It is: 35
10, 10, 20, 30, 30, 50.
30% of 40 is equal to 30 X 40 / 100 = 12 25% of 20 is equal to 25 X 20 / 100 = 5 answer together is 30X40+25X20 / 100 = 17

Median is the middle number. In case there are two middle numbers, you can either calculate the average for the result or mark both numbers.20 30 40 50 median is 35 or {30;40}
When there is an even number of items in the data set the median is the mean average of the middle two. The middle two are the two items themselves, namely 20 and 40, so the median is (20 + 40)/2 = 30.
20, 40, 50
40
25 It's the middle number from that set of 7
30% of 40 is equal to 30 X 40 / 100 = 12 25% of 20 is equal to 25 X 20 / 100 = 5 answer together is 30X40+25X20 / 100 = 17
10-20 16 20-30 4 30-40 _ 40-50 _ 50-60 _ 60-70 2
The answer can be shown by adding the two middle numbers (30 and 40), and dividing by 2. The answer is 35. :)
