So, the 50 TO % of return-austomers- The percent of waiting customers is the -coordinate, while the percent of return customers is the ycoordinate. So, the table of values corresponds to the points (20,85), (35,80), (50,75), (60, 60), (70, 50), (90,32) FEEDBACK Content attribution Understand the relationship between scatter plots and tables and determine patterns Question return customers if 80% of customers wait more than Using the linear relationship graphed above, estimate the percent of 10 minutes in line Provide your answer below
