Grade-Point Average Marissa has just completed her second semester in college. She earned a B in her five-hour calculus course, an A in her three-hour social work course, an A in her four-hour biology course, and a C in her three-hour American literature course. Assuming that an A equals 4 points, a B equals 3 points, and a C equals 2 points, determine Marissa’s grade- point average for the semester.

Approximately Marissa’s grade- point average for the semester is 3 that is grade B.

Step-by-step explanation:

We are given the following in the question:

Grade in five-hour calculus course = B

Grade in her three-hour social work course = A

Grade in her four-hour biology course = A

Grade in her three-hour American literature course = C

A = 4 points

B = 3 points

C = 2 points

We will calculate weighted mean.

Thus, approximately Marissa’s grade- point average for the semester is 3 that is grade B.

k

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
