Find the harmonic mean of $$$22$$$, $$$30$$$.


The harmonic mean of data is given by the formula $$$H = \frac{n}{\sum_{i=1}^{n} \frac{1}{x_{i}}}$$$, where $$$n$$$ is the number of values and $$$x_i, i=\overline{1..n}$$$ are the values themselves.

Since we have $$$2$$$ points, $$$n = 2$$$.

The sum of the reciprocals of the values is $$$\frac{1}{22} + \frac{1}{30} = \frac{13}{165}$$$.

Therefore, the harmonic mean is $$$H = \frac{2}{\frac{13}{165}} = \frac{330}{13}$$$.


The harmonic mean is $$$\frac{330}{13}\approx 25.384615384615385$$$A.
