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

Answer 1

10.71 Million

Explanation:

The given model is y = 0.3949 * x - 778.7, where y is the expected number of automobile registrations in millions and x is the year. To find the expected number of automobile registrations for year 1999, we would set x = 1999. Plugging this into the model, we get y = 0.3949 * 1999 - 778.7 = 10.7061. Rounding to the nearest hundredth, we get y = 10.71. Therefore, the expected number of automobile registrations for year 1999 is 10.71 million.
