Answer: 12.5

Step-by-step explanation:

So, basically there is 5 minutes and the number of times occuring is 5 so its 5x1 which is 5 and then there is 10 minutes and the number of times occuring  is twice so its 2x10 which is 20. Next, is 15 minutes and the times occuring  is 2 so, 2x15 which is 30. And finally theres  20 minutes and the amount of times occuring  is once so 20x1 which is 20. Then you add them all up which is 5+20+30+20=75. And the formula for mean/average is The sum of all number/ The amount of numbers there are so 75/6 is 12.5.

How to find missing angles​
aliina [53]

To determine to measure of the unknown angle, be sure to use the total sum of 180 degrees. If two angles are given, add them together and then subtract from 180 degrees. If two angles are the same and unknown, subtract the known angle from 180 degrees and then divide by 2.
