2- Write a Python program that determines a student’s grade. The program will read three types of scores(quiz, midterm, final exam scores) and determine the grade based on the following rules : if the average score >=90% =>grade=A -if the average score >= 70% and <90% => grade=B -if the average score>=50% and <70% =>grade=C -if the average score<50% =>grade=F Example Input : Quiz score: 80 Mid-term score: 68 Final score: 90 Output: Your grade is B.
d) Write a Java program to input 10 integers from the user and print "True" in the output if at least 7 unique numbers are entered. Otherwise, print "False" in the output.
Please send me answer within 10 min!! I will rate you good for sure!! PLEASE ANSWER IN JAVA !!!!!! 4.16 LAB: Count characters Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. Ex: If the input is: n Monday the output is: 1 n Ex: If the input is: z Today is Monday the output is: 0 z's Ex: If the input is: n It's a sunny day the output is: 2 n's Case matters. Ex: If the input is: n Nobody the output is: 0 n's n is different than N.

1-----------Write a Java program to input marks of five subjects Physics, Chemistry, Biology, Mathematics and Computer, calculate percentage and grade according to given conditions using if-else if: If percentage >= 90% : Grade A If percentage >= 80% : Grade B If percentage >= 70% : Grade C If percentage >= 60% : Grade D If percentage >= 40% : Grade E If percentage < 40% : Grade F Example Input Input marks of five subjects: 95 95 97 98 90 Output Percentage = 95.00 Grade A
Write Java code to do the following: Read from the keyboard an unknown number of values each of which is between 1 and 100. If a number entered is not between 1 and 100 (except for -1 which ends the input) print an error message. When a -1 is read in, stop the loop and print which of the numbers between 1 and 100 were not read in

3. Write Python expressions or assignments as specified:a. Assign x to be 5, y to be 10, and z to be 8.b. Write an expression that evaluates to the average of x, y and z.c. Write an expression that evaluates to the largest value among x, y, and z.d. Write an expression that evaluates to the median value among x, y, and z (Hint:the median of a, b, and c is a+b+c - max{a,b,c} - min{a,b,c}.)
It's common to print a rotating, increasing list of single-digit numbers at the start of a program's output as a visual guide to number the columns of the output to follow. With this in mind, write nested for loops in Java to produce the following output, with each line 60 characters wide:
Suppose that x and y are int variables and the input is: 10 20.7 What is the value of x and y if the inputs are already executed: cout << x << y;
