Question

(a) lena works at a water park. she notices that the daily high temperature affects the daily number of tickets sold at the park as in the table below. identify the independent and dependent variables. independent variable: (choose one) dependent variable: (choose one) (b) a company that makes plastic knives is looking at its weekly sales. the graph below shows how the number of knives sold is affected by the price per knife. identify the independent and dependent variables. independent variable: (choose one) dependent variable: (choose one)

Explanation:

• For part (a): The daily high temperature (\(x\)) is what is being manipulated or changed, and it affects the daily number of tickets sold (\(y\)). So, the independent variable is the one that is changed (the cause), and the dependent variable is the one that is affected (the effect).
• For part (b): The price per knife is what the company can set (the independent variable), and it affects the number of knives sold (the dependent variable).

Answer:

• (a) Independent variable: Daily high temperature in \(^{\circ}C\); Dependent variable: Daily number of tickets sold
• (b) Independent variable: Price per knife (cents); Dependent variable: Number of knives sold
