Question

#3 A keyboarding instructor at a community college collected data comparing a student's age and their typing speed. The equation for the line of best fit is given as y = -1.4x + 117.8, where x is the "age in years" and y is the "typing speed. If you are 25 years of age, what is your typing speed?

Answer 1

82.8

Explanation:

In the above question, we are given the following information:

The equation for the line of best fit is given as y = -1.4x + 117.8, where

x is the "age in years"

y is the "typing speed. If you are 25 years of age, what is your typing speed?

This is calculated as:

y = -1.4x + 117.8

x = 25 years

y = -1.4(25) + 117.8

y = -35 + 117.8

y = 82.8

Hence, If you are 25 years of age, what is your typing speed is 82.8
