Increasing numbers of manatees ("sea sirens") have been killed by boats off the Florida coast. The following graph shows the relationship between the number of boats registered in Florida and the number of manatees killed each year.t 100, 80 60 40 20 6. 8 Boats (100,000) The regression curve shown is given by f(x) = 3.55x2 - 30.2x + 81 manatees (4.5 s xs 8.5), where x is the number of boats (in hundreds of thousands) registered in Florida in a particular year and f(x) is the number of manatees killed by boats in Florida that year. (a) Compute the average rate of change of f over the intervals [5, 6] and [7, 8]. rate of change over [5, 6] = manatee deaths per 100,000 boats rate of change over [7, 8] = manatee deaths per 100,000 boats (b) What does the answer to part (a) tell you about the manatee deaths per boat? O More boats result in less manatee deaths per additional boat. O More boats result in more manatee deaths per additional boat. Manatee deaths

For the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year spam.The following ordered pairs shows dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span, (number of units sold, profit) for specific recorded years: (46,600),(48,550),(50,505),(52,540),(54,495). Use linear regression to determine a function Pwhere the profit in thousands of dollars depends onthe number of units sold in hundreds.
