Question

Enter a number rounded to one decimal. The syllabus states that a midterm test will count for 30% of a student's course grade. The midterm is the first graded test in the course. After the midterm, three more tests-including the final-are scheduled. The final test counts for 50% of the student's course grade and the remaining tests count equally toward the final grade. Any bonus on a test is added to the test score before the result is entered into the grade formula. A = 90 - 100 B = 80 - 89 C = 70 - 79 D = 60 - 69 F = < 60 A student scored a 62 on her midterm, a 70 on her final, and an 69 respectively 71 on both remaining exams. Her final grade was Deidre scored a 74 on her midterm and a 89 on her final. She needs to score a perfect 100 on both tests and receive a combined bonus of points on both tests to score an "A" as her final grade.

Answer 1

Weightage for each of the two tests after mid-term =

100-30-50 2 10%

a)

Final score = $0.3(62)+0.5(70)+0.1(69)+0.1(71)=67.6$

So, Final grade = D

b)

Final score = $0.3(74)+0.5(89)+0.1(100)+0.1(100)=86.7$

At least a score of 90 is required to get an A.

So, bonus required = 90-86.7 = 3.3
