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.

The number of fatal vehicle crashes per 100 million miles, N, for drivers of age x can be modeled by the formula

Use the formula to solve Exercise.

What age groups are expected to be involved in 10 fatal crashes per 100 million miles driven? How well does the formula model the trend in the actual data shown in the bar graph?

Throwing events in track and fi eld include the shot put, the discus throw, the hammer throw, and the javelin throw. The distance that an athlete can achieve depends on the initial velocity of the object thrown and the angle above the horizontal at which the object leaves the hand.
