Your teacher surveyed the class to determine the number of hours that each student spent on social media. Your teacher created a table and scatterplot graph that displayed the number of hours x and the average final grade percentage y based on the hours. Using the equation of the trend line of tje data y = 7.2x + 98.9 predict the average final grade percentage to tje nearest whole number if a student spent 10 hours on social media
To make the prediction, we substitute x = 10 into the given equation:
y = 7.2x + 98.9
y = 7.2(10) + 98.9
y = 72 + 98.9
y = 170.9
Therefore, if a student spent 10 hours on social media, the predicted average final grade percentage would be approximately 171.
To predict the average final grade percentage if a student spent 10 hours on social media, you can use the equation of the trend line provided: y = 7.2x + 98.9.
Substituting x = 10 into the equation, we get:
y = 7.2(10) + 98.9
y = 72 + 98.9
y = 170.9
Rounding the average final grade percentage to the nearest whole number, the predicted value would be 171. Therefore, if a student spends 10 hours on social media, the predicted average final grade percentage would be approximately 171.
