Question

Use the model to find the expected number of automobile registrations (in millions) for the year 2006.

Express your answer as a decimal rounded to the nearest hundredth. Do not include units with your answer.

Answer 1

The expected number of automobile registrations for the year 2006 is 13.47

Using the equation of the line :

• y = 0.3949x - 778.7

Substitute x = 2006 into the equation :

y = 0.3949(2006) - 778.7

y = 792.1694 - 778.7

y = 13.4694

Rounding to the nearest hundredth, the expected number of automobile registrations for the year 2006 is 13.47
