SAT question 8156d446 (Two-variable Data Models And Scatterplots)

Question

Each dot in the scatterplot above represents the temperature and the number of people who visited a beach in Lagos, Nigeria, on one of 11 different days. The line of best fit for the data is also shown. According to the line of best fit, what is the number of people, rounded to the nearest 10 , predicted to visit this beach on a day with an average temperature of 32 °C?

College Board · Accepted Answer

The correct answer is 480. The correct answer is 480 . An average temperature of 32 ^° Celsius corresponds to the value 32 on the x -axis. On the line of best fit, an x -value of 32 corresponds to a y -value of 480 . The values on the y -axis correspond to the number of people predicted to visit this beach. Therefore, 480 people are predicted to visit this beach on a day with an average temperature of 32 ^° Celsius.

Note: The line of best fit passes through (25,80) and (32,480), so at x=32 the predicted y-value is 480.
