Answer:
The mean would be 49, the median would be 48
Explanation:
To get the mean, add all of the numbers together and divide by the total number of numbers.
31 + 49 + 99 + 30 + 35 + 48 + 51 = 343
343/7 = 49
Now, to get the median, put in sequential order and find the middle number.
30, 31, 35, 48, 49, 51, 99
