Q. Rosa works for a small company that sells books online and is responsible for mailing out the books to customers. Every morning she gets in line at the local post office and estimates the length of her wait. The length of her wait depends on the number of people in line ahead of her.\newlineww = the length of time Rosa will need to wait\newlinepp = the number of people in line ahead of Rosa\newlineWhich of the variables is independent and which is dependent?\newlineChoices:\newline(A) pp is the independent variable and ww is the dependent variable\newline(B) ww is the independent variable and pp is the dependent variable
  1. Identify Variables: Identify the variables and their roles in the scenario:\newlineRosa's waiting time ww depends on the number of people pp in line ahead of her. Therefore, pp is the variable that influences ww.
  2. Define Variables: Define the independent and dependent variables:\newlineThe independent variable is the one that influences the other variable without being affected by it. In this case, pp (the number of people in line) is the independent variable because it determines the length of Rosa's wait. The dependent variable is ww (waiting time), as it depends on pp.
  3. Match Correct Choice: Match the correct choice based on the definitions:\newlineSince pp is the independent variable and ww is the dependent variable, the correct choice is (A) pp is the independent variable and ww is the dependent variable.
