   public static String determineGrade(double testScore){

       String letterGrade = " ";

       if (testScore < 60){

           letterGrade = "F";

       }

}

Explanation:

Hi, I modified your code. Your methods work but you need to update the main.

Ask the user to enter five grades and store the values in different variables

Call the determineGrade method passing each grade as a parameter

Call the calcAverage method passing all the grades as parameter

Answer from: dcttechgames

1. A. All fourth graders in Michigan.

2. C. The students who were in the 60 third-grade classrooms that used each technique.

3. C. 52% of all fourth graders in Michigan cannot subtract from zero.

4. d. both a & b.

5. D. Percentage of children who passed the objective subtraction from zero.

6. C. Two new techniques for teaching subtraction from zero.

Step-by-step explanation:

1. We can make this conclusion since an assessment test often comes after students undergo the required lessons (that is using taught the new techniques, so when they entered the fourth grade the assessment would be taken to determine their performance. Hence, the population of the study is the entire fourth-graders in Michigan.

2. The sample includes only students who made up the "60 third-grade classrooms that used each technique". In other words, they were the subject of the study.

3. Remember, a parameter often refers to numbers that summarize the entire data of a particular population. So we could say, that 52% of all fourth graders in Michigan that cannot subtract from zero make up the parameter.

4. A statistic is usually any resulting values gotten from a sample. Hence, both statements a and b are statistics from the sample.

5. Remember, the dependent variable is a variable that can be influenced by another variable; the independent variable. In other words, the percentage of children who passed the objective subtraction from zero could be affected by the independent variable.

6. The independent variable is the variable that could influence the dependent variable. In other words, the two new techniques for teaching subtraction from zero could influence "the percentage of children who passed the objective subtraction from zero."

Answer from: milkshakegrande101

That is too many, but I have time to do the first question.

If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?  

Step-by-step explanation:

It is given that the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds.

The team’s best time for the race is

56.81+59.22+57.39+60.11=233.53

1 min = 60 sec

Using this conversion we get

233.53/60=3.89

Therefore the team’s best time for the race is 3.89.

If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points.

Since the team’s best time for the race is less than 4 minutes, therefore the eighth graders earn 40 points.

Explanation:

# FIXME: Create add_grade function

def add_grade(student_grades):

name, grade = input(grade_prompt).split()

student_grades[name] = grade

# FIXME: Create delete_name function

del student_grades[name]

 

# FIXME: Create print_grades function

def print_grades(student_grades):

print('Printing grades.\n')    

for name, grade in student_grades.items():

print(name, 'has a', grade)

 

student_grades = {} # Create an empty dict

grade_prompt = "Enter name and grade (Ex. 'Bob A+'):\n"

delete_prompt = "Enter name to delete:\n"

menu_prompt = ("1. Add/modify student grade\n"

"2. Delete student grade\n"

"3. Print student grades\n"

"4. Quit\n\n")

command = input(menu_prompt).lower().strip()

while command != '4': # Exit when user enters '4'

elif command == '2':

# FIXME: Only call delete_name() here

delete_name(student_grades)

elif command == '3':
