Answer:125
Step-by-step explanation:

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.
and y = 2, is just a horizontal line, check the picture below.
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.
Answer:
1/3
Step-by-step explanation:
3 in fraction form =3/1
and 3/1 x 1/3= 3/3 or 1
-2xy+3x-2xy+3x
-2xy-2xy+3x+3x ( combine like terms)
-2xy-2xy=-4xy
3x+3x=6x
-4xy+6x
Answer: B. -4xy+6x
