Question

find the value of 'x' from the data 5,2,x,2,4,8 if mean is 4​

Answer 1

Answer:

Step-by-step explanation:

$\Large{\boxed{\mathsf{Mean \Rightarrow \frac{x_1 + x_2 +...+x_n}{n} }}}$

$\Large{\mathsf{Mean \Rightarrow \frac{5+2+x+2+4+8}{6} }}$

$\Large{\mathsf{4 = \frac{21+x}{6} }}$

$\Large{\mathsf{4×6=21+x }}$

$\Large{\mathsf{24=21+x }}$

$\Large{\mathsf{24-21=x }}$

$\Large{\mathsf{3=x }}$

$\Large{\mathsf{\green{x=3} }}$
