A driver's age has something to do with his or her chance, of gelling into a fatal car crash. The bar graph shows the number of fatal vehicle crashes per 100 million miles driven for drivers of various age groups For example. 25-year-old drivers are involved in 4.1 fatal crashes per 100 million miles driven. Thus when a group of 25-years old Americans have driven a total of 100 million miles, approximately 4 have been in accidents in which someone died. The number of fatal vehicle crushes per 100 million miles N , for rivers of age x can be modeled by the formula N − 0.013 x 2 − 1.19 x + 28.24. Use the formula to solve Exercises 135-136. What age groups are expected to be involved in 3 fatal crashes per 100 million miles driven? How well does the formula model the trend in the actual data shown in the bar graph?
