We can use the binomial theorem to find the probability that 0 out of the 15 samples will be defective, given that 20% are defective.
P(0/15) = (15C0) (0.2)^0 (1 - 0.2)^15 = (1)(1)(0.8)^15 = 0.0352
Then the probability that at least 1 is defective is equal to 1 - 0.0352 = 0.9648. This means there is a 96.48% chance that at least 1 of the 15 samples will be found defective. This is probably sufficient, though it depends on her significance level. If the usual 95% is used, then this is enough.

Answer:
7y(3x+2)
you take out the 7y from both sides
Answer:
(- 1, - )
Step-by-step explanation:
The centre is located at the midpoint of the diameter.
Using the midpoint formula , then
centre = , ) = ( , ) = (- 1, - )
Answer:
Correct choice is D. .
Step-by-step explanation:
pick any two points from the table say (0,3) and (1,2)
Now we we can use both points to find the equation of line.
slope
now plug slope m=-1 and any point say (0,3) into point slope formula
Hence correct choice is D. .
