The percent of discount is 70%.
Answer:
4.6%.
Step-by-step explanation:
The probability that a can of paint contains contamination(C) is 3.23%
P(C)=3.23%
The probability of a mixing(M) error is 2.4%.
P(M)=2.4%
The probability of both is 1.03%.

We want to determine the probability that a randomly selected can has contamination or a mixing error. i.e. 
In probability theory:

The probability that a randomly selected can has contamination or a mixing error is 4.6%.
Answer:
True
Step-by-step explanation:
The size of the vertex cover is atleast twice the size of the maximum edge. Vertex must contain atleast one vertex from the matched edge. Vertex are never the strong dual solutions of each other.
128 ounces in a gallon
The pack is 33.84 ounces in total
gallon for 7=18 cents per ounce
pack for 2.39 is .07 cents per ounce
So the pack is a better deal
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
