Find the harmonic mean of $$$7$$$, $$$10$$$.


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 $$$\frac{1}{7} + \frac{1}{10} = \frac{17}{70}$$$.

Therefore, the harmonic mean is $$$H = \frac{2}{\frac{17}{70}} = \frac{140}{17}$$$.


The harmonic mean is $$$\frac{140}{17}\approx 8.235294117647059$$$A.
