When calculating mean, you sum every number in some data set and divide by how many numbers are in the set.
For every zero added to the data, the sum doesn't change but the number which you divide the sum by increases by one.
For example, if your homework grades in a class are:
82, 76, 90, 85, 92
Your mean homework grade then is
(82 + 76 + 90 + 85 + 92) / 5 = 425 / 5 = 85
Say you forget to do your next homework assignment, so you get a zero. To calculate your new mean grade, instead of adding up the numbers again, just increase the denominator by one:
425 / (5 + 1) = 425 / 6 = about 71

How do you solve 24x2-29x equals 0?
First, factor it out. This would first look like x(24x-29)=0, which would mean that x=0 or 29/24.

How do you solve a mean squared deviation?
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
W to the third power plus 27 equals?
Well if you mean you have to solve w^3+27 then I guess make it = 0 then solve it w^3+27=0 -27 w^3=27 3rd root w=-3 ~¤~Amy~¤~
