Playing video games makes Matt so happy that he thinks it even helps him complete more schoolwork. Matt's roommate Gabriel is skeptical, so over the next few days, Gabriel asks Matt about his progress on his daily reading. For each day, Gabriel notes the number of minutes Matt spends playing video games, x. He also takes the number of pages Matt reads and divides it by the total number of pages assigned, y.
The least squares regression line of this data set is:
Y = -0.355x + 69.402
Complete the following sentence:
If Matt spends an additional minute playing video games, the least squares regression line predicts his completion percentage drops by points.
What goes into the blank?

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?
