Answer:
Rate of change in elevation = 0.6 in/year
Step-by-step explanation:
Note:
Current elevation (Missing) = 7,602 feet
Given:
Old elevation = 7,602 feet
Number of year = 7,600
Find:
Rate of change in elevation
Computation:
Change in elevation = 7,602 - 7,600
Change in elevation = 2 ft
Change in elevation = 2 x 12 = 24 inches
Rate of change in elevation = 24 / 40
Rate of change in elevation = 0.6 in/year
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)](https://tex.z-dn.net/?f=V%28X%29%20%3D%20np%281%20-%20p%29)
In this problem:
- 95% pass final inspection, hence
![p = 0.95](https://tex.z-dn.net/?f=p%20%3D%200.95)
- 120 components are inspected in one day, hence
.
The variance is given by:
![V(X) = np(1 - p) = 120(0.95)(0.05) = 5.7](https://tex.z-dn.net/?f=V%28X%29%20%3D%20np%281%20-%20p%29%20%3D%20120%280.95%29%280.05%29%20%3D%205.7)
The variance of the number that pass inspection in one day is 5.7.
