Leo is interested in the effects of sleep deprivation usage on number of calories consumed. he asks a group of 20 college students to spend the night in the sleep lab under one of the following conditions: no sleep, 2 hours of sleep, 4 hours of sleep, 6 hours of sleep, or 8 hours of sleep. leo measures how many calories are consumed by the students in the sleep lab, which is stocked with various food items. after collecting the data, leo performs an anova and finds that he can reject the null hypothesis. on the basis of this, what does leo know? a. he knows that there is a difference among the groups somewhere, but he does not know whare. b. he knows that a moderate amount of sleep is associated with incresed calorie consumption, but that fess aieep s anseclated with decreased calorie con c. he knows that sleeping any number of hours affects calorie consumption d. he knows that getting more sleep is associated with a greater consumption of calories.

2 & 7

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.
