2.17 LAB: Word frequencies - methods Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words.
Answers
Using the knowledge in computational language in JAVA it is possible to write a code that reads a list of words.
Writting the code in JAVA:import java.util.*;
//class name LabClass
public class LabClass{
//function getFrequencyOfWord with array wordList, ListSize and currWord as parameter
public static int getFrequencyOfWord(String[] wordsList, int ListSize, String currWord){
int frequency = 0;
//for loop for iteration
for(int i=0; i<ListSize; i++){
//if current word matches with words present in list
//then increase the frequency by 1
if(wordsList[i].compareTo(currWord)==0){
frequency++;
}
}
//return frequency at last
return frequency;
}
//main function
public static void main(String[] args) {
//creating object of Scanner class
Scanner sc = new Scanner(System.in);
int size;
//asking user to input size of list
System.out.println("Enter the size of list :");
size = sc.nextInt();
//creating array of same size as user input size
String[] wordList = new String[size];
sc.nextLine();
//asking user to input array elements
System.out.println("Enter list elements one by one :");
for(int i =0; i<size; i++)
{
wordList[i] = sc.nextLine();
}
System.out.print("\n");
sc.close();
//calling function getFrequencyOfWord in every iteration by passing
//required arguments to it
for(int i=0; i<size; i++)
{
String currWord = wordList[i];
int count = getFrequencyOfWord(wordList, size, currWord);
//printing result
System.err.println(currWord + " : " + count);
}
}
}

Psychology What is one source error associated with self-report inventories, and what is one of its solutions?
Answers
Answer:
one source error associated with self-report inventories is that some people aren't very self-aware or may jump to conclusions about their systems or disorders without taking a step back and assessing all of the possibilities. a solution to this would be having the assessment taker speak to a professional, or trying to make them report their symptoms as objectively as possible.
Explanation:
Answer:
One source error is deliberate deception, and one of its solutions is having a lie scale inserted into the assessment. Another source error is social desirability, and one of its solutions is locating questions sensitive to bias and changing or dropping them. Another source error is response set, and two of its solutions are using word variations and writing questions on the assessment in different ways.

THIS IS MY EXAM FOUR QUESTIONS CAN SOMEBODY PLZZ HELP ME AN SHOW THE WORK FROM THE BOTTOM OF MY HEART PLZZ
Answers
Answer:
Answer of question 1 :
Explanation:
Let x be the legs of ducks
And y be the legs of cows
According to the question,
2x + 4y = 52...…..(i) ( as ducks ahs two legs and as cows has 4 legs)
As he has 21 animals in total so,
x + y = 21...…..(ii)
We have make the equation. We will solve them by eliminatory method or substitution method. Here, I'll go for substitution method.
From equation (ii)
x = 21 - y....…..(iii)
Putting the value of x in equation (i),
2x + 4y = 52
2( 21 - y ) + 4y = 52
42 - 2y + 4y = 52
2y = 52 - 42
y = 10/2
y = 5 ( He has 2 cows)
putting the value of y in equation (ii)
x + y = 21
x + 5 = 21
x = 21 -5
x = 16 ( He has 16 ducks)
Marisol is selling snacks at her school’s soccer games to raise money for a service project. She buys nuts in cases that contain 24 bags and granola bars in cases that contain 20 packages. She sells the nuts for $1.25 a bag and the granola bars for $1.75 a package. If she raised $160 and sold 112 items, how many cases of granola bars did Marisol buy?
Answers
Answer:
2 cases of granola bars
Explanation:
This is a classic system of equations type question.
24n + 20gb = 112 as she can only buy the items in these quantities and this is how many she bought in total
30n + 35gb = 160 as this is how much money she earns per case
I like to solve using elimination when possible. So we can multiply the first equation by 1.25
30n + 25gb = 140 then subtract this from the second equation
10 gb = 20 then divide by 10
gb = 2

Mary and Keisha run with the same constant speed but in opposite directions. The girls have: A. The same position B. Different accelerations C. Different speeds D. Different velocities
Answers
Answer:
D
Explanation:
Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.
What is velocity?According to a particular point of view and a particular unit of time, velocity is the rate at which an object changes position while travelling in one direction. Velocity is a vector quantity. It has both a magnitude and a direction. Therefore, it alters whenever either the speed or the direction do. The meter per second is the accepted unit of magnitude for velocity.
One might refer to an object as accelerating if either the magnitude or direction of the velocity vector changes. An object moving in a circle at a constant speed can be said to accelerate because the direction of the velocity changes. Although the object is moving at a constant speed, its velocity is changing. As a vector, velocity has a fixed magnitude but a fluctuating direction.
Thus, Mary and Keisha run with the same constant speed but in opposite directions. The girls have different velocities. Hence option D is correct.

Bakari is making a scale model of a large cylindrical building. The scale model has a volume that
of the building. To determine the radius and height of the scale model, Bakari divided both the ra
by 8 because the formula for the volume of a cylinder only has 2 variables.
Which statement is true?
Bakari is correct.
Bakari is incorrect. He should have divided the radius and height by 2.
Bakari is incorrect. He should have divided the radius and height by 4.
Bakari is incorrect. He should have divided the radius and height by 16.
Answers
Answer: Bakari is correct
Explanation:
Bakari is correct. If he divided both the radius and height by the same factor (in this case, 8), then the resulting scale model will have the same proportions as the original building, just scaled down by a factor of 8. The formula for the volume of a cylinder is V = πr²h, which only has two variables (the radius and height). So if Bakari wants to maintain the same proportions of the cylinder in his scale model, he needs to divide both the radius and height by the same factor. This will result in a scale model with a volume that is 1/8th the volume of the original building.
If the scale model has a volume that is 1/8 of the volume of the actual building, then the dimensions of the scale model must be 1/2 the dimensions of the actual building in order to maintain the same proportions. This means that Bakari should divide both the radius and height of the actual building by 2 in order to determine the radius and height of the scale model. Therefore, his method of dividing both the radius and height by 8 is correct.
