Question

If 3,8,10,x,14,18,16,20 are in ascending order and their median is 13 find the numerical value of x

Answer 1

Answer:

x=12

3,8,10,12,14,18,16,20

n=8 even

n/2,n/2+1

8/2,8/2+1

4 and 5 terms 12+14/2=26/2=13

Answer 2

The value of x is 12.

Step-by-step explanation:

Consider the provided information.

To calculate the median data should be arranged in ascending order.

Consider the data 3, 8, 10, x, 14, 18, 16, 20

Here, the number of terms are even number, so we compute the median by taking the mean of the two middlemost numbers.

Here, the middle most numbers are: x and 14

$Median=\dfrac{x+14}{2}$

It is given that median is 13.

$13=\dfrac{x+14}{2}\\\\26=x+14\\\\x=26-14\\\\x=12$

Hence, the value of x is 12.
