To find the average of the numbers 88, 75, 92, and 85, first add them together: 88 + 75 + 92 + 85 = 340. Then, divide the sum by the number of values, which is 4: 340 ÷ 4 = 85. Therefore, the average is 85.
Sum = 678 Count = 8 So Average = Sum/Count = 678/8 = 84.75
79 is the average
88.2 is the average.
It is 89.
It is 88.9 (89*3 + 92*3 + ....... 85*1) / 11 = 88.9
The answer is 90.To find the average;Add the numbers together (92+85+91+89+93 = 450)Divide this total by how many numbers you have (450 / 5 = 90)The answer is your average or mean.
At a certain high school, the respective weights for the following subjects are: Mathematics 3, English 3, History 2, Science 2 and Art 1. What is a student's average whose marks were the following: Geometry 89, American Literature 92, American History 94, Biology 81, and Sculpture 85? ANSWER weight for math = 3=w1 weight for English = 3=w2 that for history = 2=w3 that for science = 2 =w4 that for arts = 1=w5 total of weight = w = w1 +w2 + w3+ w4 +w5 = 3+3+2+2+1=11 geometry mark = 89 American literature = 92 American history = 94 Biology = 81 sculpture = 85 so average = ((89*w1)+(92*W2)+(94*W3)+(81*w4)+(85*w5)/(w1+w2+w3+w4+w5) =((89*3)+(92*3)+(94*2)+(81*2)+(85*1)/(w1+w2+w3+w4+w5) =978/11=88.909
For 98 78 86 88 84 81 93 92 89 and 81: σ=6.2361
Y / 6 = 92 92 * 6 = Y 92 * 6 = 552 90 + 98 + 96 + 94 + 85 = 463 552 - 463 = 89 Answer: 89
The idea is to sort the numbers, and pick the number in the middle as the median. In cases like this, when you have two numbers in the middle (the size of the set is even), take the average of those two numbers.

92
92 = 81 and 102 = 100
To find the average of the numbers 88, 75, 92, and 85, first add them together: 88 + 75 + 92 + 85 = 340. Then, divide the sum by the number of values, which is 4: 340 ÷ 4 = 85. Therefore, the average is 85.
