A researcher studies the relationship between the number of hours of sleep per night and the performance on a
memory test. Study participants are randomly selected to
get no sleep or sleep in 1-hour increments, up to 8 hours
total (that is, the participant gets 1 hour, 2 hours, and so
on, up to 8 hours of sleep). The researcher determines
that the association between the two variables can be
modeled with the linear equation p = 9h + 15, where h is
number of hours of sleep and p is the percentage score
on the memory test. Use the slope in the equation to
describe the association between the hours of sleep and
the performance on the memory test.

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
