.5 and 42.5 minutes.
It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.
<h3>How to calculate the hourly delivery rate</h3>
Your information is incomplete. Therefore, an overview of the information will be given.
In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.
In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:
= $2000/240
= $8.33 per hour

Answer:
Step-by-step explanation:
Given: 
To solve this equation, we need to isolate 
on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add 
to both sides.
To isolate x, divide both sides by 7.
