Answer:
a = 1
Step-by-step explanation:
7*9 =
We can rewrite 9 as 10-1
7 * (10-1)
7 * 10 - 7*1
a = 1
GPA = 3.59
For calculating the GPA, first calculate the quality points for each grade and course and then add them up like shown below:
A - 4 points x 33 credit hours = 132 quality points
B - ( 3 points x 2 credit hours ) x 3 (because there are 3 courses) = 18 quality points
C - 2 points x 3 credits = 6 quality points
D - 1 point x 2 credits = 2 quality points
Now add up all the quality points = 132 + 18 + 6 + 2 = 158
Add the credit hours as well = 33 + 6 + 3 + 2 = 44
Divide the total quality points by total credit hours to get the GPA = 158/44 = 3.59
Answer:
Following are the solution to the given point:
Step-by-step explanation:
Grade of students:
Grade of student:
In point a:
Grade of
students:





Since the Grade of
student's variance is higher than
grade,
In point b:
Please find the attached file.
The plot above shows that the student of the ninth grade is spread more widely, as the student from 0-8 to 12 is from 0-4.
