Question

Ramlal planted the following numbers of trees in six weeks: 35, 30, 45, 65, 39, 20. The mean is ​

Answer 1

• The means of this data = 39.

⠀⠀⠀⠀

Given :

Numbers of trees in six weeks :

• 35, 30, 45, 65, 39, 20.

⠀⠀⠀⠀

To Find :

• The mean of this data.

⠀⠀⠀⠀

Solution :

We know that,

$\blue{ \boxed{ \red{ \tt{Mean = \frac{Sum \: of \: the \: terms}{Total \: terms} }}}}$

• Sum of terms = 35 + 30 + 45 + 65 + 39 + 20.
• Total terms = 6.

$\implies \dfrac{35 + 30 + 45 + 65 + 39 + 20}{6} \\ \\ \implies \dfrac{65 + 110 + 59}{6} \\ \\ \implies \dfrac{124 + 110}{6} \\ \\ \implies \cancel\dfrac{234}{6} \\ \\ \implies \cancel \dfrac{117}{3} \\ \\ \implies \dfrac{39}{1} \\ \\ \implies39$

Hence,

The mean of this data is 39.

Answer 2

Answer:

✨The means of this data = 39.

$\mathfrak{ \blue{ \huge{ given : }}}$

Numbers of trees in six weeks :

35, 30, 45, 65, 39, 20.

⠀⠀⠀⠀

$\mathfrak{ \blue{ \huge{ to \: find : }}}$

The mean of this data.

⠀⠀⠀⠀

$\mathfrak{ \blue{ \huge{ solution : }}}$

We know that,

$\red{ \boxed{ \tt{ \green{Mean = \frac{Sum \: of \: the \: terms}{Total \: terms} }}}}$

Sum of terms = 35 + 30 + 45 + 65 + 39 + 20.

Total terms = 6.

$\begin{gathered}\implies \dfrac{35 + 30 + 45 + 65 + 39 + 20}{6} \\ \\ \implies \dfrac{65 + 110 + 59}{6} \\ \\ \implies \dfrac{124 + 110}{6} \\ \\ \implies \cancel\dfrac{234}{6} \\ \\ \implies \cancel \dfrac{117}{3} \\ \\ \implies \dfrac{39}{1} \\ \\ \implies39\end{gathered}$

$\mathfrak{ \purple{ \huge{ hence : }}}$

The mean of this data is 39.
