Question

tessas class had a math exam where the grades were between 0 and 10.
n(g) models the number of students whose grade on the exam was g.
what does the statement ( n(8)>2cdot n(5) ) mean?
choose 1 answer:
a the number of students whose grade was 8 is more than twice the number of students whose grade was 5.
b the number of students whose grade was higher than 5 is greater than the number of students whose grade was 5 or lower.
c there are 8 students whose grade was higher than twice the grade of another group of 5 students.

Explanation:

Given that \(N(g)\) represents the number of students with grade \(g\). The expression \(N(8)\) is the number of students with grade \(8\), and \(2\cdot N(5)\) is twice the number of students with grade \(5\). The inequality \(N(8)>2\cdot N(5)\) means we are comparing these two quantities.

Answer:

A. The number of students whose grade was 8 is more than twice the number of students whose grade was 5.
