Find the harmonic mean of $$$275$$$, $$$11$$$.


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 $$$\frac{1}{275} + \frac{1}{11} = \frac{26}{275}$$$.

Therefore, the harmonic mean is $$$H = \frac{2}{\frac{26}{275}} = \frac{275}{13}$$$.


The harmonic mean is $$$\frac{275}{13}\approx 21.153846153846154$$$A.
