- A city's transportation committee has conducted research on traffic and car accidents for downtown streets. There is a 9% chance of being involved in a car accident when 15 or more cars are driving on Johnson Street and a 7.5% chance when 20 or more cars are driving on Dublin Street. The two streets intersect to form a risk area with a radius of 0.1 mi. Approximate the density of cars per square mile in the risk area when 17 cars are on Johnson Street and 21 cars are on Dublin Street. Use 3.14 for pi. There are approximately 1,210 cars per square mile in the risk area. There are approximately 2,674 cars per square mile in the risk area. There are approximately 2,165 cars per square mile in the risk area. There are approximately 1,082 cars per square mile in the risk area.The figure above shows three different panels examining the relationship between average price and type of avocado.a)Compare the distributions of the average prices for the conventional and organic avocados.
