Answer:
And for this case we want a gpa of 3.0 taking in count that in this semester he/ she is going to take 16 credits so then the new mean would be given by:
And we can solve for and solving we got:
And from the previous result we got:
And solving we got:
And then we can find the mean with this formula:
So then we need a 3.3 on this semester in order to get a cumulate gpa of 3.0
Step-by-step explanation:
For this case we know that the currently mean is 2.8 and is given by:
Where represent the number of credits and
the grade for each subject. From this case we can find the following sum:
