Below are the data collected from two random samples of 500 american adults on the number of hours they work per day rounded to the nearest hour ryan concludes that adults spend a mean of eight hours working each day malia thinks the mean is nine hours who is correct ryan or melia explain your answer in two or three sentences make sure to use facts to support your answer

The mean is 8 hours. So, Ryan is correct.

To find the mean, we will multiply the number of people who gave each response by the number of hours.  We will add these values and divide by the number of people surveyed.

In the first sample, we have

60(6) + 7(90) + 8(145) + 9(150) + 10(55) = 4050

In the second sample, we have

70(6) + 7(80) + 8(140) + 9(145) + 10(65) = 4055

Adding these we get,

We have a total of 1000 people, so we will divide this by 1000:

Or rounding it off we get the mean as 8.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
