In one class, homework is worth 4040% of the final grade, each of 3 projects is worth 1010%, and a final exam is worth 3030%.
(a) if a student has an 8585 homework average and a 9696 on the first project, what is the student's grade at this point?
(b) if a student gets a 7878 on the second project and a 7979 on the third project, what is the lowest grade the student can get on the final exam to get an 8080 overall in the course?

step-by-step explanation:

for the free

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
