(z=-3) and (z=7)
6z-4z-z = 6-7-4 z = -5
If 3z/2 = 9 then the value of z is 6
If Z = 3, then (9 + 7Z) = [ 9 + 7(3) ] = 9 + 21 = 30
The formula for Z obtained is zobt equals the average of the sample (Xbar)minus the average of the population (u), divided b the standard deviation of the sample (s), divided be the square root of N. Example: Zobt= X-u ,divided by s ,divided by ,square root of N
z/7 + 5 = 12 z/7 = 12 - 5 = 7 z = 7 x 7 = 49
2+2+7=11 K?
Z=z
Z=153.
z equals 7
z / (1/7) = 7z.
(z=-3) and (z=7)
4
If you mean: (3z/7) +9 = -7 then the value of z works out as -37 and 1/3
89
x equals 7
z = -1/7
