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:
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
Answer: 1) Perpendicular
2) Concurrent
Step-by-step explanation:
The distance from a point to a line is the length of the perpendicular segment from the point to the line.
As Perpendicular segment is the shortest distance to the point of the line.
When three or more lines intersect at one point, they are concurrent.
Because Concurrent is a situation when three or more lines intersect each other at a single point.
