Question

9,10,12,x,20,25; the median is 14

Answer 1

Answer:

x = 16

Step-by-step explanation:

Finding x

there are 6 numbers in the data set. hence in order to find the median we cancel out the values from the corners going in .. meaning :

9 , 10, 12, x, 20 , 25

we cancel the 9 and 25

then we cancel the 10 and 20

we are now left with 12 and x

since we know that the median is 14 we can create a formula:

$\frac{12 + x }{2}$ = 14

12 + x = 14 * 2

x = 28 - 12

x = 16

the value of x = 16

Answer 2

Hey there!

$\large\boxed{x=16}$

If you are trying to find the value of x and the median is 14, then we have to look at the middle number.

Since this set of numbers has 6 numbers, there will be 2 middle numbers. The average of the two numbers will be the median.

The middle numbers are 12 and x.

So, (12 + x) ÷ 2 = 14

Multiply each side by 2.

12 + x = 28

Subtract 12 from each side.

x = 16

The value of x is 16.

Hope this helps!
