Diane is a camp counselor. She designed the obstacle course and test the course with three friends the dot plot shows the time it takes them to complete the obstacle course on the dot plot we have number 5678 9101112 and 13 there's a dot at five a dot at six a dot at 10 and it says obstacle course test time and what is the name of the times mean equals how many minutes
To find the mean of the times, we must add up all the times and then divide by the total number of times.
The times are: 5, 6, and 10.
Adding them together: 5 + 6 + 10 = 21
There are a total of 3 times, so to find the mean: 21 รท 3 = 7
Therefore, the mean time it takes to complete the obstacle course is 7 minutes.
