Operating Expenses The operating expenses of Amazon increased from $3.6 billion in 2008 to $16.3 billion in 2012.50 a. Use this information to find a linear model for Ama- zon's operating expenses E (in billions of dollars) as a function of time t in years since 2010. b. Give the units of measurement and interpretation of the slope. c. Use the model from part (a) to estimate the 2011 oper- ating expenses. (The actual 2011 operating expenses were $10.9 billion.)

Demand for Candy Bars In this problem you will determine a linear demand equation that describes the demand for candy bars in your class. Survey your classmates to determine what price they would be willing to pay for a candy bar. Your survey form might look like the sample to the left. a Make a table of the number of respondents who answered yes at each price level. b Make a scatter plot of your data. c Find and graph the regression line y=mp+b, which gives the number of respondents y who would buy a candy bar if the price were p cents. This is the demand equation. Why is the slope m negative? d What is the p-intercept of the demand equation? What does this intercept tell you about pricing candy bars? Would you buy a candy bar from the vending machine in the hallway if the price is as indicated. Price Yes or No 50 75 1.00 1.25 1.50 1.75 2.00
Neurology The average weight of a male child’s brain is 970 grams at age 1 and 1270 grams at age 3. (a) Assuming that the relationship between brain weight y and age t is linear, write a linear model for the data. (b) What is the slope and what does it tell you about brain weight? (c) Use your model to estimate the average brain weight at age 2. (d) Use your school’s library, the Internet, or some other reference source to find the actual average brain weight at age 2. How close was your estimate? (e) (d) Do you think your model could be used to determine the average brain weight of an adult? Explain.
The median home value in Michigan and New York (adjusted for inflation) are shown below. Year Michigan New York 1950 45400 61500 2000 115600 148700 If we assume that the house values are changing linearly,a) In which state have home values increased at a higher rate? New York, Mich., or equal rates: b) If these trends were to continue, what would be the median home value in Michigan in 2010?$ :c) If we assume the linear trend existed before 1950 and continues after 2000, the two states' median house values will be (or were) equal in what year? (The answer might be absurd)The year :
32. The table below gives the percentage of males (age 65 or older) that are a part of the workforce. Year (let t = 0 be 1900) Percentage of males 1952 31 1990 20 2010 (predicted) 18 your answers to the nearest hundredth. Use all three data points to get the linear equation of best fit. You will need to use the 102N Excel sheet or a graphing calculator to answer the problem. The y-intercept means that in the year_____ the percentage of males that are part of the work force will be ----------- percent. The slope means that each year the percentage of males in the work force is going down by ______ percent.
