Question

dean is the manager of a restaurant and is evaluating whether or not the restaurant has enough parking spaces. at ten different times during the day, he gathered information about the number of customers in the restaurant and the number of cars in the parking lot. he represented the data with the given scatter plot and modeled the data with a linear equation. based on the model, approximately how many customers will be in the restaurant when there are 10 cars parked in the restaurant’s parking lot? a. 23 b. 17 c. 28 d. 7

Explanation:

Step1: Analyze the scatter plot

The x - axis represents the number of customers and the y - axis represents the number of cars. We need to find the value of x (customers) when y (cars) = 10.

Step2: Use the linear model (trend line)

Looking at the trend line (the blue line) in the scatter plot, when y = 10 (number of cars), we can estimate the value of x (number of customers) by looking at the corresponding x - value on the trend line. From the plot, when y = 10, the x - value (customers) is approximately 17.

Answer:

B. 17
