Answer: John’s average test score is 90.

Step-by-step explanation:

To find the average of a set of numbers, we must find the sum of all of the numbers (add them together) and then divide by the amount of numbers in the set. In this case, we begin by finding the sum of the four numbers:

69 + 86 + 100 + 105

= 360

Then, we divide by 4, since there are 4 scores in the data set.

360/4 = 90

Therefore, John’s average test score is 90.

Hope this helps!

Basically, someone would theoretically roll each number 100 times out of 600. Because there are two numbers on the dice greater than 4, multiply 100 by 2 to find the answer.

I tried my best, and I don't know if they wanted you to use pi or 3.14 so I hope this is correct :]
