mean = (9+3+8+10+12+6)/6
= 48/6
= 8
To find the mean you first have to add up all the numbers then you divide it by how many numbers you have and you got the mean. Example: 12+13+5=30 30/3=10 10 is the mean
You can select 12 numbers for the first digit, 11 numbers for the second digit, and 10 numbers for the third digit; so 12*11*10 = 1320 sets of 3 numbers can be made out of 12 different numbers.

There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42
3+7=10 10+2=12 12*2=24

They are all positive numbers.
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

(6 + 12 + 10 + 4 + 3) ÷ 5 = 7 Therefore, 7 is the average of the five numbers given in the question.
Add all the numbers up and divide by how many there are... Example: 10,11,12 add them up: 10+11+12= 33 then divide by how many numbers there are... 3 33/3 = 11
13.67mean = (12 + 13 + 17)/3= 41/3= 13.67
