Jordan flipped a coin 218 times. Which of the following would be a good estimate of the number of times the coin landed on heads? A. 168
B. 104
C. 209
D. 34

Ans: (1/2)218 = 109

Closest to that is 104

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
