Answer:
Dan is correct
Step-by-step explanation:
First, I calculated the amount of hours that the graph shows in total, coming up with a total of 3,085 hours. I do this by multiplying the number of adults surveyed by the number of hours they spent. So for the first column, (80+70)*1, second column, (90+80)*2, third column, (135+130)*3, fourth column, (140+135)*4, and fifth column, (65+75)*5 if you get what I mean. Then I add up all values. Knowing that there were two sets of 500 American adults interviewed already, I came to the conclusion that 1,000 total adults were surveyed. Finally, I divided the total number of hours(3,085) by the total number of adults interviewed (1,000) to get a mean of 3.085 hours, rounding it to 3 hours and proving that Dan is correct.

The measure of the angle TRS is 34 degrees
<h3>Line and angles</h3>
The point where two lines meet is known as an angle
Given the following parameters
<QRS = 88 degrees
<QRT = 54 degrees
Using the expression
<QRS = <QRT + <TRS
Substitute the given parameters
88 = 54 + <TRS
<TRS = 88 - 54
<TRS = 34 degrees
Hence the measure of the angle TRS is 34 degrees
