The expected number of swimmers visiting the community pool each day determines how many lifeguards are scheduled to work.
s = the expected number of swimmers
l = the number of lifeguards scheduled to work
Which of the variables is independent and which is dependent?
s is the independent variable and l is the dependent variable
l is the independent variable and s is the dependent variable
In this scenario, the expected number of swimmers (s) is the independent variable, and the number of lifeguards scheduled to work (l) is the dependent variable.
Explanation: The expected number of swimmers influences how many lifeguards are needed; therefore, the number of lifeguards depends on the number of swimmers. Since the lifeguard schedule is based on the number of swimmers, we say that s is independent (it can change without being affected by l), and l is dependent (it relies on the value of s).
