Readiness Check: Modeling and Analysis of Bivariate Data Question 4 The cost in dollars \( C(x) \), where \( x \) is the number of miles driven, of renting a car for a day is \( C(x)=0.45 x+35 \). (a) Which of the following best describes the dependent variable in this model? Select an answer (b) Which of the following best describes the independent variable in this model? v Select an answer Cost Miles sulmit

The equation \( C(x) = 0.45x + 35 \) tells us that the cost of renting the car depends on the number of miles driven. This means that as you drive more miles, the cost increases based on the given rate per mile. Therefore, the dependent variable here is the cost, which varies with the miles driven. In this context, the independent variable is the number of miles driven. You can think of it as the variable you have control over; in this case, the more miles you decide to drive, the more the cost will change according to the equation. So, miles are your independent variable and play a crucial role in determining the total cost. Keep those concepts in mind as you delve deeper into modeling and analyzing bivariate data! Understanding how variables interact with each other is key to making informed decisions, especially in real-world applications like budgeting for a trip.
