Answer:
The final grade of student A is:
a) 80
Step-by-step explanation:
To determine the final grade of student A based on an averaging grading system, we calculate the mean of the grades from the four grading periods.
Here are the grades for each grading period:
- 1st grading: 80
- 2nd grading: 78
- 3rd grading: 82
- 4th grading: 80
The formula for the average grade is:
[tex]\[ \text{Average Grade} = \frac{\text{Sum of all grades}}{\text{Number of grades}} \][/tex]
First, we sum the grades:
[tex]\[ 80 + 78 + 82 + 80 = 320 \][/tex]
Next, we divide the sum by the number of grades (which is 4):
[tex]\[ \text{Average Grade} = \frac{320}{4} = 80 \][/tex]
So, the final grade of student A is:
a) 80
The final grade is a) 80 for student A.
To calculate the final grade based on an averaging grading system, we follow these steps:
- Add all the grades together: 80 + 78 + 82 + 80 = 320.
- Divide the total by the number of grading periods: 320 / 4 = 80.
- According to standard rounding rules, the final grade of 80 is accurate and does not require rounding.
Therefore, the final grade for student A is 80.
