Step-by-step explanation:

6+8+9+x+13=10*5

36+x=50

x=50-36

x=14

Answer 2

Given :-

• The mean of 6,8,9,x,13 is 10..

To find :-

• The value of x

Solution :-

we know that,

$\blue{\bigstar}\:{\underline{\boxed{\bf\red{Mean=\dfrac{Sum\:of\:observation}{Number\:of\:observation}}}}}$

$\rm\longrightarrow\:10=\dfrac{6+8+9+x+13}{5}$

$\rm\longrightarrow\:10=\dfrac{36+x}{5}$

$\rm\longrightarrow\:10\times\:5=36+x$

$\rm\longrightarrow\:50=36+x$

$\rm\longrightarrow\:50-36=x$

$\rm\longrightarrow\:14=x$

$\rm\longrightarrow\:x=14$

Hence,the value of x will be 14.

➝ Mean :- Mean of a number of observations is the sum of the value of all the observations divided by the total number of observations.
