The expected number of swimmers visiting the community pool each day determines many lifeguards are scheduled to work. \( s= \) the expected number of swimmers \( I \) = the number of lifeguards scheduled to work Which of the variables is independent and which is dependent? \( I \) is the independent variable and \( s \) is the dependent variable \( \begin{array}{l}s \text { is the independent variable and } I \text { is the dependent } \\ \text { variable }\end{array} \)

In this scenario, \( s \) is the independent variable, as the number of expected swimmers directly influences the scheduling of lifeguards. The lifeguards scheduled, \( I \), are the dependent variable because their number depends on how many swimmers are anticipated that day. It's like a game where the number of players (swimmers) determines how many referees (lifeguards) you need to keep things in check! Understanding these relationships can help pool managers efficiently allocate resources and ensure safety. For instance, if they project higher attendance on weekends, they can confidently schedule more lifeguards. This foresight not only enhances safety but also improves the overall experience for swimmers.
