If an element is present in an array of length n, how many element visits, on average, are necessary to find it using a linear search

Answers

Answer 1

Answer:

n/2

Explanation:

A linear search starts at the beggining of the array at index 0 and searches for the specific element by analyzing one element at a time. Meaning that if it does not exist in index 0 it moves to index 1 and if its not there it moves to index 2 and so on. If the element is not present in the array it finishes the array and ends, otherwise if it finds the element the search automatically ends. This means that on average the search would end early half of the time. This would mean that on average a total of n/2 elements are visited using a linear search.

The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the average of those numbers, and displays the numbers and their average to the user.

The program uses methods to:

1) get the numbers entered by the user all on one line separated by spaces;

2) calculate the average of the numbers entered by the user; and

3) print the results.

The first method should take no arguments and return a String of numbers separated by spaces.

The second method should take a String as its only argument and return a double (the average).

The third method should take a String and a double as arguments but have no return value.

IF user input is: 20 40 60 80 100

if ur computer is runing slowly what is most likey to slove the problem

One way to solve this problem is if you clear up some storage space. On my computer things were running very slowly and I checked my storage and it was beyond full. Another way would be to clean up your hard drive, run some virus and malware scans as your computer may have some viruses that would be slowing it down. Some others ideas are to download more memory on your computer, install a faster hard drive, and reinstall or upgrade your operating system. I hope this helps!!

O Tristen created handouts, Wyatt saved as a video, and Reed saved as a PDF.
O Tristen created a video, Wyatt broadcasted, and Reed saved as a video

Answers

Since Tristen want her students to take notes on her presentations, she should have some sort of handout.

Because Wyatt, wants to ensure that students who do not have PowerPoint can still view his presentations, converting it into a pdf is best.

Since Reed's students are very visual, converting his slides into a video will make it better for students who want to spend some time assessing some of the graphs or equations.

Thus, A is the best choice.

Which of the following characterizes pooled interdependence? Multiple Choice Each member has a great deal of discretion in terms of what they do and with whom they interact while collaborating to accomplish the team’s work. Interaction in the team only occurs between members who perform tasks that are next to each other in a sequence. Members interact with a subset of other members to complete the team’s work. Group members complete their work assignments independently, and then this work is simply "piled up" to represent the group’s output. Different tasks are done in a prescribed order, and the group is structured such that the members specialize in these tasks.

Answers

Answer:

Group members complete their work assignments independently, and then this work is simply "piled up" to represent the group’s output.
