The project lifecycle model that is most suited for the project is called linear project management life cycle model. This is because The linear life cycle is best suited for initiatives with clear objectives from the beginning.
The definition of a linear project life cycle?The development of the initial concept through the deployment of an end result, output, or advantages are all divided into separate phases in a linear (waterfall) life cycle. High structure, predictability, and stability are the goals of this strategy.
Therefore, one can say that Fixed needs are provided for the project via linear life cycle models. The project's total cost and work volume have been defined and are not expected to vary at any point during the process. As a result, it reduces the requirement for unforeseen expenses or tasks that crop up mid-project.

This lab was designed to teach you more about using Scanner to chop up Strings. Lab Description : Take a group of numbers all on the same line and average the numbers. First, total up all of the numbers. Then, take the total and divide that by the number of numbers. Format the average to three decimal places Sample Data : 9 10 5 20 11 22 33 44 55 66 77 4B 52 29 10D 50 29 D 100 90 95 98 100 97 Files Needed :: Average.java AverageRunner.java Sample Output: 9 10 5 20 average = 11.000 11 22 33 44 55 66 77 average = 44.000 48 52 29 100 50 29 average - 51.333 0 average - 0.000 100 90 95 98 100 97 average - 96.667
Answer:
The program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String score;
System.out.print("Scores: ");
score = input.nextLine();
String[] scores_string = score.split(" ");
double total = 0;
for(int i = 0; i<scores_string.length;i++){
total+= Double.parseDouble(scores_string[i]); }
double average = total/scores_string.length;
System.out.format("Average: %.3f", average); }
}
Explanation:
This declares score as string
String score;
This prompts the user for scores
System.out.print("Scores: ");
This gets the input from the user
score = input.nextLine();
This splits the scores into an array
String[] scores_string = score.split(" ");
This initializes total to 0
double total = 0;
This iterates through the scores
for(int i = 0; i<scores_string.length;i++){
This calculates the sum by first converting each entry to double
total+= Double.parseDouble(scores_string[i]); }
The average is calculated here
double average = total/scores_string.length;
This prints the average
System.out.format("Average: %.3f", average); }
}
Write a recursive method called permut that accepts two integers n and r as parameters and returns the number of unique permutations of r items from a group of n items. For given values of n and r, this value P(n, r) can be computed as follows:
n!/(n - r)!
For example , permut (7, 4) should return 840.
Answer:
Following are the code to the given question:
public class Main//defining a class Main
{
static int permut(int n, int r)//defining a method permut that holds two variable
{
return fact(n)/fact(n-r);//use return keyword to return calcuate value
}
static int fact(int n)//defining a fact method as recursive to calculate factorials
{
return n==0?1:n*fact(n-1);//calling the method recursively
}
public static void main(String[] abs)//main function
{
//int n=7,r=4;//defining integer variable
System.out.println(permut(7,4));//use print method to call permut method and print its values
}
}
Output:
840
Explanation:
Following is the explanation for the above code.
Defining a class Main.Inside the class two methods, "permut and fact" were defined, in which the "permut" accepts two values for calculating its permutated value, and the fact is used for calculates factorial values recursively. At the last, the main method is declared, which uses the print method to call "permut" and prints its return values.Joseph learned in his physics class that centimeter is a smaller unit of length and a hundred centimeters group to form a larger unit of length called a meter.

SOMEONE PLS HELP?!?!!
Answer:
B. To continuously check the state of a condition.
Explanation:
The purpose of an infinite loop with an "if" statement is to constantly check if that condition is true or false. Once it meets the conditions of the "if" statement, the "if" statement will execute whatever code is inside of it.
Example:
//This pseudocode will print "i is even!" every time i is an even number
int i = 0;
while (1 != 0) //always evaluates to true, meaning it loops forever
i = i + 1; // i gets incrementally bigger with each loop
if ( i % 2 == 0) //if i is even....
say ("i is even!"); //print this statement
Time-management techniques work most effectively when performed in which order?
prioritize tasks, reward system, study-time survey, project schedule
project schedule, study-time survey, reward system, prioritize tasks
reward system, prioritize tasks, project schedule, study-time survey
study-time survey, project schedule, prioritize tasks, reward system
Answer:
study-time survey, project schedule, prioritize tasks, reward system.
Explanation:
Time management can be defined as a strategic process which typically involves organizing, planning and controlling the time spent on an activity, so as to effectively and efficiently enhance productivity. Thus, when time is properly managed, it avails us the opportunity to work smartly rather than tediously (hardly) and as such making it possible to achieve quite a lot within a short timeframe. Also, a good time management helps us to deal with work-related pressures and tight schedules through the process of properly allocating the right time to the right activity.
Hence, time-management techniques work most effectively when performed in the following sequential order; study-time survey, project schedule, prioritize tasks, and designing (creating) a reward system.

