What is the mean and median???

average amount=mean.  middle number=median

Step-by-step explanation:

The mean is a type of average. It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. ... Then divide the sum by how many values there are. So if you have five values, add them all together, then divide the result by five. That is the mean.

The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above

median: 25  |  mean: 24.9

Step-by-step explanation:

(21+22+22+24+25+25+25+25+26+26+26+27+27+28)/14 = 349/14=24.9

21  22  22  24  25  25 25  25  26  26  26  27  27  28

25 are the middle numbers when they are put in order, and therefore 25 is the median. (average of 25 and 25 is 25.)

x> 6

8x+8> 7x+14

8x-7x> 14-8
