V = (4,-3,5)
w = (2,6,-1)
z = (3,0,4)
u = 0.5 v - w + 2 z = 0.5 (4,-3,5) - (2,6,-1) + 2 (3,0,4) 
  = ( [0.5 * 4 - 2 + 2 *3] , [0.5*-3-6+2*0] , [0.5*5--1+2*4] )
 = ( 6 , -7.5 , 11.5 )
The correct answer is option D

andreyandreev [35.5K]

Answer:

The student's GPA is 2.8666.

Step-by-step explanation:

A grade is 4.0, B grade is 3.0, C grade is 2.0. For each credit, add the value of the letter grade. So:

Math, 2 credits, grade A: (4x2=8)

English, 5 credits, grade B: (5x3=15)

Physics, 4 credits, grade B: (4x3=12)

German, 4 credits, grade C: (4x2=8)

The numbers add up to 43, then divide by the number of credits (15) to get:

43/15=GPA of 2.8666.
