A line of best fit for this data is C = 51m + 4.4, where Cis the cumulative cell phone cost and m is the number of months.
Using this data, which value is the best prediction of the cumulative cell phone cost after 18 months?

Answer :

Answer:

cumulative cell phone cost after 18 months = 922.4

Step-by-step explanation:

We are given the line of best fit for the data as;

C = 51m + 4.4

where;

C is the cumulative cell phone cost

m is the number of months.

Now, we are told that m = 18 months

Thus;

C = 51(18) + 4.4

C = 918 + 4.4

C = 922.4

Tthe best prediction of the cumulative cell phone cost after 18 months is 922.4

Given the equation for the line of best fit expressed as C = 51m + 4.4,

where

C is the cumulative cell phone cost

m is the number of months.

We need to predict the cost after 18 months. Substitute m = 18 into the function to get C

C = 51m + 4.4

C = 51(18) + 4.4

C = 918 + 4.4

C = 922.4

Hence the best prediction of the cumulative cell phone cost after 18 months is 922.4
