ERDQuestion A group of students attend an end of semester party. The party was described by one attendee as‘very exciting’. Students played computer gamestill almost midnight! Each of the students has a name and a Player Name e.g. Fred Smith "The Slayer". Each of the games played has a name and a description. Each console has a unique serial no, name and the year of manufacture. The games can all be played on any ofthe various consolesthat have been broughtto the party. The consoles include: A Dell PC, A Playstation 3 and an X Box 360 When a player finishes a game, a judge recordsthe score obtained by the player and which console the games was played on. Assume that only the best score by a player for a console / game is recorded. a) Dothe following: o Draw theERD ▪ When converted to a relation schema, show all PKs and FKs. b) Assume that we now want to record every score recorded by a player for a console / game. o What changes are required? ▪ At 8pm Scottscore 8630 ptsfor Tetris on the PC. At 8:15 he scored 9100 pointsforthe combination.

This program is to be written in Java Language. Thank you

A College has conducted a student survey. Students were asked to rate their satisfaction with remote learning courses. Students rated their satisfaction on a scale of 1 to 5 (1 = "I hate it", 5 = "I love it"). The student responses have been recorded in a file called "StudentResponses.txt". Each line of the file contains one student response.

Program 1 You are to write a program that reads and analyzes the survey responses. Your program should read the contents of the file and place the responses into an ArrayList. Your program should write a report to a file. The file should contain the number of students who responded to the survey, along with the mean, median, and standard deviation of the responses.

Program 2 Read the file "StudentResponses.txt" and count the number of occurances of the integers from 1 to 5. Use these counters to calculate the mean, median, and standard deviation.

Your program should use functions to calculate the mean, median and standard deviation. Each function should have an ArrayList as a parameter, and should return a double. Each function including the main should have a clearly stated algorithm.

Part (b): Reversing the order of bits in a word

Recall that in our course we define a word to be a 32-bit sequence (i.e., four

consecutive bytes). For some algorithms it is useful to have a reversed version of

that 32-bit sequence. (The deeply curious can read a brief description about such

use in Fast Fourier Transform algorithm implementations by visiting Wikipedia at

this link: http://bit.ly/2rnvwz6 ).

Your task for part (b) is to complete the code in reverse.asm that has been

provided for you. Please read this file for more detail on what is required.

Some test cases are provided to you.

# Compute the reverse of the input bit sequence that must be stored
# in register $8, and the reverse must be in register $15.

Need to HAVE a web page that uses a loop to allow a teacher to enter the following information for all students in a class: student's name, mt  grade, f  grade, hW grade, attendance grade.

program should calculate each student's numeric total grade based on the following formula:course grade = (mT*0.3)+(f*0.4)+(homework*0.2)+(attendance*0.1)File Table.html looks like this:When the button is clicked, you need to prompt the user the following information:-number of students (which will determine the number of rows in your table)-student's name-mT grade-f grade-homework grade-attendance gradeOnce all the information above is provided, a JavaScript-generated table must be created.

write an algorithm and python program using the following information. also can y

How much should I study outside of class?

           

            Issue:

Your fellow students need help. This is their first year in college and they need to determine how many hours they need to study to get good grades.

Study Hours Per Week Per Class                    Grade

15                                                           A

12                                                           B

9                                                             C

6                                                             D

0                                                             F

Project Specifications:

  1. The user enters their full name and the number of credits they are taking.
  2. The user will then enter the grade they want assuming the same grade for all classes.
  3. The program displays for each student: student’s name, number of credits, total number of weekly study hours, and grade they should expect to receive. In the following format –

Name: FirstName LastName

Credits: 12

Study Hours: 60

Grade: A

  1. At the end of the program, the program displays the total number of students who used the program, the average credits taken, and the average study hours. In the following format –

Total Students: 3

Average Credits: 9

Average Study Hours: 20

You are a middle school principal in a working-class conservative community in the Midwest. One of your tenured teachers placed a series of very negative comments about you and the school on her Facebook page. These comments were made over the weekend. A number of your students informed you that they read the teacher’s comments. In fact, you heard a group of students chatting and laughing about the comments. Additionally, you receive phone calls from a number of parents who conveyed how negative and unprofessional the teacher’s comments were.

Discussion Questions

How would you react to parents and students?

How do you approach the teacher who is allegedly responsible for the negative comments?

If evidence reveals that the teacher is responsible for these comments, what action would you take?

What options are available to you in addressing this situation?

What precautions must be taken to ensure that the teacher’s rights are protected?

How do you balance the rights of the teacher against the need to protect the integrity of the school?

Please discuss the probable consequences of each option you identified.

What is your final decision? Provide a rationale for your decision.
