Question

y=7.2x+58 If x represents the hours studying and y represents the tests score. What is the score after 1.5 hours?

Answer 1

The predicted test score after 1.5 hours of studying is 68.8.

To find the test score after 1.5 hours, we can substitute x = 1.5 into the equation y = 7.2x + 58

`y= 7.2(1.5) +58`

`y=68.8`

So, the predicted score after 1.5 hours of studying is 68.8.
