It depends on what average you want to find.
To find the mean of 81, 81, 98, and 91 add the numbers together and divide by 4 (the number of numbers you added).
81 + 81 + 98 + 91 = 351
351 divided by 4 = 87.75.
To find the median, list the numbers in order and find the one in the middle.
81, 81, 91, 98
81 and 91 are in the middle.
To find the mode, look for the number that appears the most,
81 appears twice and the other numbers appear once.
81 is the mode.
98
The average is 72. To compute the average, you add up the numbers and then divide by the amount of numbers you have. So, in this case: 0 + 84 + 87 + 91 + 98 = 360 360 divided by 5 = 72
To find the median of a set of numbers, you first need to arrange them in numerical order. Once you have them in order, the median is the middle number. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers. In this case, the numbers arranged in numerical order are: 78, 81, 82, 88, 88, 88, 89, 91, 91, 92, 93, 94, 95, 96, 98. Since there are 15 numbers, the median will be the 8th number, which is 89.

The median is 82.
The average is 72. To compute the average, you add up the numbers and then divide by the amount of numbers you have. So, in this case: 0 + 84 + 87 + 91 + 98 = 360 360 divided by 5 = 72

Between 81 and 115 pounds. Average weight: 98 pounds.

A 91 engine will not fit in a 98 Escort. The 91 engine is from a generation II Escort whereas a 98 engine is from a generationIII Escort.
number of composite numbers between 81 and 100 = 15composite numbers between 81 and 100 = 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99
The GCF is 7.
The next test must be a grade of 98. You find this by multiply 4 by 88 and subtracting this from 5 multiplied by 90. This is 450 - 352, or 98.
