The number of fatalities due to car crashes, based on the number of miles driven, begins to climb after the driver is past age 6

andriy [413]

Answer:

The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 50-54 age group is 0.7.

The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 60-64 age group is 3.3268.

Step-by-step explanation:

The number of fatalities per 100 million vehicle miles driven is approximately given by the following function:

$N(x) = 0.3336x^{3} - 0.118x^{2} + 0.215x + 0.7$

In which x corresponds to the age group.

What is the fatality rate per 100 million vehicle miles driven for an average driver in the 50-54 age group?

This is N(0), since $x = 0$ represents those aged 50-54.

So:

$N(x) = 0.3336x^{3} - 0.118x^{2} + 0.215x + 0.7$

$N(0) = 0.7$

The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 50-54 age group is 0.7.

In the 60-64 age group?

This is N(2), since $x = 2$ represents those aged 60-64.

$N(x) = 0.3336x^{3} - 0.118x^{2} + 0.215x + 0.7$

$N(2) = 0.3336*2^{3} - 0.118*2^{2} + 0.215(2) + 0.7 = 3.3268$

The fataly rate per 100 million vehicle miles driven is approximately for average driver in the 60-64 age group is 3.3268.
