9514 1404 393

Answer:

  65.6%

Step-by-step explanation:

The question is essentially asking the ratio of the volumes.

  Va = πr²h = π(15²)(20)

  Vb = πr²h = π(19²)(19)

The ratio of volumes is ...

  Va/Vb = π(15²)(20)/(π(19³)) = (15²)(20)/19³ ≈ 0.65607

Container B will be about 65.6% full when container A is empty.

vova2212 [387]
The answer is 0.4%. The probability that a unit end in a rework can be calculated using the following equation:

P(rework)= P(defects found) * P(defect)
                = .8 * .005
                = .004
                = 0.4%
