Formula to find the surface area of a triangular prism
1 answer:
Step-by-step explanation:
In the mensuration of a triangular prism we can find the total surface area by solving for the areas of individual shape.
The triangular prism consist of
1. three rectangular surfaces
2. two triangular surfaces.
Hence the total surface area is the sum of the areas of the rectangular surface
=
and the sum of all areas of triangular surfaces
=
<u><em>In summary just find the area of each shape and add them together.</em></u>

Answer:
Step-by-step explanation:
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:
In this problem:
- 95% pass final inspection, hence
- 120 components are inspected in one day, hence
.
The variance is given by:
The variance of the number that pass inspection in one day is 5.7.
