2 and 5 2 and 10 5 and 10
Add up all the numbers together and then divide by 12 to find the average mean:- 68/12 = 17/3 or as 5 and 2/3
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
An average person could commit to memory around 10-15 phone numbers.
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 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
To find the average of a group of numbers, add together all the numbers and divide by the number of numbers you have added together. In this instance, 6 + 10 = 16 / 2 = 8.
There is not enough information. For example, 2 numbers, whose average is 10 could be -50 and 70 or 10 and 10 or 9 and 11 or 7.5 and 12.5 etc. All that you know in this case is that the sum of the two numbers = average*number of values = 10*2 = 20
Sum of numbers = 40 Count of numbers = 4 Average = Sum/Count = 40/4 = 10
Add the numbers together (sum) and divide by two (average). SUM: 2 + 8 = 10 AVG: 10 / 2 = 5
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
The average is 9.66... recurring.
The halfway point between two numbers is found by taking the average of the two numbers. In this case, the average of 10 and 90 is (10 + 90) / 2 = 50. Therefore, the number halfway between 10 and 90 is 50.
The term average (which can also be referred to as the mean) is where you add all of the numbers in a set and divide by how many numbers there are. For example, the average of 2, 3, 5, and 6. First, add all of the numbers. 2+3 = 5 5+5 = 10 10+6 = 16 or... 2+3+5+6 = 16 Lastly, you divide by the amount of numbers in the set. In this example, there are four numbers. Now, you divide by the total by the amount of numbers. 16/4 This equals 4, and you have your average (or mean)!
That would be the average of those two numbers.The average of two numbers is half of their sum.1/2 (-10 + 6) = 1/2 (-4) = -2
