To find mean, you add up all of your data and then divide by how many numbers there are. Mean is the same thing as average.
1+3+5+7+9 = 25
25 divided by 5 (the number of numbers) equals 5. The average or mean of this set of data is 5.

To find the mean 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 1, 3, 5, 7, and 9 is 25. Since there are 5 numbers in the set, you divide 25 by 5 to get the mean, which is 5.
Well, honey, the mean of those numbers is 5. I mean, it's not rocket science - you just add 'em up and divide by how many there are. So, in this case, (1+3+5+7+9)/5 = 5. Easy peasy lemon squeezy.
The mean of the numbers 3 5 7 is 5.
If you mean points of (5, 1) and (2, -7) then the slope works out as 8/3
{ [(1+3) *5 ] +7 } /9 = 3 [4 *5] + 7 = 27 divided by 9 = 3 also [ (1+3) / (5+7) ] * 9 = 3 More complex is 13 * (5+7) - 9 = 3 with just signs : -1 -3 +5 -7 + 9 = 3
The domain of 1 3 5 5 7 7 can not be given because it is not a function.
The average or mean of 3, 5, 7, 9, and 11 is 7.
