Anand's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y, equals, 7, point, 2, x, plus, 55y=7.2x+55, where yy represents the expected quiz score and xx represents hours spent on homework that week. What is the meaning of the xx-value when y, equals, 77y=77? Answer Multiple Choice Answers The number of hours a student should spend on their homework to expect a score of 77 on the quiz. A student's expected quiz score if they spent 77 hours on their homework. The change in expected quiz score for every additional one hour students spend on their homework.

The number of hours a student should spend on their homework to expect a score of 77 on the quiz.
Explanation: When y = 77, the equation becomes 77 = 7.2x + 55. Solving for x, we get x = 3.75. So, the xx-value represents the number of hours a student should spend on their homework to expect a score of 77 on the quiz.
