Answer: The mean is the same as the average. In order to find the mean, or average score of the two tests, you need to take the sum of the two tests, and then divide by the number of tests, which is two.We don’t know the score of the second exam. Let it = xThen we have the following equation:(88 + x)/2 = 9388 + x = 2 * 9388 + x = 186x = 186 – 88 = 98You need to score a 98 on the second test
