Answer:
Step-by-step explanation:
For each component, there are only two possible outcomes. Either it fails, or it does not. The components are independent. We want to know how many outcomes until r failures. The expected value is given by
In which r is the number of failures we want and p is the probability of a failure.
In this problem, we have that:
r = 1 because we want the first failed unit.
The expected number of systems inspected until the first failed unit is 2.5
Answer:
the length of the bridge in miles is 3.37 miles
Step-by-step explanation:
The computation of the length of the bridge in miles is shown below:
Given that
The length is 5927.261 yard
As we know that
1760 yard = 1 mile
So 1 yard = 1 ÷ 1760 mile
For 5927.261 yard, the miles would be
= 5927.261 ÷ 1760
= 3.37 miles
Hence, the length of the bridge in miles is 3.37 miles
