Finding the regression equation, her average speed on the 9th day should be expected to be of 6.92 minutes per mile.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
Researching the problem on the internet, the values of x and y are given as follows:
- Values of x: 1, 2, 3, 4, 5, 6.
- Values of y: 8.2, 8.1, 7.5, 7.8, 7.4, 7.5.
Hence, using a calculator, the equation for the average minutes per mile after t days is given by:
V(t) = -0.15143t + 8.28
Hence, for the 9th day, t = 9, hence the estimate is:
V(9) = -0.15143(9) + 8.28 = 6.92 minutes per mile.

The inverse would be y=-1/2x+3 because the inverse is the negative of the function. to make the function negative make the slope negative and keep the y-intercept.
I hope I've helped!
8/8 hours because he can play for a longer amount of time
Answer: step by step down there =)
Step-by-step explanation: First times 2 by 3 then times 2 by 2 ok now you should have 6b and 4b now you subtract 6b and 2 and then add 4b and 12 after you add them you should have 4b and 16b so you answer would be 4b = 16b
