What is the formula for x-bar in statistics?
(x value) - average
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.
What does quadratic formula find?
When an equation cannot be solved for "x" to find the zeroes, the quadratic formula can be used instead for the same purpose.
What does x mean in a math equation?
x is a variable. You do not have to know what its value is. In that equation you have to find the value of x, so if you already know what x stands for then you know the answer

What the formula of a parellelogram to find the value of x?
It depends on what x is - an angle, a side, a diagonal, etc
What is the formula for relative error?
The formula for relative error is:Erel= |x-x*| / |x|, where x is the proper value, and x* an approximate value.
What formula can be used to find 2x - 5 and 5x - 1?
You don't need a formula. All you need is the value of 'x'.

How value of x can be calculated in the formula Na2CO3?
With great difficulty - since there is no x in Na2CO3.
What is the formula to find a length that is twice as much as the width that gives you a certain area?
The formula for Area is A = L x W. To solve the above problem, let X represent the width and 2X represent the length. Use the formula to find the value of X: A = 2X x X. Since the "certain area" is known, use that number as A (we'll use 200 sq ft as an example): 200 = 2X x X; rewrite as 200 = 2X-squared; next, divide both sides of the equation by 2: 100 = X-squared; find the square root of 100 to find the value of X; now the equation is 10 = X. Remember X represents the width, so the width is 10. The length is twice the width, so 10 x 2 = 20.
