If I read that right:
(3/5)/(-4/9) is equal to
(3/5)*(9/-4)
-27/20
-1 7/20
For the zero product property questions it's choices 2 and 3 since they're quadratics factored and set equal to zero.
for the quadratic formula questions it would be answer choices 2 and 3 also because they're unfactored trinomial quadratic expressions
Answer:

Step-by-step explanation:
Probability of getting a 7 + Probability of not getting a 7 = 1.
Odds against drawing a 7 = Probability of not getting a 7.
We could calculate the probability of getting a 7 and subtract 1 from it to get the answer.
There a four sevens in a deck of card, one of each kind.
Probability of getting a 7 =
