Hello there!
Median is the middle of the data set.
So, first we have to arrange it into proper numerical order (least to greatest).
2,6,10,12,15
Then, we look for the middle number.
It is 10, therefore 10 would be the median of this data set.
C
Due to the fact that it is starting from 0 and moving in a steady pattern
select the one that says "no, the estimate should be higher."
The answer is 4 because the d is already negative
X - an amount

To increase an amount by 3% you can multiply the amount by 1.03.
