A regression was run to determine if there is a relationship between hours of study per week (x) and the test scores (y). The results of the regression were: y=ax+b a=6.332 b=21.34 r?=0.5184 r=0.72 Use this to predict the final exam score of a student who studies 7 hours per week, and please round your answer to a whole number.

For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495).
