A driver’s age has something to do with his or her chance of getting 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-year-old Americans have driven a total of 100 million miles, approximately 4 have been in accidents in which someone died. Source: Insurance Institute for Highway Safety The number of fatal vehicle crashes per 100 million miles, y, for drivers of age x can be modeled by the formula y=0.013 x^2-1.19 x+28.24 Use the formula above to solve Exercises 141-142 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?
