### Your Input

**Find the harmonic mean of $$$6$$$, $$$16$$$.**

### Solution

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 $$$\frac{1}{6} + \frac{1}{16} = \frac{11}{48}$$$.

Therefore, the harmonic mean is $$$H = \frac{2}{\frac{11}{48}} = \frac{96}{11}$$$.

### Answer

**The harmonic mean is $$$\frac{96}{11}\approx 8.727272727272727$$$A.**
