Question

The expression 2T+3F+4M+10E gives the number of points a student earns on a test when the student correctly answers T true-false questions, F fill-in-the-blank questions, M multiple-choice questions, and E extended-response questions. Which statement is NOT true?

A) The coefficient 2 indicates that each correct true-false question earns 2 points.
B) The coefficient 3 represents the points earned for each fill-in-the-blank question.
C) The term 10E represents the total number of points earned from 10 extended-response questions.
D) The term 4M represents the total number of points earned from M multiple-choice questions worth 4 points per question.

Answer 1

Answer: C) The term 10E represents the total number of points earned from 10 extended-response questions.

Explanation:

Hi, the statement c) is false, because the term 10E represents the total of points earned form E extended-response questions worth 10 points per question.

The error is that the number 10 does not represent the number of correct question; instead it represents the value per question. The number of correct questions is represented with the variable E.

Feel free to ask for more if needed or if you did not understand something.

Answer 2

C) The term 10E represents the total number of points earned from 10 extended-response questions

Explanation:

From the question;

The expression 2T+3F+4M+10E =points a earns on a test

Number of true-false questions correctly answered=2T

Number of Fill-in -the blank questions correctly answered=3 F

Number of multiple choice questions correctly answered= 4M

Number of extended-resonse questions correctly answered =10 E

However, the question does not mention the number of qusetions in each category. Like how many true-false questions were there. It only tells you the number of correct true-false qusetions that were answered. So saying that there were 10 extended-response questions is incorrect.
