A small publishing company that you work for would like to develop a database that keeps track of the contracts that authors and publishers sign before starting a book. What fields do you anticipate needing for this database

Answer:

(b) public String doMath(int value){

return " " + (value * 3);

}

Explanation:

Two of the answers doesn't even have a variable to pass into. In order, to return a String the return " " in b will do this. Therefore, I think the answer is b.

Answer:

This program is written using python

It uses less comments (See explanation section for more explanation)

Also, see attachments for proper view of the source code

Program starts here

#Prompt user for price of package 1

price1 = int(input("Enter Price 1: "))

while(price1 <= 0):

     price1 = int(input("Enter Price 1: "))

#Prompt user for weight of package 1

weight1 = int(input("Enter Weight 1: "))

while(weight1 <= 0):

     weight1 = int(input("Enter Weight 1: "))

#Calculate Unit of Package 1

unit1 = float(price1/weight1)

print("Unit cost of Package 1: "+str(unit1))

#Prompt user for price of package 2

price2 = int(input("Enter Price 2: "))

while(price2 <= 0):

     price2 = int(input("Enter Price 2: "))

#Prompt user for weight of package 2

weight2 = int(input("Enter Weight 2: "))

while(weight2 <= 0):

     weight2 = int(input("Enter Weight 2: "))

#Calculate Unit of Package 2

unit2 = float(price2/weight2)

print("Unit cost of Package 2: "+str(unit2))

#Compare units

if unit1 > unit2:

     print("Package 1 has a better price")

elif unit1 == unit2:

     print("Both Packages have the same price")

else:

     print("Package 2 has a better price")

Explanation:

price1 = int(input("Enter Price 1: ")) -> This line prompts the user for price of package 1

The following while statement is executed until user inputs a value greater than 1 for price

while(price1 <= 0):

     price1 = int(input("Enter Price 1: "))

weight1 = int(input("Enter Weight 1: ")) -> This line prompts the user for weight of package 1

The following while statement is executed until user inputs a value greater than 1 for weight

while(weight1 <= 0):

     weight1 = int(input("Enter Weight 1: "))

unit1 = float(price1/weight1) -> This line calculates the unit cost (per weight) of package 1

print("Unit cost of Package 1: "+str(unit1)) -> The unit cost of package 1 is printed using this print statement

price2 = int(input("Enter Price 2: ")) -> This line prompts the user for price of package 2

The following while statement is executed until user inputs a value greater than 1 for price

while(price2 <= 0):

     price2 = int(input("Enter Price 2: "))

weight2 = int(input("Enter Weight 2: ")) -> This line prompts the user for weight of package 2

The following while statement is executed until user inputs a value greater than 1 for weight

while(weight2 <= 0):

     weight2 = int(input("Enter Weight 2: "))

unit2 = float(price2/weight) -> This line calculates the unit cost (per weight) of package 2

print("Unit cost of Package 2: "+str(unit2)) -> The unit cost of package 2 is printed using this print statement

The following if statements compares and prints which package has a better unit cost

if unit1 > unit2:

     print("Package 1 has a better price")

elif unit1 == unit2:

     print("Both Packages have the same price")

else:

     print("Package 2 has a better price")

Explanation:

I have written the Python program based on your requirements.

Just give the path of the input file and the path for the output file correctly where you want to place the output file.

In, my code - I have given my computer's path to the input and output file.

You just change the path correctly

My code works perfectly and I have tested the code with your inputs.

It gives the exact output that you need.

I have attached the Output that I got by running the below program.

Code:

month_list={ "january":"1","february":"2", "march":"3","april":"4", "may":"5", "june":"6","july":"7", "august":"8", "september":"9","october":"10", "november":"11", "december":"12"} input_file=open('C:\\Users\\Desktop\\inputDates.txt', 'r') output_file=open('C:\\Users\\Desktop\\parsedDates.txt','w') for each in input_file: if each!="-1": lis=each.split() if len (lis) >=3: month=lis [0] day=lis[1] year=lis [2] if month.lower() in month_list: comma=day[-1] if comma==',': day=day[:len (day)-1] month_number=month_list[month.lower()] ans-month_number+"/"+day+"/"+year output_file.write (ans) output_file.write("\n") output_file.close() input_file.close()

In this exercise we have to use the knowledge in computer language to write a code in python, like this:

the code can be found in the attached image

to make it simpler we have that the code will be given by:

month_list ={"january": "1", "february": "2", "march": "3", "april": "4", "may": "5", "june": "6", "july": "7", "august": "8", "september": "9", "october": "10", "november": "11", "december":"12"}

input_file = open ('C:\\Users\\Desktop\\inputDates.txt', 'r') output_file =

open ('C:\\Users\\Desktop\\parsedDates.txt', 'w') for each

in input_file:if each

 !="-1":lis = each.split ()if len

   (lis) >= 3:month = lis[0] day = lis[1] year = lis[2] if month

    .lower ()in month_list:comma = day[-1] if comma

    == ',': day = day[:len (day) - 1] month_number =

 month_list[month.lower ()]ans - month_number + "/" + day + "/" +

 year output_file.write (ans) output_file.write ("\n") output_file.

 close ()input_file.close ()

Explanation:

To begin, i will like to break this down to its simplest form to make this as simple as possible.

Let us begin !

Here statement can be translated as: ∃x (P(x) ∧ M(x))

we require the Negation: ¬∃x (P(x) ∧ M(x))

De morgan's law can be stated as:

1) ¬(a ∧ b) = (¬a ∨ ¬b)

2) ¬(a v b) = (¬a ∧ ¬b)

Also, quantifiers are swapped.

Applying De Morgan's law, we have: ∀x (¬P(x) ∨ ¬M(x)) (∃ i swapped with ∀ and intersecion is replaced with union.)

This is the translation of above

Answer:

The java program is as follows.

import java.lang.*;

public class Numbers

{

   //variables to hold two numbers

   static int num1=-8, num2=-2;

   //method to return integer with higher magnitude

   public static int maxMagnitude(int userVal1, int userVal2)

   {

       if(Math.abs(userVal1) > Math.abs(userVal2))

           return userVal1;

       else    

           return userVal2;

   }

public static void main(String[] args) {

    int max = maxMagnitude(num1, num2);

 System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);

}

}

OUTPUT

The number with higher magnitude among -8 and -2 is -8

Explanation:

1. Two integer variables are declared to hold the two numbers. The variables are declared at class level (outside main()) and declared static.

2. The variables are initialized with any random value.

3. The method, maxMagnitude(), takes the two integer parameters and returns the number with higher magnitude. Hence, return type of the method is int.

public static int maxMagnitude(int userVal1, int userVal2)

4. This method finds the number with higher magnitude using the Math.abs() method inside if-else statement.

               if(Math.abs(userVal1) > Math.abs(userVal2))

                   return userVal1;

        else    

                   return userVal2;

5. Inside main(), the method, maxMagnitude(), is called. This method takes the two variables as input parameters.

6. The integer returned by the method, maxMagnitude() is assigned to a local integer variable, max, as shown.

      int max = maxMagnitude(num1, num2);

7. The result is displayed to the user as shown.

System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);

8. The class variables and the method, maxMagnitude(), are declared static so that they can be used and called inside main().

9. The variable, max, is called local variable since it can be used only within the main() where it is declared. It is not declared static.

10. The class is declared public since it has the main() method and execution begins with main().

11. The program is saved with the same name as the name of the public class having main(). In this case, the program is saved as Numbers.java.

12. No user input is taken for the two input parameter values. The static variables can be assigned any integer value and the program can be tested accordingly.