For this question we won't be directly working within LinkedList however. Instead, we'll be working with a Runner class:
public class Runner {
private LinkedList firstItemList;
private LinkedList listRemainder;
public Runner() {
firstItemList = null;
listRemainder = null;
}
}
For this question, write a method for the Runner class that will take in a LinkedList, split into two linked lists, and assign their values to firstItemList and listRemainder. Assign firstItemList to be a new LinkedList that just contains the first value. Assign listRemainder to be a new linkedList that contains everything EXCEPT the remainder.
More clearly, if you are given a linked list that looks like: 1 --> 2 --> 3 --> 4 Then assign firstItemList to 1 --> null and listRemainder to `2 --> 3 --> 4``
Please note this will be the only question that deals with a Runner Class instead of the LinkedList class directly.
public void split(LinkedList wholeList) {
}// end split
Solve in JAVA please using LinkedList methods and Node methods only if necessary
Answer:
Explanation:
The following method will take in a LinkedList as an argument and split it, adding only the first element to the firstItemList and the rest of the elements to listRemainder. The firstItemList and ListRemainder may have to be changed to static in order for the method to be able to access them, or add a setter/getter method for them.
public static void split(LinkedList list) {
firstItemList = new LinkedList();
listRemainder = new LinkedList();
firstItemList.add(list.peek());
list.pop();
listRemainder = list;
}
The complete java code for the Runner class can be defined as follows:
Java Code:public class Runner<T>//defining a class Runner
{
private LinkedList<T> firstItemList;//defining LinkedList type array variable that is firstItemList
private LinkedList<T> ListRemainder;//defining LinkedList type array variable that is ListRemainder
public Runner()//defining default constructor
{
firstItemList=null;//holding null value in list type variable
ListRemainder=null;//holding null value in list type variable
}
public void split(LinkedList<T> WholeLinkedList)//defining a method split that takes a list in parameter
{
if(WholeLinkedList==null)//defining if block that checks parameter variable value equal to null
return;//using return keyword
firstItemList=WholeLinkedList;//holding parameter variable value in firstItemList
ListRemainder=WholeLinkedList.next;//holding parameter variable next value in ListRemainder
firstItemList.next=null;//holding null value in firstItemList.next element
}
}
Code Explanation:
Defining a class Runner.Inside the class two LinkedList type array variable that is "firstItemList, ListRemainder" is declared.In the next step, a default constructor is defined, in which the above variable is used that holds null value in list type variable.In the next line, a method "split" is declared in which it accepts "WholeLinkedList" as a parameter.Inside this, if a conditional block is defined that checks parameter variable value equal to null if it's true it returns nothing.outside the conditional block, it checks the parameter value and holds value in it.Find out more about the linked list here:

What are the features of parameter?In general, a parameter "beside, subsidiary" is any quality that aids in describing or categorizing a certain system. In other words, a parameter is a component of a system that is crucial or useful for identifying the system or assessing its functionality, status, or other characteristics.
In some fields, such as mathematics, computer programming, engineering, statistics, logic, linguistics, and electronic music production, the term "parameter" has more precise definitions.
In addition to its technical applications, it also has broader meanings, particularly in non-scientific situations. For example, the terms "test parameters" and "game play parameters" refer to defining qualities or boundaries.
A novel method of characterizing surface texture, in particular surfaces having deterministic patterns and features, is the use of feature parameters.
Traditional methods for characterizing surface texture, such profile and areal field parameters, are considered as supplementary to the feature parameter approach.

Which of the following transfer rates is the FASTEST?
1,282 Kbps
O 1,480 Mbps
1.24 Gbps
181 Mbps
Answer:
The correct answer is 1,480 Mbps.
Explanation:
For this you have to know how to convert bytes to different units.
1,000 Bytes (b) = 1 Kilobyte (Kb)
1,000 Kilobyte (Kb) = 1 Megabyte (Mb)
1,000 Megabytes (Mb) = 1 Gigabyte (Gb)
and Finally, 1,000 Gigabytes (Gb) = 1 Terrabyte (Tb)
Answer:
1,480 Mbps
Explanation:
1,480 Mbps is equal to 1.48 Gbps, and so it is the fastest transfer rate listed because it is greater than 1.24 Gbps. In summary, 1,480 Mbps > 1.24 Gbps > 181 Mbps > 1,282 Kbps.
Create a recursive procedure named (accumulator oddsum next). The procedure will return the sum of the odd numbers entered from the keyboard. The procedure will read a sequence of numbers from the keyboard, where parameter oddsum will keep track of the sum from the odd numbers entered so far and parameter next will (read) the next number from the keyboard.
Answer:
Explanation:
The following procedure is written in Python. It takes the next argument, checks if it is an odd number and if so it adds it to oddsum. Then it asks the user for a new number from the keyboard and calls the accumulator procedure/function again using that number. If any even number is passed the function terminates and returns the value of oddsum.
def accumulator(next, oddsum = 0):
if (next % 2) != 0:
oddsum += next
newNext = int(input("Enter new number: "))
