To find the average of the numbers 12, 18, 7, and 23, first add them together: 12 + 18 + 7 + 23 = 60. Then, divide the total by the number of values, which is 4: 60 ÷ 4 = 15. Therefore, the average is 15.
(-18-23+20)/3= (-21)/3=-7
Mean = Average of all numbers5 + 14 + 7 + 4 + 12 + 6 + 14 + 6 + 18 + 12 = 9898/10 = 9.8Mean = 9.8
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
The median is 20. When a list has an even number of data, there is no one middle value, so instead you average the two middle values (in this case 18 and 22) to get the median.
18/7 * 9/12 = 18/7 * 3/4 = (18*3)/(7/4) = 54/28 = 27/14

median = 11.5 mean = 12
5/12:7/18= (5/12)/(7/18)= (5/12)*(18/7)= 15/14
