A student's course grade is based on one midterm that counts as 5% of his final grade, one class project that counts as 25% of his final grade, a set of homework assignments that counts as 35% of his final grade, and a final exam that counts as 35% of his final grade. His midterm score is 80, his project score is 92, his homework score is 79, and his final exam score is 79. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.
His overall final score is __?
(Type an integer or a decimal rounded to one decimal place as needed.)
His letter grade is?
just multiply each partial score by its weight.
80*0.05 + 92*0.25 + 79*0.35 + 79*0.35 = ____
now figure the letter grade.
75
Ha! Well, let's do some math and see what we get!
First, let's calculate the weighted scores for each component of his grade:
Midterm score: 80 * 0.05 = 4
Project score: 92 * 0.25 = 23
Homework score: 79 * 0.35 = 27.65
Final exam score: 79 * 0.35 = 27.65
Now, let's add them all up:
Overall final score: 4 + 23 + 27.65 + 27.65 = 82.3
So his overall final score is 82.3!
Now, let's determine his letter grade based on his overall final score:
If we remember the grading scale:
A: 90 or above
B: at least 80 but less than 90
C: at least 70 but less than 80
D: at least 60 but less than 70
F: below 60
Since his overall final score is 82.3, he falls into the B category! So, he earned a B!
Hope that brings a smile to your face!
To calculate the student's overall final score, we need to calculate the weighted scores for each component and then sum them up.
Weighted Midterm Score = 80 * (5/100) = 4
Weighted Project Score = 92 * (25/100) = 23
Weighted Homework Score = 79 * (35/100) = 27.65
Weighted Final Exam Score = 79 * (35/100) = 27.65
Overall Final Score = Weighted Midterm Score + Weighted Project Score + Weighted Homework Score + Weighted Final Exam Score
Overall Final Score = 4 + 23 + 27.65 + 27.65
Overall Final Score = 82.3
The student's overall final score is 82.3.
To determine the letter grade, we need to compare the overall final score with the grading scale.
90 or above is an A. The student has not reached this range.
80 to 89.9 is a B. The student's overall final score is in this range.
70 to 79.9 is a C. The student has not reached this range.
60 to 69.9 is a D. The student has not reached this range.
Below 60 is an F. The student has not reached this range.
Therefore, the student earned a letter grade of B.
To calculate the student's overall final score, we need to multiply each component score by its corresponding weight, and then sum all the results.
Let's calculate each component's contribution to the overall final score:
Midterm score: 80 × 0.05 = 4
Project score: 92 × 0.25 = 23
Homework score: 79 × 0.35 = 27.65
Final exam score: 79 × 0.35 = 27.65
Now, we can sum up all the scores:
4 + 23 + 27.65 + 27.65 = 82.3
The student's overall final score is 82.3.
Now let's determine the letter grade based on the overall final score:
Since the grading scale is not provided, let's assume the following scale:
A: 90 and above
B: 80 to below 90
C: 70 to below 80
D: 60 to below 70
F: below 60
The student's overall final score of 82.3 falls between 80 and 90, which means he earned a B.
Therefore, the student's letter grade is B.
