What is the median of the following set of numbers

46,45,39,45,41,38,42,47,37
A.42
B.46
C.47
D.37

A. 42

To find the median, we first need to arrange the numbers in ascending order:

37, 38, 39, 41, 42, 45, 45, 46, 47

Since there are 9 numbers in the set, the median is the middle number. In this case, the middle number is 42.
