Use the table of values you made in part 4 of the example to find the limiting value of the average rate of change in velocity.
A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 10.7 gallons. What is the average rate of flow of the gasoline into the gas tank?

The accompanying table shows time-to-speed data for a particular car accelerating from rest to 130 mph. How far had the car traveled by the time it reached this speed? (Use trapezoids to estimate the area under the velocity curve. Notice that intervals vary in length.) Speed change Zero to 30 mph 40 mph 50 mph 60 mph 70 mph 80 mph 90 mph 100 mph 110 mph 120 mph 130 mph Time (sec) 2.2 3.5 5.1 6.8 9.0 11.7 14.5 18.1 23.0 28.9 40.1 The car will travel ft by the time it reaches this speed. (Round the final answer to three decimal places as needed. Round all intermediate values to five decimal places as needed.)
K The following data represent the muzzle velocity (in feet per second) of rounds fired from a 155-mm gun. For each round, two measurements of the velocity were recorded using two different measuring devices, resulting in the following data. Complete parts (a) through (d) below. Observation 1 5 6 O A B 2 3 4 792.5 792.5 792.8 792.5 790.1 794.8 800.0 791.4 802.0 790.1 793.9 794.3 a) Why are these matched-pairs data? OA. All the measurements came from rounds fired from the same gun. OB. Two measurements (A and B) are taken on the same round. OC. The measurements (A and B) are taken by the same instrument. OD. The same round was fired in every trial. CHECEND b) Is there a difference in the measurement of the muzzle velocity between device A and device B at the α = 0.01 level of significance? Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. P
