The five numbers are divided by that 5 when added
7 + 8 + 12 + 15 + 18 = 60
60/5 = 12
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
First put them in ascending order. 1, 5, 7, 9, 9, 12, 14, 15, 18 Mean is 10 Median is 9 Mode is 9 Range is 17
mode
18/21 x 15 is 12 6/7
6.

One possibility: 5, 6, 7, 7, 7, 12, 12, 13, 14, 15, 16, 18
First put them in ascending order. 1, 5, 7, 9, 9, 12, 14, 15, 18 Mean is 10 Median is 9 Mode is 9 Range is 17
mode
5/12:7/18= (5/12)/(7/18)= (5/12)*(18/7)= 15/14
7 occurs more than any other number, so it is the mode.
well, the mode is basically asking you what number appears the most frequently. 6, 6, 7, 8, 9, 9, 9, 12, 12, 12, 15 in the sequence, the mode would either be 9 or 12 because those are the numbers that appear the most frequently.
18/21 x 15 is 12 6/7
Make up a data set of at least 12 numbers that have the following landmarks maxium:18 range 13 mode 7 median 12
6.
Mean = 7.9 Median = 7 and 8 Mode = 4 and 12 Range = 2 to 15.
The mode is 15 because it occurs most often
