For the data set 28, 29, 30, 30, 30, 40, the mean is 31. What is the mean absolute deviation? O A. The mean absolute deviation is 6. O B. The mean absolute deviation is 18. C. The mean absolute deviation is 3. D. The mean absolute deviation is 31.​

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
