Step-by-step explanation:

f=80

\Sigma{fx}=2830Σfx=2830

\text{Using the formula}Using the formula

\boxed{\textbf{Mean=$\bf\displaystyle\frac{\Sigma{fx}}{\Sigma{f}}$}}

Mean=

Σf

Σfx

\text{Mean=$\displaystyle\frac{2830}{80}$}Mean=

80

2830

\text{Mean=$\displaystyle\frac{283}{8}$}Mean=

8

283

\textbf{Mean=35.375}Mean=35.375

\therefore\textbf{The mean of the given distribution is 35.375}∴The mean of the given distribution is 35.375
