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!

Respuesta :

Answer:

18

Step-by-step 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

Answer:

x = 4, Median = 18

Step-by-step explanation:

Since the Average/Mean is 26.8

So,

Mean = [tex]\frac{Sum Of Observations}{Total No.OfObservations}[/tex]

26.8 = [tex]\frac{2+81+29+18+x}{5}[/tex]

=> 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
