Question

Another one! (ikr how am I so rich in points?) Median of: 2, 81, 29, 18, x The average is 26.8. Solve for x!

Answer 1

x = 4, Median = 18

Explanation:

Since the Average/Mean is 26.8

So,

Mean =
`(Sum Of Observations)/(Total No.OfObservations)`

26.8 =
`(2+81+29+18+x)/(5)`

=> 26.8*5 = 130 + x

=> 134 = 130 + x

Subtracting 130 to both sides

=> x = 134-130

=> x = 4

Now, The data becomes:

=> 2,81,29,18,4

In ascending order:

=> 2,4,18,29,81

Finding Median (The middlemost no.)

=> 18

Answer 2

18

Explanation:

The average is found by adding all the numbers and dividing by 5

(2+ 81+ 29+ 18+ x)/5 = 26.8

Multiply each side by 5

(2+ 81+ 29+ 18+ x) = 134

x+130 =134

Subtract 130 from each side

x = 4

Now we want the median

List the numbers in order from smallest to largest

2,4,18,29 ,81

The median is the middle
