pls mark my answer as Brainleist na pls
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
