Question

A teacher notices a correlation between students’ scores on homework assignments and their scores on corresponding quizzes. The line of best fit for the data is given by the formula q=1.2h−25 , where h is the student homework score and q is the student quiz score. Which of the following relates the domain of this function to this scenario? (Assume that the homework does not have extra credit).(1 point) Responses [0,1.2] left bracket 0 comma 1.2 right bracket [0,100] left bracket 0 comma 100 right bracket [−25,25] left bracket negative 25 comma 25 right bracket [50,90]

Answer 1

In the context of this scenario, the homework scores (h) are typically within the range of 0 to 100, as most grading scales define homework scores on a scale from 0 (lowest possible score) to 100 (highest possible score).

The function for the quiz score, given by the equation \( q = 1.2h - 25 \), will output quiz scores based on these homework scores. However, since the homework scores do not allow for extra credit, we can conclude that the lowest score is 0 and the highest score is 100.

Therefore, the appropriate domain for the homework scores (h) would be:

[0, 100]

Given the responses, the correct answer would be:

[0, 100] (left bracket 0, 100 right bracket).
