The data for numbers of times per week 18 students at Whackamole High eat meat are shown below: dotplot shows 2 points above 4, 4 points above 5, 5 points above 6, 4 points above 7, and 3 points above 8.

Part A: Describe the dotplot. (4 points)

Part B: What, if any, are the outliers in these data? Show your work. (3 points)

Part C: What is the best measure of center for these data? Explain your reasoning. (3 points) (10 points)

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
