Problem Solving and Data Analysis-New Redesigned SAT
- A student creates an equation to estimate his GPA based on his SAT score. Even with an SAT score of 0, the student still has a baseline GPA of 2.4. As his SAT score increases by 4 points, his GPA increases by 3.2 points. Choose the equation that best models this situation
A) SAT= 2.4+(3.2)GPA
B) SAT= 0.8+(2.4)GPA
C) GPA=0.8+(2.4)SAT
D) GPA=2.4+(0.8)SAT
E) SAT=2.4+(0.8)GPA
- What type of graph would the equation in the previous problem represent?

D) Negative exponential
E) None of the above
- Samuel is trying to model a linear relationship between the hours of homework he does each night (H) and his grades in school (G). He finds that when he does not study at all, he still has an average of 65. Even though he realizes this, he wants to do better and thinks that spending more hours doing homework every night will improve his grades. He eventually discovers that spending 5 hours per night on homework results in an average of 95 in school. Find the equation for this situation.
A) 5G-H=95
B) 4G-6H=120
C) G-5H=65
D) 2G-12H=130
E) 6G-5H=95
- How much would the slope change if 5 hours of studying only gave Samuel an average of 80?
A) The slope would increase by 3
B) The slope would be doubled
C) The slope would be halved
D) The slope would decrease by 4
E) The slope would increase by 4
- Many economists think that the price of oil is inversely related to stock prices. Suppose that the stock market has a base value of 5,000 points even when oil is free or the price of oil is zero.

Which of the following describes the change in the graphical representation of stock market value and oil prices?
A) The y-intercept would increase by 150%
B) The y-intercept would decrease by about 66%
C) The slope would decrease
D) Both b and c
E) Both a and c
