To work out the median, you need to numerically sort the data (because currently, it's unordered).
The ordered set of data is: 22, 38, 44, 59, 70, 79, 85, 87, 96
Now you just need to pick the middle value, which is 70:
(as you can see: 22, 38, 44, 59, 70, 79, 85, 87, 96)
Therefore, your answer is 70 :)
Hello,
59, 22, 87, 44, 96, 38, 70, 85, 79
=> 22 ; 38 ; 44 ; 59 ; 70 ; 79 ; 85 ; 87 ; 96
The median is 70.
Bye :)
Answer:
c
Step-by-step explanation: if you remove the 0 then you get 3.27
x=6
XY=24 units
YZ=18 units
Step-by-step explanation:
we have that
Y is between X and Z
substitute the given values and solve for x
therefore
18 1/2 or 37/2
To calculate the average of something, we add the numbers and divide by the count of those numbers. In this case, we have this as the sum of the numbers:
9 × 20 + 4 × 19 + 3 × 18 + 5 × 17 + 12
And the number of students as the count:
9 + 4 + 3 + 5 + 1
Now to calculate that out:
(9 × 20 + 4 × 19 + 3 × 18 + 5 × 17 + 12)/(9 + 4 + 3 + 5 + 1) ⇒
(180+76+54+85+12)/(9+4+3+5+1) ⇒
407/22 ⇒
37/2⇒
18 1/2
Answer: 5-3x = 17
