Question

If mean of 4,6,8,10,x,14,16,is 10 then the value of X is

Answer 1

$\boxed{Value\:of\:x\:=\:12}$

Given ,

Total observations => 4,6,8,10,x,14,16

Number of observations => 7

Mean = 10

To find the value of X ➡

$mean \: = \: \frac{sum \: of \: observations}{no \: of \: observations}$

[ Substitute the values ]

$10 = \frac{4 + 6 + 8 + 10 + x + 14 + 16}{7}$

$10 = \frac{58 + x}{7}$

$10 \times7 = 58 + x$

$70 = 58 + x$

$70 - 58 = x$

$12 = x$

Therefore value of X = 12

Answer 2

Answer:

x is 12

Step-by-step explanation:

4+6+8+10+x+14+16÷7 ⇒10

58+x÷7⇒10

58+x⇒10×7

58+x⇒70

x⇒70¬58

x⇒12
