relates the variables x and y, the overall dimensions.
(b) Write an equation, based on the total area, that also x
relates the variables x and y.
(c) Solve the system of equations that you created in (a) and (b) algebraically to find all possibilities for the

Patricia and Whitney began arguing about who did better on their tests, but they couldn’t decide who did better given that they took different tests. Patricia took a test in English and earned a 76.5, and Whitney took a test in Math and earned a 64.5. Use the fact that all the students’ test grades in the English class had a mean of 73.1 and a standard deviation of 10.5, and all the students’ test grades in Math had a mean of 60.9 and a standard deviation of 10.7 to answer the following questions.

a. Calculate the Z-score for Kimberly’s test grade.
b. Calculate the z-score for Karina’s test grade.
c. Which person did relatively better?
