Relational databaseObject-oriented databaseHierarchical databaseNetwork databaseExplanation:
The relational database has always been recognized or identified as well as using the primary key. The object database would be where the documentation has always been displayed as such an object. This same hierarchical database would be a type of database these have links to something else with either a connection. Network database does indeed have a cross-reference where this component should be pass to some other.Outline three requirements for linear programming
) For a course with n students, an n X 3 array, int[][] arr, holds scores on 3 exams. Each row holds the exam scores for one student, one exam per column. Write code to get the average of cumulative exam score, over all students. For instance, if student1 scored 50,60,65 in the three exams, and student2 scored 75,85,90, then the cumulative exam score for student1 is 175 and that for student2 is 250, and the resulting average is 212.5
Answer:
Following are the code to this question:
import java.util.*;//import package
public class Main //defining a class
{
public static void main(String[] ax)//defining main method
{
int student[][] = {{50,60,65},{75,85,90}}; //defining double array student
int Row=0,Col=0;//defining integer variable
double x;//defining double variable
for (int a = 0; a <student.length; a++)//use for loop to holding row value
{
for (int b = 0; b<student[a].length; b++)//use for loop to holding column value
{
Row += student[a][b];//add row value
Col += student[0][b];//add column value
}
}
System.out.println(x=Row/2);//dividing value and calculating average value
}
}
Output:
212.0
Explanation:
In the above code, a 2D array student is declared, that holds some value in the next step, two integer variable "Row and Col", is declared, which it uses the for loop to add value in "Row and Col", and in the next step, a double variable x is declared, that add value and calculates its average value and store its value in x variable and print its value.

Consider the following code segments, which are each intended to convert grades from a 100-point scale to a 4 point scale and print the result. A grade of 90 or above should yield a 4.0, a grade of 80 to 89 should yield a 3.0, grade of 70 to 79 should yield a 20, and any grade lower than 70 should yield a 0.0 Assume that grade is an int variable that has been properly declared and initialized Code Segmenti double points = 0.0; ir (grade > 89) points 4.0; else if (grade > 79) points + 3.0; else if (grade > 69) points += 2.0; else points + 0.0; System.out.println (points); Code Segment II double points - 0.0; if (grade > 89) points + 4.0; if (grade > 79) grade 3.0; if (grade > 69) points - 2.0; if (grade points + 0.01 System.out.println (points); Which of the following statements correctly compares the values printed by the two methods? A. The two code segments print the same value only when grade is below 80. B. The two code segments print the same value only when grade is 90 or above or grade is below 80. C. The two code segments print the same value only when grade is 90 or above. D. Both code segments print the same value for all possible values of grade E. The two code segments print different values for all possible values of grade.
Answer:
A. The two code segments print the same value only when the grade is below 80.
Explanation:
The first code segment defines a nested if-else statement with the different grade categories to compare and print and would only print one value for a given grade range. The second code segment defines several if statements for each grade range and can add multiple values to the points variable for one grade range that meets the condition.
Both code segments would only print out the same values of points for a grade range below 80.
We have constructed a Player Class for you. Add the following: public static variable: int totalPlayers Static variable should be an int. The value should be incremented whenever a new Player is constructed. public static variable: int maxPlayers Static variable should be an int. Set its value to 10. public static method: gameFull() The gameFull() static method should return a boolean of whether the total players is greater than or equal to the maxPlayers static variable.
Answer:
public class Player {
public static int totalPlayers = 0;
public static int maxPlayers = 10;
public static boolean gameFull() {
return totalPlayers >= maxPlayers;
}
public Player() { // Player class constructor
totalPlayers++;
}
}
Explanation:
The Java program defines the class Player which has two public class variables and a public method. The class constructor increases the totalPlayer variable by one for every player object created.
Your organization has hired a penetration tester to validate the security of your environment. The penetration tester needs to document which ports are being listened on for the various servers. Which type of tool will the penetration tester most likely use
Answer:
Port scanner
Explanation:
The penetration tester would most likely use a port scanner. A port scanner can be explained to be an application that is made to check a server or host for ports that are open. This application can also be used by administrators to check their security networks so as to know those network services that are running on a host and also to know existing vulnerabilities. Attackers also use this to exploit victims.
Write a function that will find the cost to send an international fax. The service charge is $7.00. It costs $0.45 per page for the first ten pages and $0.10 for each additional page. Take as parameter the number of pages to be faxed, and calculate the total amount due. The total amount due is returned to the main program.
Answer:
This function is written in python
def intlfax(pages):
if pages <=10:
fax = 7 + 0.45 * pages
else:
fax = 7 + 0.45 * 10 + 0.10 * (pages - 10)
return fax
Explanation:
This line defines the function
def intlfax(pages):
This checks if pages is less than or equal to 10 and calculates the fax
if pages <=10:
fax = 7 + 0.45 * pages
If otherwise, it also calculates the fax (differently)
else:
fax = 7 + 0.45 * 10 + 0.10 * (pages - 10)
This returns the calculated fax
return fax
Climatologist use weather balloons, stethoscopes, and satellites true or false
Answer:
False.
Explanation:
A stethoscope is a medical instrument which is used for listening to the work of the heart and lungs. It consists of a microphone that rests on the patient's chest, and rubber tubes that bring the sound to the earphones. An ordinary stethoscope does not have any moving or electrical parts, as it only mechanically conducts sound from the patient's chest to the doctor's ear. One of the simplest examinations that doctors perform today is listening to the lungs and heart with a stethoscope. With the help of this instrument, noises are heard during the work of the lungs and heart.

