Anon-profit organization provides homeless children with backpacks filled with school supplies. for the last 5 years the organization has given out 278, 310, 320, 242, and 303 backpacks filled with school supplies. what is the average number of backpacks given out in the last five years?

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
