Garret studies number of hours sleep per night among students who have a grade point average of 3.0–4.0 versus students who have a grade point average of 2.0–3.0.
His theory is that students who get more sleep will have a higher grade point average than students who get less sleep because they are more rested and, therefore, better able to concentrate.
In his samples, the mean number of hours of sleep students with a grade point average of 3.0–4.0 received each night was 6.8. The mean number of hours of sleep students with a grade point average of 2.0–3.0 received each night was 6.4.
Assuming there are no outliers or skew, do the results support Garret's theory?
Select from the drop-down menus to correctly complete the statements.
Since the samples were large and randomly chosen, we can use the samples to understand the populations.

Answer:
dudee 4 months ago you asked this question I feel bad.
Step-by-step explanation:
1) The Equation to represent the situation is
x+ x/3 + x/3-4 + 2( x/3 - 4)= 72
2) Alita is 16 years old
Jiro is 8 years oldErik is 12 years oldDawn is 36 years oldWhat is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the age of Dawn be x.
then age of Erik = x/3
Now, Jiro is 4 years younger then Erik.
Jiro's age = x/3 - 4
and, Alita is 2 times as old as Jiro.
So, Alita's age be = 2( x/3 - 4)
As, The sum of all their ages is 72.
x+ x/3 + x/3-4 + 2( x/3 - 4)= 72
x+ x/3 + x/3-4 + 2x/3 - 8 = 72
7x/3 - 12 = 72
7x/3 = 84
x = 36
Thus,

If it takes 5 1/4 minutes to make one cut through a log, how long will it take to cut a 5 ft log into 5 equal pieces?
Answers
Answer:
131.25
Step-by-step explanation:
5.25*(5*5)
Answer:
How many cuts are needed to cut the log into 5 equal pieces.
Hopefully you figure out that it takes 4 cuts.
Now if it takes 20 minutes in total then each cut would take how long.
Divide the total time by number of cuts.
So each cut takes 5 minutes.
Now figure out how many cuts are needed to get ten equal pieces and multiply by 5 minutes
