Concept explainers
All of the following exercises can be done with a graphing calculator if your instructor so directs. The calculator can also be used to check your work.
Stock prices. The data in the following table give the price of one share of Starbucks stock on January 1of various years (see Exercise 20 Section R6)
Number of years, x, since 2010 | Price of one share of Starbucks stock on January 1 |
0 | $20.59 |
1 | $30.21 |
2 | $46.61 |
3 | $55.39 |
4 | $76.17 |
a. Find the exponential regression curve,
b. Use the regression curve to estimate the price of one share of Starbucks stock on January 1 in 2016 and 2020.

- Running In 1987, Canadian Ben Johnson set a world record in the 100-m sprint.The record was later taken away when he was found to have used an anabolic steroid to enhance his performance. His speed at various times in the race is given in the following table . Source: Information Graphics. Timesec Speedmph 0 0 1.84 12.9 3.80 23.8 6.38 26.3 7.23 26.3 8.96 26.0 9.83 25.7 a. Use the information in the table and left endpoints to estimate the distance that Johnson ran in miles. You will first need to calculate t for each interval. At the end, you will need to divide by 3600 the number of seconds in an hour, since the speed is in miles per hour. b. Repeat part a, using right endpoints. c. Wait a minute, we know that the distance Johnson ran is 100m. Divide this by 1609, the number of meters in a mile, to find how far Johnson ran in miles. Is your answer from part a or part b closer to the true answer? Briefly explain why you think this answer should be more accurate. d.arrow_forwardUsing your graphing calculator, make a scatter plot of the data from the table. Then graph your model from Question 2 along with the data. How well does your model fit the data? What could you do to try to improve your model?arrow_forward
