How do I find five different rational numbers to represent 12%? An unfair coin, with P(Heads) = 0.55 is flipped two times. It says draw a tree diagram for this and determine the probability that both flips yield the same result. I drew a tree diagram, but I don't know how to determine the...

Proof of Reflexivity suppose m is any integer now m-m=0 but 3/0 since 0=3(0) so 3/ (m-m) hence by definition n of R, mRn can anyone explain to me the logic behind following these steps to come up with this answer... per se... can anyone explain why the teacher subtracted (m-m) and...

Add the following, using the lowest common denominator: 2/3+1/6 = 1/2+1/8 = 2/3+1/4 = 1/3+5/12+1/6= 1/10+1/4+3/5= 1/6+2/3+2/9= Subtract the following: 2/3-1/3= 6/7-3/7= 11/15-7/15 Subtract the following using the lowest common denominator: 3/4-1/2= 7/9-1/3= 5/6-1/4= Multiply...
