What is the formula for z scores?
Z = (x minus mu) divided by sigma.
What is the quadratic root of z squared plus 9z plus 18 equals 0?
use the quadratic formula. when done so the roots are z=-3, and z=-6
How do I find the Z score for tests with mean of 100 and a standard deviation of 20?
Z = (x-mu)/sigma. So, for your example, any x value can be transformed to Z-score by the formula Z = (x-100)/20.
X y - z when x 783 y 472 z 322?
Answer : 369,254. If you are multiplying X and Y, then subtracting Z. So your formula should look like: (XY) - Z. Where, X = 783, Y = 472, and Z = 322 So that, X times Y is used to subtract Z. You should get 369,254.
What is the formula for calculating the depth of liquid in a sphere?
Consider a sphere of radius r. Let the z-axis be the vertical axis and suppose the sphere's centre is at z = 0. [Thus the sphere goes from z = -r to z = r.] Suppose the volume of liquid in it is V. Then you need to sove 3V/pi = 3r2z - z3 + 3r3 - r3 = 3r2z - z3 + 2r3 for z. Then, the depth is z + r
What is the formula for the volume of a pizza?
If the height (thickness) of the pizza is a, and the radius is z, then the formula is pi*z*z*a.
What it the formula of juice?
Its Formula cannot be obtained because it is a mixture
What is the Z score formula for statistics?
z=x-mean / sd
What is the formula for z scores?
Z = (x minus mu) divided by sigma.
What is the dimensional formula of theory of relativity?
I*I = x*x + y*y + z*z - t*t
What is the formula to convert a z score into a percentile rank?
You need to look up z-score tables.
What is the empirical formula of C3H6O3?
The empirical formula of C3H6O3 is CH2O. This is obtained by dividing the subscripts in the molecular formula by the greatest common factor.
What is the answer to 4z squared minus 16z minus 18?
Using the quadratic formula you get z≅4.91547594742265 or z≅-0.91547594742265
What is the distributive formula?
Distributivity is a property (not a formula) of two operators over a set. The distributive property of multiplication over addition states that, if x, y and z are any three numbers, then x*(y + z) = x*y + x*z
Why are complex numbers useful in today's society?
1. A complex formula like (z+1/z) is used to study and design airplane wings. 2. I use complex numbers to make math related art. The LINK below shows artwork based on the formula (z-1)/(z+i)

Is it true that z values have no units of measurements?
It is true; the z value has no unit of measurement. The formula for z is: (x-mu)/sigma and the units in the numerator and denominator cancel out.
