Step-by-step explanation:

First of all, we need to figure out which "category" each observation belongs to. Then we need to count the number of observations in each category and enter that count in the table.

I have numbered the categories 1-4 from top to bottom so that you can see how I have assigned observations to categories. The numbers on the right in the table are the ones the problem is asking for. (6, 2, 3, 3)

Solve the linear system using substitution

levacccp [35]

Hello there!

3x - y = 3
-x + y = 3

We need to solve 3x - y = 3 for y

Let start by adding -3x to both sides

3x - y = 3

3x - 3x - y = 3 - 3x

-y = 3 - 3x
We cannot leave the variable with a negative sign. We must multiply both sides by -1

-y * -1= (3 - 3x)-1

y = 3x - 3

Substitute 3x -3 for y in -x+y=3

-x + y = 3

-x + 3x - 3 = 3

2x - 3 = 3

2x = 3 + 3

2x = 6

x = 6/2

x = 3

Now substitute 3 for x in y=3x -3

y = 3x - 3

y = 3(3) - 3

y= 9 - 3

y= 6

Thus,

The answer is x=3 and y=6

It is always my pleasure to help students like you :)
