Relating Relationships Shown in Tables to Equations

Question 9 • FL-1205010-M/J Grade 6 Mathematics B -GF

The table shows the relationship “Kevin read 35 pages per hour.” Hours (h)Pages (p)135270310541405175Which statements are correct? Check all that apply.

Answer
A
The variable h is the independent variable.
B
The variable p is the independent variable.
C
The number of pages read increases as the amount of time decreases.
D
The number of hours spent reading causes a change in the number of pages read.
E
The variable p is the dependent variable.
F
The variable h is the dependent variable.
G
The more pages that are read, the less time it takes.

Explanation

The number of pages Kevin reads is 35 times the number of hours: for example, 2 hours gives 70 pages. The hours, h, are the independent variable because they determine how many pages are read; the pages, p, are the dependent variable. Spending more hours reading leads to more pages, so the statements claiming that pages increase as time decreases or that more pages take less time are incorrect.
