Find the mean proportion of \(\frac{1}{25}\) and \(\frac{1}{49}\) . |
\(\frac{1}{35}\) \(\frac{1}{49}\) \(\frac{1}{5}\) \(\frac{1}{27}\) |
\(\frac{1}{35}\) |
Mean proportion of a and b = \(\sqrt {a × b }\) ⇒ Mean proportion = \(\sqrt {\frac{1}{25} × \frac{1}{49}}\) = \(\frac{1}{5 × 7}\) = \(\frac{1}{35}\) |
