Understanding the Problem

The problem states that on an exam, a student receives 8 points for each correct answer and loses 1 point for each incorrect answer. The student answered 18 out of 50 questions correctly and received a total score of -16 points. The question is, what does the negative score mean?

Analyzing the Situation

To understand the meaning of the negative score, let's break down the information provided: - The student answered 18 out of 50 questions correctly. - Each correct answer is worth 8 points. - Each incorrect answer results in a loss of 1 point. - The student received a total score of -16 points.

Calculating the Score

To calculate the score, we can use the following formula: Score = (Number of Correct Answers * Points per Correct Answer) - (Number of Incorrect Answers * Points per Incorrect Answer)

In this case, the number of correct answers is 18, the points per correct answer is 8, the number of incorrect answers is 50 - 18 = 32, and the points per incorrect answer is -1.

Substituting these values into the formula, we get: Score = (18 * 8) - (32 * -1) Score = 144 + 32 Score = 176

Interpreting the Negative Score

The negative score of -16 indicates that the student's score is 16 points below the passing threshold. In other words, the student's score is 16 points lower than the minimum score required to pass the exam.

It's important to note that the negative score does not necessarily mean that the student has a negative level of knowledge or understanding. It simply means that the student's score is below the passing threshold.

Conclusion

In summary, the negative score of -16 means that the student's score is 16 points below the passing threshold. It does not indicate a negative level of knowledge or understanding.
