Ryan concludes that adults spend a mean of 8 hours working each day. malia thinks the mean is 9 hours. who is correct—ryan or malia? explain your answer in two or three sentences. make sure to use facts to support your answer.

You have to tell us all the numbers

Step-by-step explanation:

we cant find the mean without the numbers so if you write down the numbers i can solve the mean k

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
