Answer:
The mean number of minutes Janelle spent on homework per day is 55 minutes.
Step-by-step explanation:
To find the mean (average) number of minutes Janelle spent on homework per day, you sum up all the numbers and then divide by the total number of days.
Mean = Sum of values/Number of values
Let's add up the numbers Janelle wrote down:
30 + 45 + 95 + 0 + 10 + 45 + 60 + 75 + 90 + 100 = 550
Now, divide this sum by the total number of days (which is 10):
Mean = 550/10 = 55
So, the mean number of minutes Janelle spent on homework per day is 55 minutes.
