Question 1065879
The number of fatalities per 100 million vehicle miles driven is approximately 
N(x) = 0.0336x^3 − 0.118x^2 + 0.215x + 0.7 (0 ≤ x ≤ 7) 
where x denotes the age group of drivers, with x = 0 corresponding to those aged 50-54, x = 1 corresponding to those aged 55-59, x = 2 corresponding to those aged 60-64, . . . , and x = 7 corresponding to those aged 85-89. 
What is the fatality rate per 100 million vehicle miles driven for an average driver 
In the 50-54 age group?:: N(0) = 0.7 
In the 85-89 age group?:: N(7) = 7.9478
