Question

a student has the following averages. homework: 94.6% mid - term: 65% quizzes: 87.1% final exam: 62% find the students grade assuming these weights: homework (5%), quizzes (5%), mid - term (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 homework 94.6 0.05 4.73 quizzes 87.1 0.05 4.36 mid - term 65 0.35 22.75 final exam 62 0.55 34.1 sum = sum =

Explanation:

Step1: Calculate sum of weights

The weights are 0.05 (homework), 0.05 (quizzes), 0.35 (mid - term), 0.55 (final exam). The sum of the weights is $0.05 + 0.05+0.35 + 0.55=1$.

Step2: Calculate sum of grade - weight products

The grade - weight products are 4.73 (homework), 4.36 (quizzes), 22.75 (mid - term), 34.1 (final exam). The sum of the grade - weight products is $4.73+4.36 + 22.75+34.1 = 65.94$.

Answer:

The sum of the weights is 1 and the sum of the grade - weight products (which is the student's final grade) is 65.94.
