The mean is 8 because: (1+6+10+11+12)/5=8
We know that the Arithmetic Mean of a data set = (sum of all the items)/ number of items.
=(1+6+10+11+12)/5
=(40)/5
=8.
The Arithmetic Mean of 1, 6, 10, 11, and 12 is 8.
(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12
12
(11/12) / (1/11) = (11/12) x (11/1) = 121/12 = (10 and 1/12) = 10.08333 of them (rounded)
The mean is the sum of the values divided by the number of values. In this case (12+10+19+8+2+15+1+20+6+11+3+7)/12 = 9.5.

If you mean -3a = 10-11 then a = 1/3
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
10
11 is closer to 10 than to 12. This is because the distance between 11 and 10 is 1 unit, while the distance between 11 and 12 is 1 unit as well. When comparing distances on a number line, we look at the absolute value of the differences between the numbers. In this case, |11-10| = 1 and |11-12| = 1, but 11 is on the left side of 12, making it closer to 10.
