The mean is the is the total of the numbers and then dividing by how many numbers.
Work with the total sums of the numbers:The mean of eight numbers is 41, so the total of those eight numbers is 8 x 41 = 328The mean of two of those eight numbers is 29, so the total of those two numbers is 2 x 29 = 58So the total of the other six numbers must be the difference between these two totals, that is 328 - 58 = 270Thus the mean of these six numbers is their total divided by 6, namely 270 ÷ 6 = 45.
Any one of the numbers is equal to the mean of the set.
the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
What you have to do is you add up all the numbers then you divide by the number of numbers. ex. Say you have the numbers 45,56,39 and 35 you add them all up 45+56+39+35=175 then you divide 175/4(because there is 4 numbers)=43.75
