Your teacher surveyed the class to determine number of hours at each student's been on social media your teacher created a table and scatterplot graph that displayed the number of hours x at the average final grade percentage why based on the hours using the equation of the trend line of the data y = -7.2x + 98.9 predict the average final grade percentage to the nearest whole number if the students spent 10 hours on social media
To predict the average final grade percentage if a student spent 10 hours on social media, we can use the given equation:
y = -7.2x + 98.9
Substitute x = 10 into the equation:
y = -7.2(10) + 98.9
y = -72 + 98.9
y = 26.9
Therefore, if a student spent 10 hours on social media, the predicted average final grade percentage is 27%.
