84%, 0%, and 85%.
HINT: 1) Before you begin, review the strategy for calculating the average of a set of numbers.
a. Calculate Brandee's average. Does this average score really represent her abilities? Why or why not?
b. Brandee persuaded her teacher, Ms. Juarez, to allow her to make up the missed test. Brandee received
a 78%. Calculate her new average or mean.
c. What difference did the 0% score make? Does this new mean represent Brandee's ability more
accurately?
guys i really need help on a. b. and c. if you could that would be great
