Given:
30% of the bulbs in a large box are defective.
If 12 bulbs are selected randomly from the box.
To find:
The probability that exactly 6 are defective.
Solution:
Probability of defective bulbs is:



Probability of non-defective bulbs is:



The probability that exactly 6 are defective is:





Therefore, the probability that exactly 6 are defective is 0.0792.

Answer:
A. (2, 5)
Step-by-step explanation:
If B and B' have symmetry, then P is a midpoint between those points. We can determinate the location of point P by using the midpoint equation, whose vectorial form is:
(Eq. 1)
If we know that
and
, then the location of P is:



Which corresponds to option A.

Answer:
d = 40/7
Step-by-step explanation:
Solve for d:
0.544444 = 28/(9 d)
0.544444 = 49/90:
49/90 = 28/(9 d)
49/90 = 28/(9 d) is equivalent to 28/(9 d) = 49/90:
28/(9 d) = 49/90
Take the reciprocal of both sides:
(9 d)/28 = 90/49
Multiply both sides by 28/9:
Answer: d = 40/7
