Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
Now that you know how to find the average—in other words,how to calculate the mean of a given set of data—it’s time to test what you’ve learned. In this section, we'll give you four math questions that involve finding or using the mean. The first two questions are our own, w...
So does that mean that d/dx of the integral from -pi/2 to x of sqrt(cost)dt = sqrt(cosx)? Yep. JJ6 said: Does the -pi/2 just disappear because it is a constant? Disapear from where?FAQ: What is the formula for finding arclength when given an integral? What...
Formula for finding the z-score Every normal random variable X can be transformed into a z score. The formula used for this purpose is – z = x- μ where x is a normal random variable, μ is the mean of X, and σ is the standard deviation of X. let us now understand the standar...

What is the formula for finding the inverse of a matrix? The formula is given by 1 upon the determinant of the matrix multiplied by the adjoint of the matrix. The adjoint of the matrix is given by the transpose of the matrix of cofactors. ...
this is the basic formula for finding the standard deviation for a given set of data. standard deviation for discrete data for discrete frequency distribution of the type: the standard deviation is given as: where x̄ is the mean of the distribution and standard deviation for continuous ...
In this work, the GB02 analysis is first revisited, showing that GB02 employed several ad hoc scaling assumptions for the turbulent kinetic energy dissipation rate and, although implicitly, for the mean velocity gradient adjacent to the roughness elements. The similarity constants arising from the ...
Instead of using the formulae above to find the covariance, it is often easier to use the following equivalent equation based onmomentsandcross moments: Example In the previous example, after finding the expected values of and , we could have done: ...
The overall benefits of a high free cash flow, however, mean that a company can pay its debts, contribute to growth, share its success with itsshareholdersthrough dividends, and have prospects for a successful future. Disadvantages One drawback to using the free cash flow method is that capita...
