Answer:
D
Step-by-step explanation:
the median is the middle value of a data set in ascending order
If there is not an exact middle then it is the average of the values on either side of the middle
Arrange data in ascending order
15, 17, 19, 21, 23, 25, 26, 28, 28, 30
the middle is between 23 and 25 , hence
median = 
=

Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3
