Question

what is formula for combined HM​

Answer 1

Step-by-step explanation:

Combined Mean Formula

m = the number of items in the first set, xb = the mean of the second set, n = the number of items in the second set, xc the combined mean.

Answer 2

What is the formula for combined HM​-

• Consonant mean is a sort of normal that is determined by isolating the number of qualities in an information series by the amount of the reciprocals (1/x_i) of each worth in the information series. ... It is the most fitting measure for proportions and rates since it levels loads of every information point.

• A Harmonic Progression (HP) is characterized as a grouping of genuine numbers not entirely settled by taking the reciprocals of the math movement that doesn't contain 0. In symphonious movement, any term in the succession is considered as the consonant method for its two neighbors. Now, the grouping a, b, c, d, … is considered as a number juggling movement; the symphonious movement can be composed as $\frac{1}{a}$,  ($\frac{1}{b}$), ($\frac{1}{c}$), ($\frac{1}{d}$)... so on

•  The equation to ascertain the consonant mean is given by:

         Harmonic Mean = n/[($\frac{1}{a}$) + ($\frac{1}{b}$)+ ($\frac{1}{c}$)+($\frac{1}{d}$)+… .]
