the scatter plot shows the relationship between the test scores of a group of students and the number of hours they study in a week:
on a grid, label hours studying on x axis and test scores on y axis. the title of the graph is test scores and hours studying. the scale on the x axis shows the numbers from 0 to 10 at increments of 1, and the scale on the y axis shows numbers from 0 to 100 at increments of 10. dots are made at the ordered pairs 1.1, 10 and 2, 25 and 3.1, 10.1 and 4, 30 and 4, 45 and 5, 45 and 6, 25 and 6.5, 60 and 7, 45 and 7.5, 50 and 7.5, 75 and 8, 60 and 8.5, 75 and 9, 60. the ordered pair 1, 100 is circled and labeled as m. all the other points are put in an oval and labeled as n.
part a: what is the group of points labeled n called? what is the point labeled m called? give a possible reason for the presence of point m. (5 points)
part b: describe the association between students' test scores and the number of hours they study. (5 points)

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
