8. A company makes electronic components for TV's. 95% pass final inspection (and 5% fail and need to be fixed). 120 components
Taya2010 [7]

Using the binomial distribution, it is found that the variance of the number that pass inspection in one day is 5.7.

For each component, there are only two possible outcomes, either it passes inspection, or it does not. The probability of a component passing inspections is independent of any other component, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

Probability of <u>exactly x successes on n repeated trials, with p probability</u>, and has variance given by:

V(X) = np(1 - p)

In this problem:

  • 95% pass final inspection, hence p = 0.95
  • 120 components are inspected in one day, hence n = 120.

The variance is given by:

V(X) = np(1 - p) = 120(0.95)(0.05) = 5.7

The variance of the number that pass inspection in one day is 5.7.

A shipment of sugar fills 4 1/3 containers. If each container holds 2 1/7 tons of sugar, what is the amount of sugar in the enti
mr Goodwill [35]

The entire shipment contains 9 2/7 tons of sugar

Step-by-step explanation:

  • Step 1: Find the total amount of sugar in the entire shipment.

Number of containers in the shipment = 4 1/3 = 13/3

Number of tons of sugar = 2 1/7 = 15/7

⇒ Total amount of sugar = 13/3 × 15/7 = 65/7 = 9 2/7 tons
