the line of best is y = 0.20x + 5.43 and it will take 7.5 min to get to work in week 10.
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}[/tex]
[tex]\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have the data shown in the picture.
Let's suppose the line of best is:
y = mx + c
We can calculate the value of m and c using the formula.
m = 0.20
c = 5.43
The line of best will be:
y = 0.20x + 5.43
Plug x = 10 in the line of best fit:
y = 0.20(10) + 5.43
y = 7.43 ≈ 7.5 min
Thus, the line of best is y = 0.20x + 5.43 and it will take 7.5 min to get to work in week 10.
