2) What is the solution of your equation?

3) fill in the blanks:

Alita is __ years old

Jiro is __ years old

Erik is __ years old

Dawn is __ years old


thanks!! :)

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

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

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.

Because the sample mean for students with a grade point average of 3.0–4.0 is
