Explanation:

In shielded twisted pair (STP) we have two wires which are twisted together and they have a shielding layer outside them which helps them to avoid interference from outside noise. STP thus having the advantage with an additional layer of shield covering the two wires together makes them more durable compared to unshielded twisted pair.

Answer: True

Explanation: Direct recursion is the process when a function call for itself and indirect recursion is the recursion process where a function calls another function and the result driven is the actual function . The aim of both the recursion process to provide with appropriate result by calling function so this declares that both the process indirect and direct recursion requite same careful analysis .

Answer:

b. Associativity

Explanation:

Associativity specifies the order in which operators are processed vis a vis operands/values in an expression. For example: Consider the expression: a + b + c. Here a + b is evaluated first before adding the result with c as the '+' operator is left associative. The default associativity can also be overridden by the use of parentheses. For example a + (b + c) . In this case b+c will be evaluated first.

Answer:

single equal sign

Explanation:

The if statement is used for check the condition.

syntax:

if(condition)

{

  statement;

}

let discuss the option one by one for find the answer:

Option a:  greater than sign

this assignment operator '>' is valid. it is used to create the condition like n>0, p>4.

Option b:  double equal sign

this assignment operator '==' is valid. it is used to check the equal condition.

like 2 == 2.

Option c:  single equal sign

this assignment operator '=' is not valid. it is used for assign the value to variable not for checking like a=2, in this 2 assign to a but it not apply the condition.

Option d:  Boolean value

we can provide the Boolean value as well if Boolean is TRUE, if condition true otherwise false.

Therefore, the option c is correct option.

1.Students at front rows will have to sit attentive and have to concentrate on the lecture being delivered,thus their knowledge about the lecture is way better than the students at back rows.

2. Front row students are more in line with the teacher and they have much better concepts regarding the lecture delivered and they have more score in exams.

3. Generally the more interested a student is about the lectures being delivered,the more front he/she is in classroom and thus this results in more grades.

Three possible cause-and-effect relationships explaining why students with good grades sit at the front include higher motivation, increased teacher attention, and the third-factor explanation such as self-confidence or socioeconomic status, which could indicate a spurious relationship.

You observe that classmates who get good grades tend to sit toward the front of the classroom, while those who receive poor grades tend to sit toward the back. Three possible cause-and-effect relationships for this nonexperimental observation could include:

It is difficult to determine without further investigation whether the observed correlation indicates a causal relationship or a spurious relationship. Investigating the root causes of this observation would require a more rigorous research design with clear independent and dependent variables, as well as controls to account for potential confounding factors.

Answer:

A. vecList.erase(position)

Explanation:

Assuming vecList is a vector container, the expression vecList.erase(position) deletes all elements from the container.

Assuming vecList is a vector container, the expression vecList.erase(position) deletes all elements from the container. Thus, the correct option for this question is A.

A vector container may be defined as a type of sequence that significantly represents arrays that can change in size. They significantly utilize contiguous storage locations for their elements. This means that their elements can also be accessed using offsets on regular pointers to their elements, and just as efficiently as in arrays.

According to the context of this question, vecList.erase(position) is the tool of the vector container in order to delete all sorts of elements that have been expressed by the vector container.

Therefore, the expression vecList.erase(position) deletes all elements from the container. Thus, the correct option for this question is A.

#SPJ5

Answer:

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

This depends on the company, but some companies will accept poor quality as long as the product works and provides them faster innovation. This will happen especially if a company knows or has an idea that a competitor is working on a similar product.

Another big reason why a company might accept poor quality in order to release a product is money. Sometimes a company does not have the budget to continue the project, therefore they release it usually in Early Access. This allows them to start making some money on the project while they continue to work on it.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

In this exercise, we are analyzing the context in which we have the quality of technological products linked to monetary value, as follows:

We know that some companies are focused on having a worse quality as long as they make a quick profit, as the consumer is not a priority.

When it comes to Price or Quality, many entrepreneurs most of the time have a false perception that the cheaper a product they tend to offer to the consumer, the greater the chances of success.

We must take into account that the option of a lower quality is often linked to the budget that a company may have.

