A zoologist studied the running speeds of animals in terms of the animals' body lengths. The results of the study are shown in the following table. (A graphing calculator is recommended.) Body Length (In centimeters), x 15 16 24 25 60 Running Speed (In meters per second), y 1 2.5 7.5 5 7.4 7.6 20 (a) Use the points (9, 2.5) and (60, 20) to find a linear model that will predict the running speed y (in m/s) of an animal with a body length of x centimeters. (Round your coefficients to three decimal places.) y (b) Use your linear model to estimate the expected running speed of an animal whose body length is 54 centimeters. Round to the nearest tenth of a meter per second. m/s Need Help? Read It Watch It
