Question
d = 2,565 - 500t
An airplane flies directly from a city in Pennsylvania to a city in Ecuador. The equation above estimates the distance d, in miles, from the city in Ecuador of the airplane t hours after taking off from the city in Pennsylvania.
Which of the following is the best interpretation of the number 2,565 in this context?
- The speed, in miles per hour, of the airplane
- The distance, in miles, the airplane travels in one hour
- The distance, in miles, the airplane travels between the two cities
- The time, in minutes, it takes the airplane to reach the city in Ecuador
The correct answer is: The distance, in miles, the airplane travels between the two cities
In the equation d = 2565 – 500t
2565 is the distance between Ecuador and Pennsylvania

To determine if cooking with olive oil reduces the risk of heartburn for men, researchers interviewed a random sample of 5,500 men who had no history of ' heartburn. Study participants were identified as, either regular or occasional olive oil users. Five years later, researchers interviewed the men again. They found that the proportion of men who experienced frequent heartburn was significantly lower for men identified as regular olive oil users. Which of the following is the most appropriate conclusion of the study?
