Some rows of the STUGRADE table of a school are shown below: ​ STU_CODE CLS_CODE GRADE YEAR 291 111 3.1 2010 938 101B 2.3 2011 931 M101 3.3 2040 291 M101 3.4 2018 190 111 2.0 2021 931 321 3.9 2003   Suppose that STU_CODE is the student code (foreign key) and CLS_CODE is the class code (foreign key). Which of the following computes the average for each year of the student with code 931?     a. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931 GROUP BY YEAR   b. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931.   c. SELECT AVG(GRADE) FROM STUGRADE GROUP BY STU_CODE = 931   d. SELECT AVG(GRADE) FROM STUGRADE WHERE STU_CODE = 931 GROUP BY AVG(GRADE)

Whoever must play, cannot play def subtract_square(queries): Two players play a game of "Subtract a square", starting with a positive integer. On their turn to play, each player must subtract some square number (1, 4, 9, 16, 25, 36, 49, ...) from the current number so that the result does not become negative. Under the normal play convention of these games, the player who moves to zero wins, leaving his opponent stuck with no possible moves. (In the misère version of the game that has otherwise identical rules but where you win by losing the original game, these definitions would be adjusted accordingly.) This and many similar combinatorial games can be modelled with recursive equations. This game is an example of an impartial game since the moves available to both players are exactly the same, as opposed to “partisan games” such as chess where each player can only move pieces of one colour. A game state is therefore determined by the remaining number alone, but not by which player has…

Create an application that finds the greatest common divisor of two positive integers entered by the user. Console Greatest Common Divisor Finder Enter first number: 12 Enter second number: 8 Greatest common divisor: 4 Continue? (y/n): y Enter first number: 77 Enter second number: 33 Greatest common divisor: 11 Continue? (y/n): y Enter first number: 441 Enter second number: 252 Greatest common divisor: 63 Continue? (y/n): n Specifications The formula for finding the greatest common divisor of two positive integers x and y must follow the Euclidean algorithm as follows: Subtract x from y repeatedly until y < x. Swap the values of x and y. Repeat steps 1 and 2 until x = 0.  y is the greatest common divisor of the two numbers. You can use one loop for step 1 of the algorithm nested within a second loop for step 3. Assume that the user will enter valid integers for both numbers. The application should continue only if the user enters 'y' or 'Y' to continue. Note that if you do…

✓ Exercises Exercise: Write a method _ and _ that computes the region representing the intersection of two regions. Exercise: Write a method _contains__, which checks whether a n-dimensional point belongs to the region. Remember, a point belongs to the region if it belongs to one of the rectangles in the region. ✓ Membership of a point in a region #@title Membership of a point in a region def region_contains (self, p): ### YOUR SOLUTION HERE Region._contains = region_contains [ ] # Tests 10 points. assert (2, 1) in Region (Rectangle((0, 2), (0, 3)), Rectangle((4, 6), (5,8))) assert (2, 1) not in Region (Rectangle((0, 1), (0, 3)), Rectangle((4, 6), (5, 8))) Exercise: Write a method _le_ for regions such that R <= S if the region R is contained in the region S. You can test this by checking that the difference between R and S is empty.

JAVA Script Create a form that has a last name, a first name, an email address, a drop-down listing of 10 cities in Massachusetts. The list is to be sorted (hint: think array), an email address, and a zip code field. Each field is to be process through a validation function. You may use one function for each but if you are creative you should be able to use just one function. The drop-down listing will not require validation because they will be choosing from a list that you are providing. This input from must be styled and show an effect to the user as to which field that are currently providing input.

Correct answer will be appreciated.else downvoted.

Java Programming Project You need to make an exam application in the project. Write the project using JavaFX. Do not use a database. Accordingly, what is requested must be performed: 1. Adding questions to the question bank: different types of questions should be added to the question bank. Question types include multiple choice, True/False, fill-in, and classic type questions. It is mandatory to use inheritance and polymorphism in writing classes related to questions and in using their objects. For example, a multiple choice question should have the following information: a) question text b) answer options such as a, b, c, d c) answer d) points e) degree of difficulty (such as easy, normal and difficult) In the upper classes, taking into account the content of other types of questions and subclasses must be determined which properties should be. 2. Removing a question from a question bank: finding a question that will be deleted first when removing a question from a question bank it…
