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 homework 94.6 0.05 4.73 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 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 1.00 and the sum of the grade - weight products (which is the final weighted grade) is 65.94.
