(a) Explanation From Figure 5.18, we know that 58% of students took out loans for educational expenses. Thus, number of first-year college students, who have taken loans to help pay off their education are calculated as: 58 % of 500 = 58 100 × 500 = 0 (b) To determine To explain: If you can conclude that some students who are satisfied with their coursework also text in class.

Students have asked these similar questions

Describe a three step process you choose to determine how many elementary schools there are in the city of 5 million people.

A circle of radius r centered at the point (0,r) in the plane will intersect the y-axis at the origin and the point A=(0,2r), as pictured below. A line passes through the point A and the point C=(11/2,0) on the x-axis. In this problem, we will investigate the coordinates of the intersection point B between the circle and the line, as 1 → ∞ A=(0,2r) B (0,0) (a) The line through A and C has equation: y= 2 117 x+27 (b) The x-coordinate of the point B is 4472 121,2 +4 40 (c) The y-coordinate of the point B is +27 121 44 (d) The limit as r→ ∞ of the x-coordinate of B is 121 (if your answer is oo, write infinity).
