Answer:11
The mean change in points per minute would be 11. which means you would have lost 11 points every minute.
What are mean?
The mean is the average value which can be calculated by dividing the sum of observations by the number of observations
Mean = Sum of observations/the number of observations
We have been given that You play a video game for 15 minutes. and lose 165 points.
We need to find the mean change in points per minute;
Mean = the lose point/ duration of video game
Mean = 165 / 15
MEan = 33/3
Mean = 11
Therefore, the mean change in points per minute would be 11. which means you would have lost 11 points every minute.
