Question

 If the median of the data 8 , 11 , 2x +3, 2 x + 9, 23 , 29 written in ascending order, is 18 then x equals to​

Answer 1

Step-by-step explanation:

if there are even number of term median is the average of the middle most two terms

the median of the data 8 , 11 , 2x +3, 2 x + 9, 23 , 29 written in ascending order, is 18

so

$median = \frac{2x + 3 + 2x + 9}{2} = 18$

$= > \frac{4x + 12}{2} = 18$

$= > 4x + 12 = 18 \times 2$

$= > 4x = 36 - 12 = 24$

$= > x = \frac{24}{4}$

$there \: fore \: x = 6$
