Does anyone know how to do this

The answers are given below.

Step-by-step explanation:

1. There is a correlation between shoe-size and reading ability.There is probably also causation. This is because there is an increase in reading ability with increase in shoe-size

2.There is no correlation between amount of cereals bought and amount of milk purchased.

3.There is no correlation between height and  number of points scored.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the answer will be b x² +x-1
