Answer:
312
Explanation:
To find the median of a set of numbers, we need to arrange them in order from smallest to largest and then find the middle number. If there are an odd number of values, the median is the middle number. If there are an even number of values, the median is the average of the two middle numbers.
Arranging the given numbers in order from smallest to largest, we get:
21, 45, 121, 300, 312, 333, 347, 421, 614
There are nine numbers in the set, which is an odd number, so the median is the middle number. The middle number is the fifth number in the ordered list, which is:
Median = 312
Therefore, the median of the given set of numbers is 312.