Answer:

#include<iostream>

using namespace std;

int main(){

   //initialization

  int arr1[10] = {2,4,6,1,7,9,0,3,5,8};

  int temp;

   int size_arr;

   //nested for loop

  for(int i=0;i<size_arr-1;i++){

   for(int j=0;j<size_arr-i-1;j++){

       if(arr1[j]>arr1[j+1]){ //compare

               //swapping

           temp = arr1[j];

           arr1[j]=arr1[j+1];

           arr1[j+1]=temp;

       }

   }

  }

  //display the each element

  for(int i=0;i<10;i++){

   cout<<arr1[i]<<" ";

  }

    return 0;

}

Explanation:

Create the main function and declare the variable and defining the array with 10 values.

take the nested for loop, nested loop means loop inside another loop.

the outer loop traverse in the array from 0 to size-1.

and inside loop traverse from 0 to size -i-1, because for every cycle of the outer loop the one element is sorted at the end. so, we do not consider the element from the last for every cycle of the outer loop. That's why (size-i-1)

In the bubble sort, the first element compares with the second element and if the first id greater than the second then swap the value. so, for the above algorithm, we take the if statement and it checks the condition if the condition becomes true then the swap algorithm executes.

we take a third variable for swapping. after that, if the outer loop condition false it means all elements will traverse and then the loop will terminate.

and finally, take another for loop and display the output.

Final answer:

The answer provides a Python program example that uses the bubble sort algorithm to sort an array of 10 integers. The program defines a function, bubble_sort, which sorts the array in ascending order and then prints the sorted array.

Explanation:

To sort an array of 10 integers using the bubble sort algorithm, you can use the following program as a reference. Bubble sort compares adjacent elements and swaps them if they are in the wrong order. Here's a basic example in Python:

def bubble_sort(arr):
   n = len(arr)
   for i in range(n):
       swapped = False
       for j in range(0, n-i-1):
           if arr[j] > arr[j+1]:
               arr[j], arr[j+1] = arr[j+1], arr[j]
               swapped = True
       if not swapped:
           break
   return arr

# Example array:
numbers = [64, 34, 25, 12, 22, 11, 90, 88, 66, 23]
sorted_numbers = bubble_sort(numbers)
print("Sorted array is:", sorted_numbers)

This program will sort the given array of integers in ascending order. The function bubble_sort takes an array as input, performs the bubble sort algorithm, and returns the sorted array.

Answer:

Yes, the order in which the catch blocks are listed matter in case where multiple exceptions are caught in the same try statement and some of them are related through inheritance.

Explanation:

A try block may be followed by one or mutiple catch blocks. Each catch block should contain a separate exception handler. Thus, if we need to perform different tasks for the occurrence of different exceptions then we need to use java multiple catch blocks.

Every catch block should be ordered from the most particular to the most generic like catch for the NumberFormatException class must come before the catch for the Exception class.

Thus, the order in which the catch blocks are listed matter in case where multiple exceptions are caught in the same try statement and some of them are related through inheritance.

Answer:

read-only properties.

Explanation:

Only the read only properties can view but cannot change the data.The user don't have access to the no access properties, full-access properties can read and modify the data.The write only properties can only modify the data.So to only view the data the data should have read only properties.

% here x and y is given which we can take as

x = 2:2:10;

y = 2:2:10;

% creating a matrix of the points

point_matrix = [x;y];

%  center point of rotation  which is 2,2 here

x_center_pt = x(2);

y_center_pt = y(2);

% creating a matrix of the center point

center_matrix = repmat([x_center_pt; y_center_pt], 1, length(x));

% rotation matrix with rotation degree which is 45 degree

rot_degree = pi/4;      

Rotate_matrix = [cos(rot_degree) -sin(rot_degree); sin(rot_degree) cos(rot_degree)];

% shifting points  for the center of rotation to be at the origin

new_matrix = point_matrix - center_matrix;  

% appling rotation  

new_matrix1 = Rotate_matrix*new_matrix;          

Explanation:

We start the program by taking vector of the point given to us and create a matrix by adding a scaler to each units with repmat at te center point which is (2,2). Then we find the rotation matrix by taking the roatational degree which is 45 given to us. After that we shift the points to the origin and then apply rotation ans store it in a new matrix called new_matrix1.

Final answer:

An application to compute the radius and circumference of a circle requires creating a Main class with methods to input radius, calculate circumference, and area, formatting results to two decimal places using Math.PI.

Explanation:

To create an application that calculates the radius and circumference of a circle, you will need to define methods within your Main class. The getRadius method will prompt the user for input, calcCirc for calculating the circumference using the formula C = 2 * PI * r, and calcArea for calculating the area with A = PI * r * r. You should use the Math.PI constant for PI, and ensure all results are formatted to two decimal places.

Sample code structure in Java:

public class Main {
   public static void main(String[] args) {
       double radius = getRadius(); // prompts user and gets radius
       double circumference = calcCirc(radius);
       double area = calcArea(radius);
       System.out.printf("Radius: %.2f\n", radius);
       System.out.printf("Circumference: %.2f\n", circumference);
       System.out.printf("Area: %.2f\n", area);
   }
   // Helper methods here
}

Ensure that you correctly use double data types for storing the input from the user, as well as the calculated values, since these can include decimal points.

