Based upon data from his AP United States History class, Mr. Unsworth determined that the relationship between a student's hours watching TV per week (x) and that student's score on the AP (y) exam were
negatively correlated. He determined that the equation of the best fit line is y = -0.212 + 5.22. Based upon
these results, predict a student's AP score (to the nearest whole number) if he watches 12 hours of TV a week.

Step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
