A baseball is thrown into the air from a height of 5 feet. The ball reaches a maximum height of 43.5 feet and spends a total of 3.2 seconds in the air. Which equation models the height of the baseball? Assume that acceleration due to gravity is –16 ft/s2. h(t) = 16t2 49.64t 5 h(t) = -16t2 5t 49.64 h(t) = -16t2 49.64t 5 h(t) = 16t2 5t 49.64

Heights of men on a baseball team have a bell-shaped distribution with a mean of 177 cm and a standard deviation of 6 cm. using the empirical rule, what is the approximate percentage of the men between the following values? a. 159 cm and 195 cm b. 165 cm and 189 cm a. 89% of the men are between 159 cm and 195 cm. (round to one decimal place as needed.) b. 89% of the men are between 165 cm and 189 cm. (round to one decimal place as needed.)
