Answer:
True, the relation is directly proportional.
Step-by-step explanation:
The direct proportionalty mean that ratio between the two variables is constant, that is:
[tex]k = \frac{y}{x}[/tex]
Where:
[tex]x[/tex] - Hours worked.
[tex]y[/tex] - Amount of Dirt Excavated.
[tex]k_{1} = \frac{6.6}{3}[/tex], [tex]k_{1} = 2.2[/tex]
[tex]k_{2} = \frac{6.6}{3}[/tex], [tex]k_{2} = 2.2[/tex]
[tex]k_{3} = \frac{17.6}{8}[/tex], [tex]k_{3} = 2.2[/tex]
[tex]k_{4} = \frac{19.8}{9}[/tex], [tex]k_{4} = 2.2[/tex]
SInce ratio remains is constant, the assumption is true.
