<span>n/2 = average number of items to search.
Or more precisely (n+1)/2
I could just assert that the answer is n/2, but instead I'll prove it. Since each item has the same probability of being searched for, I'll simulate performing n searches on a list of n items and then calculate the average length of the searches. So I'll have 1 search with a length of 1, another search looks at 2, next search is 3, and so forth and so on until I have the nth search looking at n items. The total number of items looked at for those n searches will be:
1 + 2 + 3 + 4 + ... + n
Now if you want to find the sum of numbers from 1 to n, the formula turns out to be n(n+1)/2
And of course, the average will be that sum divided by n. So we have (n(n+1)/2)/n = (n+1)/2 = n/2 + 1/2
Most people will ignore that constant figure of 1/2 and simply say that if you're doing a linear search of an unsorted list, on average, you'll have to look at half of the list.</span>
Answer: $18,000
Explanation:
Given that,
Began 2018 with a Normal balance = $5,000
Ended 2018 with a normal balance = $11,000
Unearned Revenue account was credited = $24,000
Revenue earned by professor in 2018 :
= Beginning unearned revenue + Advance payments - Ending unearned revenue
= $5,000 + $24,000 - $11,000
= $18,000
Therefore, $18,000 revenue earned by professor in 2018.
