Avreage = Sum/number of values
So 10 = sum/2
Multiply both sides by 2: 20 = sum
Sum of 5 numbers with an average of 10 = 50
10 and 8
split 10 in two parts such that sum of their squares is 52. answer in full formula

The two numbers are 10 and 4
Assuming mean average: average = sum/number_of_items → 10 = sum/2 → sum = 10 x 2 = 20 So any two numbers with a sum of 10 have a mean average of 10, eg {5, 15}, {1, 19}, {0, 20}, {-5, 25}, etc. With the median average, for two numbers it is exactly the same as the mean average, so any pair of numbers that sum to 20 will do. With the mode average, only the case of the pair of numbers {10, 10} will suffice.
Add the numbers together (sum) and divide by two (average). SUM: 2 + 8 = 10 AVG: 10 / 2 = 5
The sum of the first 10 natural numbers is 51, with an average of 5.1
Sum of 5 numbers with an average of 10 = 50
To find the average of a set of numbers, you add all the numbers together. Then you divide this sum by the size of the set - for instance, if you have 10 numbers, you divide the sum by 10.
Sum of numbers = 40 Count of numbers = 4 Average = Sum/Count = 40/4 = 10
10 and 8
split 10 in two parts such that sum of their squares is 52. answer in full formula
Add the numbers then divide the sum by the number of numbers you added e.g. average of 1,2,3,4 four numbers add em up 1+2+3+4 =10 divide the sum by the number of numbers 10/4 average of 1,2,3,4 is 2.5
