Answer:
If it is a simple average, the average is 2.8 points.
If it is a weigthed-by-credits average, the average is 2.86 points.
Step-by-step explanation:
To calculate the simple average of this 5 grades, we sum all the points and divide it by 5:
In Algebra: A = 4 points
In History: B = 3 points
In Sociology: A = 4 points
In English: D = 1 point
In Seminar: C = 2 points
Average = (4+3+4+1+2)/5 = 2.8 points
If the average is weighted by the credits, we must add each score multiplied by the credits and, in total, divide it by the total amount of credits.
