Answer and Step-by-step explanation:

Hello!

To calculate variance, we start by calculating the mean, or average of your question. Then, we subtract the mean from each data point, and square the differences. Next, we add up all the squared differences. Now, the last step is to divide The sum by n minus 1, where n equals the total number of data points from your question!

Hope this helps you!

Hugs,

Josh

8x+3&gt;_x+10 how do i solve dis<br> HELP
VashaNatasha [74]

Answer:

x > 1

Step-by-step explanation:

Subtract 3 from both sides

8x + 3 - 3 > x + 10 - 3

Simplify

8x > x + 7

Subtract x from both sides

8x - x > x + 7 - x

Simplify

7x - 7

Divide both sides by 7

7x/7 > 7/7

Simplify

x > 1
