Question

Answer to be the brainliest

Answer 1

toal observations =10 even then, n/2+n/2+1/2
10/2+10/2+1/2
5+6/2
x+2 +x+4/2 = 24
2x +6 = 24 * 2
2x +6 = 48
2x = 48 - 6
2x =42
x = 21

Answer 2

Given observations in ascending order are 8,9,12,18,(x + 2),(x + 4),30, 31,34,39.

Here, number of observations n = 10{Even}.

⇒ Median = Average of 5th and 6th observations.

⇒ 24 = (x + 2 + x + 4)/2

⇒ 24 * 2 = (x + 2 + x + 4)

⇒ 48 = 2x + 6

⇒ 48 - 6 = 2x

⇒ 42 = 2x

⇒ x = 21.

Therefore, the value of x = 21.
