What are the similarities and differences between these data sets in terms of their centers and their variability?
data set a: 6, 7, 8, 8, 8
hurry 15 points
data set b: 5, 7, 7, 2, 1
select from the drop-down menus to correctly complete the statements.
comparing the centers of the data sets, the mean for data set a is the mean for data set b.
further, based on the range, data set is more variable.

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
