Question

The scatter plot shows the number of stamps Katie collected in different months:

plot ordered pairs 1, 30 and 2, 70 and 3, 110 and 4, 150 and 5, 190

What is the approximate predicted number of stamps she collected in the 25th month? (1 point)
980
990
1,000
1,010

Answer 1

Hello!

The approximate predicted number of stamps she collected in the 25th month is 990.

Explanation:

The ordered pairs are as follows:

( 1, 30), ( 2, 70), ( 3, 110), ( 4, 150), and ( 5, 190).

The pattern visible is that each month the value increases by 40 from each previous month.

The equation you would have to do in order to see how many stamps she collected is:

`30` +
`40` ×
`24=30` +
`960=990`

Hope this helps!
