d.(x - 9) (x - 3)
Step-by-step explanation:
x² - 12x + 27 = 0
x² - 9x - 3x + 27 = 0
x(x - 9) - 3(x - 9) = 0
(x - 9) (x - 3) = 0
Answer:
4
Step-by-step explanation:
There are 2 outcomes for the first flip and 2 outcomes for the second flip
Multiply
2*2 = 4
P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4



The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.
Step-by-step explanation:
150=45
150 -25=x
:150=45
125=x
cross multiply
150x/150=5625/150
x=38 days
Answer:
