First put them in numerical order,12, 13, 13, 15, 15, 18.since there is an even set of numbers the median is the mean of the two middle numbers12, 13, 13, 15, 15, 18.(13+15)/2=14
Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
LCM(12, 13, 18) = 468
12, 14, 15, 16, and 18 are composite numbers 11, 13, 17, and 19 are prime numbers
The average of these numbers is 12.7You calculate this by adding all the numbers up (which in this case equals 254) and then divide by the total number of numbers (which in this case is 20 numbers) 254 divided by 20 equals 12.7
The median of the numbers 10 12 13 17 17 18 27 is 17.

Make up a data set of at least 12 numbers that have the following landmarks maxium:18 range 13 mode 7 median 12
They are 13, 14, 15, 16 and 17.
One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18

To have a gcf of 18 they must have one factor of 18 in common and no other factor, ie the second factor of the numbers must be relatively prime. The multiples of 18 between 200 and 300 are: 12 x 18 = 216 13 x 18 = 234 14 x 18 = 252 15 x 18 = 270 16 x 18 = 288 12 is relatively prime to 13 13 is relatively prime to 14, 15 & 16 14 is relatively prime to 15 15 is relatively prime to 16 (Pairs of numbers are being considered, so as 12 is relatively prime to 13, 13 is also relatively prime to 12 and thus is only listed when the numbers increase, ie under 12 and not under 13.) Thus the pairs: 216 & 234 234 & 252 234 & 270 234 & 288 252 & 270 270 & 288 all have a gcf of 18.
