Answer: 19
Step-by-step explanation:
The first thing you have to do is order the numbers from least to greatest: 3, 9, 29, 50.
Next you have to find out which number is in the middle, but since there are an even set of numbers there will be 2 numbers in the middle. The 2 numbers in the middle would be 9 and 29.
The next step is to find the mean, or average of 9 and 29. To find the mean of something you have add all the numbers together and divide the sum by the amount of number there are. So we would have to add 9+29 which is 38, then we have to divide 38 by 2 since there are 2 numbers. 38 divided by 2 is 19.
So that means the median is 19.
