A dentist asks a random sample of 75 patients whether they prefer mint, bubblegum, or cinnamon flavor toothpaste. Of these patients, 8 said that they prefer bubblegum. Based on the results of this sample, about how many of the dentist's 1,500 active patients prefer bubblegum flavor toothpaste?

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
