Question

I need the answers with a explanation how you got it

Answer 1

In the question, we are given the table of values below.

Using the graph plotter,

The slope(m) and the intercept(c) is given as (nearest tenth)

`m=14.0\text{ and c =}478.7`

This can be inserted into the equation of best fit below

`y=14.0x+478.7`

Also, the correlation coefficient is given as

`r=1.0`

The relationship is also strong and positive
