Answer 1

The line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025

What is the line of best fit?

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.

We have data shown in the table:

To find the line of best fit, we will calculate its slope and y-intercept.

We know the slope is given by:

$\rm m = \dfrac{n\sum xy-\sum x \sum y}{n \sum x^2 - (\sum x)^2}$   where n = 5

After calculating, we get,

$\rm n\sum xy-\sum x \sum y = 105000$  and

$\rm n \sum x^2 - (\sum x)^2 = 50$

m = 105000/50 = 2100

For y-intercept b:

$\rm b = \dfrac{\sum y -m \sum x}{n}$

After calculating:

b = -4166040

The line becomes:

y = 2100x -4166040

If x = 2025 put this value in the line, we get:

y = 86460

Thus, the line of the best fit is y = 2100x -4166040 and the number of bottles is, 86460 which expect to sell in 2025
