Question

dave is scheduling wrestling matches for a tournament. the number of matches is determined by how many competitors are registered for the tournament.
m = the number of matches
c = the number of competitors
which of the variables is independent and which is dependent?
m is the independent variable and c is the dependent variable
c is the independent variable and m is the dependent variable

Explanation:

To determine independent and dependent variables, we analyze the relationship: the number of matches (\(m\)) depends on the number of competitors (\(c\)) (since matches are determined by competitors). An independent variable is the one that isn't determined by another in the context, and a dependent variable depends on the independent one. Here, \(c\) (competitors) is independent (its value isn't determined by matches), and \(m\) (matches) is dependent (it depends on \(c\)).

Answer:

c is the independent variable and m is the dependent variable
