Question

a student has the following averages.
homework: 94.6%
midterm: 65%
quizzes: 87.1%
final exam: 62%
find the students grade assuming these weights: homework (5%), quizzes (5%), midterm (35%), final exam (55%). what effect does the heavily - weighted final exam have in this case?

complete the table below.
(type integers or decimals rounded to two decimal places as needed.)

category	grade	weight	grade * weight
quizzes	87.1	0.05	4.36
midterm	65	0.35	22.75
final exam	62	0.55	34.1
	sum =		sum =

Explanation:

Step1: Calculate the sum of weights

The weights are 0.05 + 0.05+0.35 + 0.55=1

Step2: Calculate the sum of grade - weight products

The sum of grade - weight products is 4.73+4.36 + 22.75+34.1 = 65.94

Answer:

The student's grade is 65.94. The heavily - weighted final exam has a significant impact on the overall grade. Since the final exam has a weight of 55%, a relatively low score of 62% on the final exam pulls down the overall grade despite the higher scores on homework (94.6%) and quizzes (87.1%).
