Andre’s math teacher has 24 kids in the class. How many different ways can he arrange groups for an activity?

divide by 5

Step-by-step explanation:

list the factors of 5 to get 24 like 5x4=24

A: 82.5

Step-by-step explanation:

Average score of the 4 regular tests = (78 + 72 + 74 + 88)/4 = 78

We are told;

- the regular tests account for 40% of the final grade.

- final exam counts for 20%

- project counts for 10%

- homework counts for 30%

Thus;

weighted mean grade = (40% × 78) + (20% × 79) + (10% × 88) + (30% × 89) = 82.5
