Answer 1

$\large\boxed{\begin{array}{l}\huge\boxed{\boxed{\boxed{\boxed{\sf\overline{\sf x}=\sum\dfrac{x_i\cdot f_i}{n}}}}}\\\sf\overline{\sf x}\longrightarrow M\acute{e}dia\, aritm\acute{e}tica\\\sf x_i\longrightarrow Valor\\\sf f_i\longrightarrow Frequ\hat{e}ncia\, absoluta\,(f_i)\\\sf n\longrightarrow Total\end{array}}$$\large\boxed{\begin{array}{l} \sf\overline{\sf x}=\sum\dfrac{x_i\cdot f_i}{n}=\dfrac{15}{5}\\\Huge\boxed{\boxed{\boxed{\boxed{\sf\overline{\sf x}=3}}}}\end{array}}$
