Question

if the mean of 5,9,6, x and 3 is 8; find the value of x:​

Answer 1

Answer:

17

Step-by-step explanation:

(5+9+6+x+3)/5=8

(23+x)/5=8

23+x=8x5

23+x=40

x=40-23

x=17

Answer 2

$\huge \star \:  \bf \underbrace {ANSWER} \: \star$

‣ Given :

The mean of 5, 9, 6, x and 3 is 8.

‣ To Find :

The value of x

‣ Solution :

We know that,

❥︎ $Mean = \frac{Sum \: of \: observations} {Total \: number \: of \: observations}$

→ According to Question :

• Mean = 8

• Sum of observation = 5 + 9 + 6 + x + 3

• Total number of observations = 5

→ So, put the value here.

⇒$8 = \frac {5 + 9 + 6 + x + 3}{5}$

⇒$8 = \frac {23 + x} {5}$

⇒$8 × 5 = 23 + x$

⇒$40 = 23 + x$

⇒$x = 40 - 23$

⇒$x = 17$

$\implies \textbf {Hence, the value of x is 17.}$
