Proof by contradiction is a form of proof that establishes the truth or the validity of a proposition, by showing that assuming the proposition to be false leads to a contradiction. I googled this so it may not be correct
Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
The correct answer is A) 37.4%.
The probability that the first volunteer is a man would be 32/52, since there are 32 men out of 52 people. The probability that the second volunteer would also be a man would be 31/51, since there is 1 fewer man and 1 fewer person total to choose from.
32/51(31/51) = 992/2652 = 0.374 = 37.4%.
6x+12x=100-2+22
18x=120
x=120/18=6.667
