Step-by-step explanation:

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.

What 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,

Alita is 16 years oldJiro is 8 years oldErik is 12 years oldDawn is 36 years old

Start by writing -3x-5=16. You can add 5 to both sides since the inverse operation of negative is adding positive. You will then get 16+5=21. Then you will get -3x=21. Divide by -3 on both sides. -3x/-3. 21/-3=-7 x=-7. Now check your answer -3(-7)=21-5=16. Checks out. Hopefully this helps!
