Question

The table compares x, the number of minutes of television Sam watched each day, to y, the number of minutes she spent exercising. The function y = –0.78x + 95 models the data in the table.

A 2-column table with 5 rows. The first column is labeled minutes of television viewing, x with entries 45, 65, 120, 22, 80. The second column is labeled minutes of exercising, y with entries 60, 45, 5, 80, 25.

Which is the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day?
45 minutes
72 minutes
83 minutes
118 minutes

Answer 1

The answer is 72 minutes. Hope this helps!

Answer 2

The best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day is 72 minutes, the correct option is B.

What is the linear equation?

An equation is a mathematical statement with an equal sign (=) between the algebraic expression.

The function y = –0.78x + 95 models the data in the table.

The best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day is;

$\rm y = -0.78x + 95 \\\\y = -0.78(30)+95\\\\y=-23.4+95\\\\y=-71.6\\\\y=72$

Hence, the best prediction for the number of minutes of exercising Sam will do if she spends 30 minutes watching television that day is 72 minutes, the correct option is B.