Topic: Pseudo-codes
Example 5
A shop sells books, maps and magazines. Each item is identified by a unique 4 –
digit code. All books have a code starting with a 1, all maps have a code starting
with a 2 and all magazines have a code beginning with a 3. The code 9999 is used
to end the program.
Write an algorithm using pseudocode which input the codes for all items in stock
and outputs the number of books, maps and magazine in stock. Include any
validation checks necessary.
(NOTE: A 4-digit code implies all books have a code lying between 1000 and
1999, all maps have a code lying between 2000 and 2999 and all magazines a code
lying between 3000 and 3999. Anything outside this range is an error)
Answer:
//program_start
//variable_inicialization
books = 0
maps = 0
magazines = 0
//End variable_inicialization
//operation_selection_routine
display "Select operation: (I) for input item to stock, (O) for output items in stock
operation = read_keyboard_input
IF (operation = "I")
goto input_routine
ELSE IF (operation = "O")
goto output_routine
ELSE
display "Incorrect option, try again"
goto operation_selection_routine
ENDIF
//End operation_selection_routine
//input_routine
display "Insert item code to add to stock"
input_code = read_keyboard_input
IF (input_code >= 1000 & input_code < 2000)
IF (input_code NOT duplicated_in_stock)
add_to_stock (input_code)
books = books + 1
display "Book added"
ELSE
display "Item Code is already present in stock"
ENDIF
ELSE IF (input_code >= 2000 & input_code < 3000)
IF (input_code NOT duplicated_in_stock)
add_to_stock (input_code)
maps = maps + 1
display "Map added"
ELSE
display "Item Code is already present in stock"
ENDIF
ELSE IF (input_code >= 3000 & input_code < 4000)
IF (input_code NOT duplicated_in_stock)
add_to_stock (input_code)
magazines = magazines + 1
display "Magazine added"
ELSE
display "Item Code is already present in stock"
ENDIF
ELSE IF (input_code = 9999)
goto program_end
ELSE
display "Incorrect option, try again"
goto input_routine
ENDIF
goto operation_selection_routine
//End input_routine
//output_routine
display "Items in stock"
display "Number of books: " + books
display "Number of maps: " + maps
display "Number of magazines: " + magazines
goto operation_selection_routine
//End output_routine
//program_end
display "Terminating stock program"
stop_program
Explanation:
Pseudo code is a way to design an algorithm using normal words and terms, that are not specific to any programming language. It is easier to understand how the program works and once finished, can be translated to the desired programming language.
This algorithm uses 5 blocks of code:
*variable_inicialization, where item counters are initially set to zero.
*operation_selection_routine, where the program request user input to select if the user will add an item or show existing items in stock. If an incorrect option is given, it will repeat this same routine.
*input_routine, the program will request the four digit code to add, and will check if it is not already present (to avoid duplicated items), and if the item code belongs to a book, map or magazine, increasing the corresponding item counter. Also, if the code is 9999 it will go to the program_end routine, otherwise it will display an error message and request a new item code. After a valid item code it will return to the operation_selection_routine.
*output_routine, it will display on screen the number of items for each category. Then, returns to the operation_selection_routine.
*program_end, it will simply display a goodbye message and terminate the program.

Reports offer an approach to view, design, and sum up the data in your Microsoft Access information base. For instance, you can make a basic report of telephone numbers for every one of your contacts, or a rundown report on the absolute deals across various locales and You can make a wide range of reports in Access, going from the easy to the complex. Start by contemplating your report's record source.
Regardless of whether your report is a straightforward posting of records or a gathered rundown of deals by area, you should initially figure out which fields contain the information you need to find in your report, and in which tables or inquiries they reside.
Which sentence is an effective example of language for the following scenario?
Aaron's coworker Bryce has not been working on the team project their boss assigned them.
Answer:
"I feel like this assignment isn't a priority to you"
Explanation:
Given that I-language is a term used in the depicting or forming individuals' perception or point of view of a given situation or statement instead of the actual statement. It is fully known as Internal language.
Hence, in this case, the term "Aaron's coworker Bryce has not been working on the team project their boss assigned them, " can be translated into "I feel like this assignment isn't a priority to you" in I-Language.
