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.

- What is interpolation when using a linear model?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_forwardFor the following exercises, draw a scatter plot for the data provided. Does the data appear to be linearly related? For the following data, draw a scatter plot. If we wanted to know when the population would reach 15,000, would the answer involve interpolation or extrapolation? Eyeball the line, and estimate the answer.arrow_forward
- Describe what it means if there is a model breakdown when using a linear model.arrow_forwardFor the following exercises, consider this scenario: The profit of a company decreased steadily overa ten-year span.The following ordered pairs show dollars and the number of units sold in hundreds and the profit in thousands ofover the ten-year span (number of units sold, profit) for specific recorded years: (46,250),(48,305),(50,350),(52,390),(54,410). Use linear regression to determine a function y,where the profit in thousands of dollars depends onthe number of units sold in hundreds.arrow_forwardHow does the value of a effect the graph of y = ax2? Discuss the case for a >= 1 and for 0 <= a <=1.arrow_forward
- Thanks. How do you calculate this answer using the graphing calculator instead of Excel?arrow_forwardTwo companies report a 15% gain in online sales over the last year. Suppose Company Q had 25 online sales and Company Z had 150 online sales last year. Sam says that they have the same growth while Anna says that they do not. Who is correct? Justify your answer using absolute change and percent change.arrow_forwardThe graph above shows projections for world population growth. Why do some demographers predict the HIGH world population growth rate that appears on the graph? A. The effect of lower fertility rates will result in a replacement level for the world population by 2050. B. Although the fertility rate in developing countries is decreasing, it is still at a level that will result in a global high rate of growth. C. The growth rate will balance the different fertility rates between developed and less developed nations. D. The fertility rate of developing countries and less developed countries will become the same.arrow_forward
- The graphs show the percentage of high school seniors who hadever used alcohol or marijuana. a. Use the line graph to estimate the percentage of seniors who used alcohol in 2014. b. Use the formula to determine the percentage of seniors who used alcohol in 2014. How does this compare with your estimate in part (a)? c. Use the line graph to estimate the percentage of seniors who used marijuana in 2014. d. Use the formula to determine the percentage of seniors who used marijuana in 2014. How does this compare with your estimate in part (c)? e. For the period from 1990 through 2014, in which year was alcohol use by seniors at a maximum? What percentage of seniors used alcohol in that year?arrow_forwardAustin Avenue Clothiers pays $55 each for sports coats and has a fixed monthly cost of $790. The store sells the coats for $73 each. Please show steps. (a) What is the linear cost-volume function C(x)? (b) What is the linear revenue function R(x)? (c) What is the break-even number of coats? (Round your answer up to the nearest whole number.)arrow_forwardThe graphs show the percentage of high school seniors who hadever used alcohol or marijuana. a.
