Final answer:
Your grade would be 90% if you got 45 out of 50 questions correct on your paper. You calculate this by dividing the number of correct answers by the total number of questions and then multiplying by 100.
Explanation:
If you got 45 out of 50 questions correct on a test, to find your grade as a percentage, you would divide the number of questions you got right (45) by the total number of questions (50) and then multiply the result by 100 to convert it to a percentage. The calculation would be as follows:
(45/50) x 100 = 90%
So, the correct answer to the question 'Your paper says that you got 45 of 50 questions correct. What is your grade expressed as a percentage?' is c. 90%.
Percentage composition is often used to describe such scores. As referenced earlier, probabilities and percentiles can play a significant role in educational assessments; however, they are not directly applicable to this particular question.
