What the mean of 65, 50, 44, 86, 90, 50, 35, 110, 70, 50, 35, 60, 56?

$\large\text{Hey there!}$

$\text{Your \boxed{mean} is known as your \boxed{\bf{average}}}$

$\text{The mean/average formula is: \boxed{\rm{\dfrac{sum\ of\ all\ numbers\ in\ the\ data\ plot}{total\ number(s)\ in\ the\ data\ plot} = mean}}}$

$\rm{Equation \rightarrow \dfrac{65 + 50 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{\dfrac{65 + 50 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{ = \dfrac{115 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{= \dfrac{159 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{= \dfrac{245 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{335+ 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{385 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{420 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{530+ 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{600 + 50 + 35 + 60 + 56}{13}$
$\rm{= \dfrac{650 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{685 + 60 + 56}{13}$

$\rm{= \dfrac{745 + 56}{13}$

$\rm{= \dfrac{801}{13}}$

$\rm{= 61.6154}$

$\rm{\approx 62}$

$\huge\text{Therefore, your answer should be:}$

$\huge\boxed{\underline{\underline{\frak{61.6154}}}}\ \huge\boxed{\approx \frak{62}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
