Question

If M=26 Mean= 36 find Z??​

Answer 1

Answer:

Option ( a ) is correct.

Explanation :

By Empharical Formula:

Mode = z , median = M ,

Mean = x

z = 3M - 2x

Here ,

M = 26 , x = 36 ,

z = 3M - 2x

=> z = 3 × 26 - 2 × 36

=> z = 78 - 72

=> z = 6

Step-by-step explanation:

Answer 2

$\begin{gathered}\begin{gathered}\bf Given - \begin{cases} &\sf{mean \: = \: 36} \\ &\sf{median \: = \: 26} \end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\bf To \: Find :- \begin{cases} &\sf{mode \: } \end{cases}\end{gathered}\end{gathered}$

$\large\underline\purple{\bold{Solution :- }}$

$\tt \:  ⟼Using \: Empirical \: Formula$

$\tt \:  Mode( Z)\: = \: 3 \: Median \: \: - \: 2 \: Mean$

$\tt \:  ⟼ \: Z \: = 3 \times 26 - 2 \times 36$

$\tt \:  ⟼ \: Z \: = 78 \: - \: 72$

$\tt \:  ⟼ \: Z \: = \: 6$
