Based on an averaging grading system, what will be the final grades of student A when the final grades in the four grading periods are as follows:

1st grading -80
2nd grading - 78
3rd grading - 82
4th grading - 80

a) 80
b) 81
c) 82
d) 79



Answer :

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.
