Step-by-step explanation:
We are given,
The table representing the number of miles run in different weeks is,
Week Miles Run
1 5
2 8
4 13
6 15
8 19
10 20
Using the linear regression calculator, we see that,
<h3>The equation of the line best fit for the data is

(5/8) × 48 = (8/15) × n
Multiply by the inverse of the coefficient of n. That inverse is 15/8.
n = (15/8)×(5/8)×48 = (75/64)×48 = 225/4 = 56 1/4
5/8 of 48 is equal to 8/15 of 56 1/4
1. the total of an area under the curve must be equal to one. 2. Every point of the curve must have an vertical height that is 0 or greater.
