  • Answer:

    Jay's average score is 70.5

    Step-by-step explanation:

    The grades in a university are calculated as follows: 30% from class assignments, 35% from the final exam, and 35% from the field project.

    Jay scores 75 out of 100 in class assignments, this means the average will be = [tex]0.30\times75=22.5[/tex]

    Jay scores 65 out of 100 in the final exam, average is = [tex]0.35\times65=22.75[/tex]

    Jay scores 72 out of 100 in the field project, average is = [tex]0.35\times72=25.2[/tex]

    Total average = [tex]22.5+22.75+25.2=70.45[/tex] ≈ 70.5

    Therefore, Jay's average score is 70.5.
