Question

a students course grade is based on one midterm that counts as 10% of his final grade, one class project that counts as 15% of his final grade, a set of homework assignments counts as 45% of his final grade, and a final exam that counts as 30% of his final grade. his midterm score is 64, his project score is 81, his homework score is 87, and his final score is 75. what is his overall final score? what letter grade did he earn (a, b, c, d, or f)? assume that a mean of 90 or above is an a, a mean of at least 80 but less than 90 is and so on. his overall final score is (type an integer or a decimal. do not round)

Explanation:

Step1: Calculate weighted scores

Midterm: \(64\times0.1 = 6.4\)
Project: \(81\times0.15=12.15\)
Homework: \(87\times0.45 = 39.15\)
Final exam: \(75\times0.3=22.5\)

Step2: Sum up weighted scores

\(6.4 + 12.15+39.15 + 22.5\)
\(= (6.4+12.15)+(39.15 + 22.5)\)
\(=18.55+61.65\)
\(=80.2\)

Answer:

\(80.2\)
