Use Python 3, please type.

Write a Python 3 program which is an arithmetic quiz for children. The program asks the user to calculate the multiplication of two numbers generated at random in your code. The numbers should be in the range 1 through 10. User input is shown in bold black font in the example below.

You will need to use random numbers. You should type the recommended comments at the top of your code and include three test runs in the comments.

Example program run:

Please enter the result of multiplying 6 x 7 :

42

Correct.

Another question? (y/n):

y

Please enter the result of multiplying 2 x 7 :

13

Incorrect.

Another question? (y/n):

n

Write a program that counts the letters in a given string and then display the letter count in order from high to low.

The program should:

• Display a message stating its goal
• Prompt the user to enter a string input
• Count the letters in the string (hint: use dictionaries)
• Display the letter count in order from high to low (sort your letter count)
• For example, for the input Google the output should be

G - 2

O - 2

E - 1

L - 1

• Note:
  • Make sure not to count lowercase and uppercase twice (i.e., G an g should be count together)
  • Bonus: if a few letters have the same count, sort the display in an alphabetic order (like in the example)
• Make sure to include comments that explain all your steps (starts with #). Also use a comment to sign your name at the beginning of the program!

Create a simple GUI that gets the exam score and shows the corresponding letter grade by clicking on the “Convert Score to Letter Grade” button.

You must create two Java files. One is called LastNameFirstNameWeek6Prog.java, and the other is called  Museum.java.

Ensure you include ALL files required to make your program compile and run. I would like to see your .java files only.

Museum.java Class File

1.    Create a new class called Museum that describes a Museum and includes the functionality below

2.    The new class has the following five attributes:
a. officialName – the museum’s given name (i.e.:“ New Orleans Museum of Arts”,etc.), type String
b. specialty – the museum’s type (i.e.:“Art”, “Science”, etc.), type String
c. numberOfBuildings – the number of buildings in the museum, type integer
d. area – the museum’s area in square feet, type double
e. financed - type boolean - true if the museum is financed by patrons, false if not.
Use these names for attributes exactly as given here. All attributes must be private.

3.    Be sure your classes have a good set of accessor and mutator methods. Every member variable must have at least one independent accessor and one independent mutator. (see document on Program help for examples)

Ensure you use the “this” reference from within this class when referring to every instance variable or instance method of the current object.

LastNameFirstNameWeek6Prog.java Class File (Driver Program)

Write a driver program that reads information from the user about 3 museums and use this info to create 3 respective Museum objects. The following information should be read from the user per Museum:
official name
specialty
number of buildings
area in square feet
is the museum financed?

After this, using the information inside the objects the program, the driver program should evaluate and print the following output:

·        The average area of the three Museums

·        The minimum and maximum number of buildings among all the Museums

·        The name of the financed Museum with the most area.

To get the information from the objects, use accessor methods from the Museum class. Do not use local variables in main for these calculations. You may use local variables to read the information from the user, but once this information is set on the Museum objects, you must use the get methods to retrieve the information from the objects themselves.

Also do not use Arrays or any other advanced concept that was not reviewed in the class to solve this assignment. Assignments that use these concepts will only be graded 10% for presentation.

(BASH) Say I have an array of strings with about 100 numbers ranging in length from 3-6 that represent some sort of ID. Within the array of strings, there are some duplicates numbers. What I am trying to do is represent only the top 12 numbers in the form (ID, count occurence) where its ranked by the count occurrences. So the first number would not be the ID with the most digits but it would be the one with the most occurrences.  Is there a way to do this with AWK , begin? or how could i approach this problem?

Draw the NFA for language L2 = { w | w ends in 12}. Alphabet {0,1,2}

1. What is a database? Why do today’s Internet Web applications and smartphone apps need databases?
2. For the tables given as: MEMBER (MemberNumber, MemberFirstName, MemberLastName, EmailAddress)

And PAYMENT (PaymentNumber, MemberNumber, PaymentDate, PaymentAmount)

what are the primary keys of each table? Do you think that any of these primary keys could be surrogate keys? Are any of these keys composite keys? Explain how the two tables are related. Which table contains the foreign key, and what it is the foreign key?

3. Define the terms data and information.   Explain how the two terms differ.

1. MySQL can enforce referential integrity for a delete operation performed on a parent table record by ____________________ .

A. returning an error instead of deleting any rows.

B. setting the foreign key values in the related child table rows to null.

C. deleting the related rows in the corresponding child table(s).

D. applying any one of the above, (a, b or c), depending on how the foreign key constraint is defined.

2. Third normal form (3NF) eliminates which of the following issues in a table?

A. Transitive dependencies

B. Functional dependencies

C. Partial dependencies

D. Repeating, or multi-valued columns

3. For a table to be in the second normal form (2NF), each non-primary key column in the table must __________________

A. depend on only one column that is part of the composite primary key of the given table.

B. depend on all columns that make up the composite primary key of the given table.

This has to be in java and will be uploaded onto zybooks.

Write a Java program that asks the user for a date entered as 4 integers: dayNumber monthNumber date year. Where:

dayNumber

An integer from 1-7, where 1 = Sunday, 2 = Monday, ..., 7 = Saturday

monthNumber

An integer from 1-12, where 1 = January, 2 = February, ..., 12 = December

date

An integer from 1-31 representing the date.

year

An integer representing the year.

Your prompt to the user should be:

    Enter 4 integers representing dayNumber monthNumber date year:
  

You program will compute the proper dayName from the specified dayNumber and the proper monthName from the specified monthNumber. Your program will print out the specified date in the following format:

    dayNumber monthNumber date year is dayName monthName date, year
  

Please note your program will have to error check the input as follows:

Please note your program will have to error check the input as follows:

1. First the dayNumber is checked for being in the range 1..7. If that is not the case, your program should print out the following message and terminate execution:

       Invalid day number: dayNumber, please enter a number from 1..7.
         

2. Then the monthNumber is checked for being in the range 1..12. If that is not the case, your program should print out the following message and terminate execution:

       Invalid month number: monthNumber, please enter a number from 1..12.
         

3. Then the date is checked for being in the range 1..31. If that is not the case, your program should print out the following message and terminate execution:

       Invalid date number: date, please enter a number from 1..31.
         

4. Then the date must be checked for validity. For example, there is no February 30, February 31, April 31, June 31, September 31, November 31. If the date is invalid, your program should print out the following message and terminate execution:

       Invalid date: monthName, does not have date days, please enter a valid date.
         

5. Lastly, if the monthNumber = 2, and date = 29 you must verify that the year entered is a leap year, which is the only time that February 29 exists. Please see Wikipidia's Page on Leap Year. If the year is not a leap year and the user entered a date = 29, your program should print out the following message and terminate execution:

       Invalid date: year is not a leap year, February does not have date days, please enter a valid date.
         

Please note that your class should be named DateConverter.
