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
