PolarNik [594]

Answer:

C.

Step-by-step explanation:

3 times 2 is 6, 2 times 5 is 10, 5 times 3 is 15. However you need 2 for each since there are 3 sets of two equal faces. So it will be 6+6+10+10+15+15

A student earned grades of Upper AA​, Upper DD​, Upper AA​, Upper CC​, and Upper BB. Those courses had the corresponding numbers
dmitriy555 [2]

Answer:

  • The grade point average is 2.92
  • The student didn't make the​ Dean's list because the​ student's GPA is less than 3.0

Step-by-step explanation:

  • I take the grades as A,D,A,C,B not AA​,DD​,AA​,CC​,BB.
  • I take numbers of credit hours as 4,2,2,3,1 not as 44​, 22​, 22​, 33​, and 11.

Since quality points to letter grades are A=​4; B=​3; C=​2; D=​1; F=0, weighted mean is the sum of the qulity points times corresponding credit hours divided by the total credit hours:

\frac{(4*4) + (1*2) + (4*2) + (2*3) + (3*1)}{12} ≈ 2.92

Since 2.92<3.0, the student is not in Dean's list.
