First, we substitute x = 5 into the equation y = 7 + 2.6x
y = 7 + 2.6(5)
y = 7 + 13
y = 20
Therefore, it should take 20 minutes to fall asleep for someone who watched a screen for five hours throughout the day.
The correct answer is 20 minutes.
A statistician develops a model to determine how many minutes it will take an individual to fall asleep given the number of hours they spent looking at a screen throughout the day. Using their model, y=7+2.6x
