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
If you mean: x-3-4 = 0 then x = 7 I mean x + ln (x-3) - 4 =0
-23
First, factor it out. This would first look like x(24x-29)=0, which would mean that x=0 or 29/24.
If you mean: 3x+2y+6 = 0 then it is y = -1.5x-3 as a straight line equation
If you mean: 4n^2-60n+200 = 0 then the solutions are n = 10 or n = 5
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~¤~
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
Solve this problem -x squared -40x- 80 =0
If you mean 2y(2xy)(21)=7yx, then... 12y^2 -y=0 y(12y-1)=0 either y=0 or 12y-1=0, so y=1/12
