To find the mean you would add up all the numbers 7+9+10+11+11+12 and get 60. Then divide by how many numbers you added by, in this case 6. So 60 ÷ 6 = 10. The mean would be: 10
The numbers are -12, -11, -10 and -9.
These are your 5 numbers: X X X X X the median (the middle number of a row) is 11, that means: X X 11 X X the mode (the most frequent number in a row) is 12, that means: X X 11 12 12 the mean (the average) is 10, that means: (X+X+11+12+12)/5=10 or: X+X+11+12+12=50 or: X+X=50-12-12-11 or: X+X=15 so the remaining numbers must be 15 combined, and lower then 11, that means they can be: 5 and 10 6 and 9 7 and 8 so you have 3 possible solutions: 5 10 11 12 12 6 9 11 12 12 7 8 11 12 12
10 = x 11 = xi 12 = xii
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.
8, 9, 11 and 12

Mean: 20.2222222 Median: 12 Mode: 11 Range: 79
The numbers are -12, -11, -10 and -9.
The mean (average) of those numbers is 16.
These are your 5 numbers: X X X X X the median (the middle number of a row) is 11, that means: X X 11 X X the mode (the most frequent number in a row) is 12, that means: X X 11 12 12 the mean (the average) is 10, that means: (X+X+11+12+12)/5=10 or: X+X+11+12+12=50 or: X+X=50-12-12-11 or: X+X=15 so the remaining numbers must be 15 combined, and lower then 11, that means they can be: 5 and 10 6 and 9 7 and 8 so you have 3 possible solutions: 5 10 11 12 12 6 9 11 12 12 7 8 11 12 12

10 = x 11 = xi 12 = xii
One possible set is {9, 9, 10, 11, 12, 15, 18}
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.
The integers are 10, 11 and 12.
To find the average of a set of numbers, you add all the numbers together and then divide by the total number of values. In this case, the sum of 8, 9, 10, 11, and 12 is 50. To find the average, you divide 50 by the total number of values, which is 5. Therefore, the average of 8, 9, 10, 11, and 12 is 10.
