no mode

The median and mode are 12

Step-by-step explanation:

The mode is the number that appears most often

Since no number repeats there is no mode

The mean is the average

Add up all the numbers

(12+12+12+12+13+13+15)/7 = 89/7 = 12 5/7

The median is the middle number

There are 7 numbers

7/2 = 3.5

The 4th number is the median

The 4th number is 12

The mode is the number that appears most often which is 12

the answer is d. (1.2, -4.7) on edgn

hope this !
