<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:
Organisation behaviour specialist.
Explanation:
Organisational behaviour specialists are people who study the behaviour of variety of individuals or employees in a work environment.
Organisational behaviour specialists make use of the following methods to study the behaviour of employees:
1) Anticident behaviour consequence analysis:
This involves studying the work environment of the employed, the behaviour that is generated as a result of the different conditions of the work environment and finding solutions that will lead to the elimination of such behaviours.
2) Pinpointing:
This method involves putting down certain punishments or consequences that will arise if a particular behaviour is carried out.
3) Observation and feedback:
Organisational behaviour specialist carry out different observations inorder to get a clear insight to certain behaviours, they also create feedback strategies to put an end to these negative behaviours.
Answer:
The correct option is D, eight months for the first payment; six months for the second payment
Explanation:
From the information provided,it is very clear that interest payment would not made until January 1st 2021,which is 8 months after the date of bond issue.
This means that interest due on July 1st 2020 of two months would be paid together with that which becomes due on 1st January 2021 for six months,hence the first interest payment is for 8 months while the next one would the normal six-month cycle.
As a result,it is convincing enough that option D fits the explanation in all respects.
