Thanks for the question, please post the remaining 2 problems and i will help you out. Below are the code for the first two projects
Let me know for any further help.
==================================================================================
# Final Project 1
# program ask user for the score of the student
# program outputs the grade
score = int(input('Enter score: '))
if score >= 90:
print('Grade A')
elif score >= 80:
print('Grade B')
elif score >= 70:
print('Grade C')
elif score >= 60:
print('Grade D')
else:
print('Grade F')
=================================================================

# Program 2
# program ask user for the number of seconds
# program prints the equivalent hrs, minutes and seconds
seconds = int(input('Enter seconds: '))
hours = seconds // 3600
seconds_left = seconds % 3600
minutes = seconds_left // 60
seconds_left = seconds_left % 60
print('{} hr(s) {} minutes and {} seconds'.format(hours, minutes, seconds_left))

Declare and initialize 4 Constants for the
course category weights:
The weight of Homework will be 15%
The weight of Tests will be 35%
The weight of the Mid term will be 20%
The weight of the Fin al will be 30%
Remember to name your Constants according to Java
standards.

Microsoft Visual Studios 2017 Write a C++ program that computes a student’s grade for an assignment as a percentage given the student’s score and total points. The final score must be rounded up to the nearest whole value using the ceil function in the <cmath> header file. You must also display the floating-point result up to 5 decimal places. The input to the program must come from a file containing a single line with the score and total separated by...

Look at this partial class definition, and then answer questions a - b below: Class Book Private String title Private String author Private String publisher Private Integer copiesSold End Class Write a constructor for this class. The constructor should accept an argument for each of the fields. Write accessor and mutator methods for each field. Look at the following pseudocode class definitions: Class Plant Public Module message() Display "I'm a plant." End Module...
In Python In this programming assignment, you will do multiple programming exercises, and eventually develop a Python application that can calculate student course grades. (6 points) Write a program called p2-1.py to: (1) create a list and add integer numbers from 1 to 100 to the list; (2) calculate the average value of all numbers in the list; and (3) print the result (screenshots). (8 points) Write a program called p2-2.py to: (1) allow a user to define how many...
(Write or type in answers, except for problem #15, which should be entered as a small program, tested, and submitted in Repl.it) 1. Write a Python statement to define a list named temps using the following elements, in order: 95, 100, 77, 54, 103, 82 2. a) What is the length of the list temps? b) What Python function can be used to obtain the length of the list? Use it in a statement to obtain the length of temps...
In this assignment, you will write a program in C++ which uses files and nested loops to create a file from the quiz grades entered by the user, then reads the grades from the file and calculates each student’s average grade and the average quiz grade for the class. Each student takes 6 quizzes (unknown number of students). Use a nested loop to write each student’s quiz grades to a file. Then read the data from the file in order...
C++ Redo PROG8, a previous program using functions and/or arrays. Complete as many levels as you can. Level 1: (20 points) Write FUNCTIONS for each of the following: a) Validate #students, #scores. b) Compute letter grade based on average. c) Display student letter grade. d) Display course average. Level 2: (15 points) Use ARRAYS for each of the following. e) Read a student's scores into array. f) Calculate the student's average based on scores in array. g) Display the student's...
