what is the average of 132,145,140,128? do u add them all togher then divide ? or just add them and get the answer?
To get the mean (arithmetic average), add all the scores and divide by the number of scores.
I hope this helps. Thanks for asking.
We add all the numbers given.
132 + 145 + 140 + 128 = 545
You were given 4 THREE-DIGIT numbers.
The sum is 545.
We now divide 545 by 4.
Average = 545/4
Average = 136.25
To find the average of a set of numbers, you need to add them together and then divide the sum by the total number of values in the set. So, in this case, you would add together the four numbers: 132 + 145 + 140 + 128 = 545.
Then, to find the average, you would divide the sum by the total number of values, which is 4 in this case. So, 545 ÷ 4 = 136.25.
Therefore, the average of 132, 145, 140, and 128 is 136.25.
