Answer:

B. The cost of tour t is at most twice the cost of the optimal tour.

Explanation:

You are using a polynomial time 2-approximation algorithm to find a tour t for the traveling salesman problem.

The cost of tour t is at most twice the cost of the optimal tour

The equation represented as Cost(t) <= 2 Cost(T)

Where

Cost (t) represents cost of tour t

Cost(T) represents cost of the optimal tour

Which are factors that go into a project plan? Choose four answers.
USPshnik [31]

Factors that go into a project plan

  • Estimate the scope of work, based on similar projects.
  • Make sure everyone takes responsibility.
  • Creating and defining team goal
  • Working to a budget

Explanation:

Project Estimating  : Every project is different, but that doesn’t mean you have to start from zero each time. The best way to make sure you’re on the right track is to approach it from every angle. Consider similar projects, talk to your team, and understand what the client is expecting and how they’d like things to go.

Managing your team size  : A smaller team is usually preferable as it puts your project in the most ideal position to be completed on time and at the quality you expect, without burning out your team members. A smaller team also reduces the number of communication channels, which means there’s less opportunity for misinterpretation or people simply missing something.  

Planning and managing your team resources  : That said, there may be a time when you don’t have the right resources in-house to do the job. Either they are fully allocated to another project or no one has the right skill set. In this situation you have two options, either bring in freelance contractors or hire a new employee to fill the role.  

Creating and defining team goals  : The planning phase is when you’ll want to work with the team to understand what their individual goals are for the project. Is there something different they’d like to try? A test or new idea they’d like the chance to prove? Or perhaps a roadblock they want to avoid?

Scheduling Tasks to a Project Timeline  : The timeline of the project will largely be determined by the client, as they often have deadlines they need to hit to meet certain business goals that are simply out of your control. However, setting clear expectations and agreeing on the timing of key deliverables is crucial.

You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although
Vikki [24]

Answer:

Troubleshooting steps to take:

  1. Restart the tablet
  2. Restart the projector

Explanation:

When such problems occur, the basic and quick troubleshooting step is to restart the device or devices involved.

  1. Restart the tablet: This could come in handy regarding this problem. The inability to connect to the projector could be due to the inability of a specific service or driver needed for the projector. Restarting the tablet will load up the drivers and services again to enable smooth connections. When a restart is done, bugs are fixed, internet connection is rectified, memory leaks are stopped, performance is aided, the RAM (Random Access Memory) is flushed or cleaned. This should resolve the problem, however, if not, try number 2.
  2. Restart the projector: There are driver software on projectors, and due to one system failure or another, these software may fail to load. This could affect its connection to another device. As done in (1), restarting the projector will fix those bugs and load up, which should solve the connection issue.

Consider the following method, which is intended to return an array of integers that contains the elements of the parameter arr
Gennadij [26K]

Code:

public static int[] reverse(int [] arr){

Int [] newArr = new int[arr.length];

for (int k = 0; k<arr.length;k++){

/*Missing statement */

}

return newArr;

Answer:

Replace the comment with:

newArr[k] = arr[arr.length-k];

Explanation:

Required

Complete the code

In the given code:

The first line of the given code defines the method

public static int[] reverse(int [] arr){

The next line declares array newArr withe same length as array arr

Int [] newArr = new int[arr.length];

The next line iterates through the elements of array arr

for (int k = 0; k<arr.length;k++){

The /* Missing statement */ is then replaced with:

newArr[k] = arr[arr.length-k];

The above statement gets the elements of array arr in reversed order.

This is so because, as the iteration iterates through array arr in ascending order, arr.length-k gets the element in reversed order