Answer: Early

Explanation:

The largest distribution of software cost will be in the early stages of program life cycle. The different phases in the program life cycle are edit time, compile time, link time, distribution time, installation time, load time, and run time. So during early program life cycle we have editing stage which involves correcting the code , debugging earlier codes and addition of features into the code which leads to a large software cost

Answer:

Global variables:

1. It is declare outside of all functions.

2. Cannot be declare the two global variable with same name.

3. It can be used in any where in the program, the is no problem with scope.

Local variables:

1. It is declare inside the functions.

2. Can be declare the two or more local variable with same name in the different functions.

3. It is available until that functions are executed.

Explanation:

Global variables are declare outside of all function,, we can access that variable anywhere in the program

for example:

int num = 10;

int main(){

statement;

fun(){

statement;

}

}

The variable is outside of all functions. So, it is a global variable.

It is not declare in the function or block, this is reason it has no problem with availability. it is available until the program is executed.

Other side, local variable is declare in the function.

for example:

int main(){

int num = 10;

statement;

fun(){

int num = 10;

statement;

}

}

Here, the  variable num is local variable and it can be more than one time with same name but in the different function.

it is available untill that function executed.

Explanation:

If we want to access elements at an any random offset position then we can use random access iterators.They use the functionality 'as relative to the element they point to' like pointers.Random access iterators are Bidirectional iterators that can randomly process elements,pointer types are also random-access iterators.

Answer:

We can use CREATE command to create tables with columns having descriptive names

Explanation:

Firstly, create a table using CREATE  command in SQL. The syntax is as follows:

CREATE TABLE [table_name]

(

 [col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype]),

[col_name] [datatype])

)

Once the table is created, we can insert the data into table using INSERT command. It's syntax is as follows:

INSERT INTO table_name VALUES('', '', '')

if datatype is string, values must be entered within single quotes. If datatype is int, values are entered directly without using  quotes.

Now, you can select the data from  the table using SELECT command. It's syntax is as follows:

SELECT column-list FROM table_name

If you want to filter rows according to conditions, you can use WHERE command.

I have created  sample table and inserted some data into it. Now, I applied some queries on it to select data from the table.

I have written in a text file and attached the same. Please find. Thank you!

Answer:

private int[ ] testMethod ( int x )

Explanation:

Before going to the reason first understand the syntax of declare the function.

Syntax:

Access_modifier return_type name (argument_1, argument_2,...);

Access_modifier is used for making the restriction to access the values.

it is public, private and protected.

Return_type:  it is used to define return type of the function.

it can be int, float, double.

In the question:

Option 1:  private array testMethod ( int x )

it is not valid because array is not valid return type.

Option 2: private int[ ] testMethod ( int x )

int[ ]  denotes the integer array. so, the function return the integer array.

Option 3: private double[5] testMethod ( int x )

it is not valid because double[5] is not valid return type. we cannot enter the size of the array.

if we replace double[5] to double[ ], then it valid and the function return double type array.

Option 4: private double testMethod[ ] ( int x )

it return type is double. So, it return the decimal value but not array.

Therefore, the correct option is (b).

Answer:

The first graph in the picture describes a relation that is (a) Reflexive, transitive, and anti-symmetric.

Because a, b, c, d all are related to itself, so reflexive.

where (a, b) and (b, d) are in the relation, (a,d) is in the relation,    

for (c,a) and (a,b) there is (c,b).

so it's transitive.

for all a,b in the relation, (a,b) there is no (b,a) with a ≠b.

The second graph in the picture describes a relation that is (b) Reflexive, transitive, and neither symmetric nor anti-symmetric.

Because a, b, c, d all are related to itself, so reflexive.

where (a, b) and (b, a) are in the relation, (a,a) is in the relation,                                                    

where (c, d) and (d, d) are in the relation, (c,d) is in the relation,                                                    

so it's transitive.

Because, (a,b) and (b.a) are there, but for (c,d) there is no (d,c) in relation.

So, the relation is not symmetric.

(a,b) and (b,a) is in relation but, a≠b, so not anti symmetric.

Explanation:

For all a in a set,  if (a,a) in a relation then the relation is reflexive.

For all (a,b) in relation R, if (b,a) is also in R, then R is symmetric.

For all (a,b), (b,c) in relation R, if (a,c) is also in R, then R is transitive.

For all (a,b), (b,a) in R, a = b,  then R is an anti- symmetric relation.

True.

Update expression conditions the iterations of a for loop. Counter++ is the most basic form of use, but others like total += sales are also valid.
