Answer 2

Răspuns:

$\color{red} \large \bf~~~~a)~~~ \boxed{\bf Ma = 33,(3)}$

$\color{blue}\large \bf~~~ b)~~~ \boxed{\bf Ma = 44,(3)}$

$\color{green}\large\bf ~~c)~~~ \boxed{\bf Ma = 63,(3)}$

Explicație pas cu pas:

$\color{red}\Large\boxed{\bf Ma = \dfrac{a_{1}+a_{2}+a_{3}+...+a_{n}}{n} }$

$\it~~~$

$a)~~\large\bf Ma = \dfrac{23+35+42}{3}= \dfrac{100}{3}\implies \boxed{\bf Ma = 33,(3)}$

$\it~~$

$b)~~\large\bf Ma = \dfrac{45+30+58}{3}= \dfrac{133}{3}\implies \boxed{\bf Ma = 44,(3)}$

$\it~~~$

$c)~~\large\bf Ma = \dfrac{83+75+32}{3}= \dfrac{190}{3}\implies \boxed{\bf Ma = 63,(3)}$
