Q. Tessa's class had a math exam where the grades were between 00 and 1010.\newlineN(g)N(g) models the number of students whose grade on the exam was gg.\newlineWhat does the statement N(8)>2N(5)N(8) > 2 \cdot N(5) mean?\newlineChoose 11 answer:\newline(A) There are 88 students whose grade was higher than twice the grade of another group of 55 students.\newline(B) The number of students whose grade was 88 is more than twice the number of students whose grade was 55.\newline(C) The number of students whose grade was higher than 55 is greater than the number of students whose grade was 55 or lower.
  1. Understanding N(g): Understand the function N(g).\newlineN(g) is a function that models the number of students who received a grade of g on the math exam. The variable g represents the grade, which can range from 00 to 1010.
  2. Interpreting N(8) > 2 \cdot N(5): Interpret the statement N(8) > 2 \cdot N(5).\newlineThe statement N(8) > 2 \cdot N(5) means that the number of students who received a grade of 88 is greater than twice the number of students who received a grade of 55.
  3. Matching the interpretation: Match the interpretation to the given choices.\newlineBased on the interpretation in Step 22, we can see that the correct choice is:\newline(B) The number of students whose grade was 88 is more than twice the number of students whose grade was 55.
