5.
a.
b.
c.
in problem 2, the number of downloads, which is on the vertical axis of each graph,
depends on the day, which is on the horizontal axis. when one quantity depends on
another, show the independent quantity on the horizontal axis and the dependent
quantity on the vertical axis.

Explanation:

Step1: Analyze the trend of graph 3

Graph 3 shows a decreasing trend. Looking at the tables:

• Table A: Temperature values \(91^{\circ},89^{\circ},81^{\circ},64^{\circ}\) (difference between \(91 - 89=2\), \(89 - 81 = 8\), \(81-64 = 17\))
• Table B: Temperature values \(61^{\circ},60^{\circ},59^{\circ},58^{\circ}\) (difference between \(61 - 60=1\), \(60 - 59 = 1\), \(59-58 = 1\))
• Table C: Temperature values \(24^{\circ},26^{\circ},27^{\circ},21^{\circ}\) (not a strictly decreasing trend)

Table A has a non - uniform decreasing trend.

Step2: Analyze the trend of graph 4

Graph 4 has a non - uniform trend (not a simple linear decrease).

• Table C: \(24^{\circ}\) at \(1\) P.M., \(26^{\circ}\) at \(3\) P.M., \(27^{\circ}\) at \(5\) P.M., \(21^{\circ}\) at \(7\) P.M. (first increasing then decreasing)

Step3: Analyze the trend of graph 5

Graph 5 has a nearly uniform decreasing trend.

• Table B: Temperature values \(61^{\circ},60^{\circ},59^{\circ},58^{\circ}\) (uniformly decreasing by \(1^{\circ}\) each time - interval)

Answer:

3 - A, 4 - C, 5 - B
