the following table shows the test scores and sleep averages of several students. hours of sleep (x) 7 7 7 6 8 8 9 5 6 7 7 9 8 8 10 8 test score (y) 90 75 70 70 85 95 90 60 65 80 70 85 85 100 95 90 (a) use graphing technology (ti calculator or desmos) to find the linear regression equation that models the data. let x equal the hours of sleep and y equal test score. explain the steps you use. (b) use the equation to determine the approximate test score of a student who sleeps an average of 7.5 hours a night. show your work

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
