The diameter is the cross section of the widest part of a sphere.
7 + x/4 = 5 (common denominator is 4)
4(7+x/4) = 4 x 5 (distribute the 4 though parenthesis)
4 *7 +4x/4 = 4 x 5
4 * 7 + x = 4 x 5
28 + x = 4 x 5
28 + x = 20 (subtract the 28)
x = 20 - 28
x = -8
Answer: Probability that the entire batch will be accepted is 0.658.
Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.
Step-by-step explanation:
Since we have given that
Number of CDs = 507
Number of defective = 65
Since the entire batch will be accepted.
So, the probability of success is p = 
and the probability of failure is q = 
Number of CDs selected = 3
So, Probability that the entire batch will be accepted is given by

Hence, Probability that the entire batch will be accepted is 0.658.
Yes, this suggests entire batch of good CDs as it is the only condition to get accepted.
