Chapter 1, Problem 135

(choose chapter or problem)

A drivers age has something to do with his or her chance of gettinginto a fatal car crash. The bar graph shows the number of fatalvehicle crashes per 100 million miles driven for drivers of variousage groups. For example, 25-year-old drivers are involved in4.1 fatal crashes per 100 million miles driven. Thus, when a groupof 25-year-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 crashes per 100 million miles, N, fordrivers of age x can be modeled by the formulaN = 0.013x2 - 1.19x + 28.24.Use the formula to solve Exercises 135136.What age groups are expected to be involved in 3 fatalcrashes per 100 million miles driven? How well does theformula model the trend in the actual data shown in the bargraph?
