Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins. I pick Erik won and they asked,Use your previous answers to write an algebraic statement that represents all the ways your player will win. Be sure to define your variable

An algebraic statement that represents all the ways Eric will wins is , where
be the number that Eric thinks and
be the number that Nita thinks.
If the difference between their two numbers is less than, then Erik wins. If the difference between their two numbers is greater than
, then Nita wins.
Let be the number that Eric thinks and
be the number that Nita thinks.
For to Eric to win, the difference in the numbers should be less than.
That is, , for
or

volume=legnth times width times heigh ttimes width=3 times 5 times 6=90
volume=90
surface area=(2 times 3 times 5)+(2 times 3 times 6)+(2 times 5 times 6)=(2 times 15)+(2 times 18)+(2 times 30)=30+36+60=126

Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the residuals are all far from zero.
No, the equation is not a good fit because the sum of the residuals is a large number.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.
Answers
The equation that produced these predicted values is not a good fit given that the sum of the residuals is a large number.
What is the sum of the residuals in a regression equation?
The sum of the residuals in a regression is a value that is always supposed to be almost equal to zero in a regression analysis.
The residual tells us that the error term has been reduced to the minimum in the regression analysis.
