Question

thr median of the observation 11 ,12 ,14 ,18,x+2, x+4 ,30, 32 , 35, 41 arranged order is 24 find the value of X.​

Answer 1

Step-by-step explanation:

n=10

hence it is a even number

we will use the formula given below :

{(n/2)th observation+(n/2+1)th observation}/2

= {(10/2 th observation)+(10/2+1th observation)}/2=24

= {5th observation +6th observation}/2=25

= {x+2+x+4}/2=24

= 2x+6=24*2

= 2x+6=48

= 2x=48-6

= 2x= 42

= X=42/2

= x=21

Answer 2

Answer:

x=21

Step-by-step explanation:

number of term are =10

sum of med-term =24

5th and 6th is med-term

(x+2+x+4)/2=24

2x+6=48

2x=42

x=21
