Please help! Lisa is conducting an experiment which involves rolling a pair of number cubes numbered 2 from 1 through 6. Rolling the sum of 12 is predicted to occur only 1 out of every 36 times. If Lisa has already rolled three 12s out of 10 rolls, how might she get her results closer to the predicted results?

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

tube or goog would be a great resource to with that question

you probably already have the answer but anyways it's b. 15.0
