The data set below has 7 values. Find the mean absolute deviation for the data set.
If necessary, round your answer to the nearest hundredth.

12,22,23,16,18,19,15

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

i think that you should ask google for the answer to that problem because if we don't know it google does

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
