b) 12 cars
c) 18 cars
d) 24 cars

Answer 1

To find the number of cars that drove over 65 mph, we can first calculate the number of cars that exceeded the 55 mph speed limit by more than 10 mph. The number of cars that drove over 65 mph is a) 6 cars.

Step-by-step explanation:

To find the number of cars that drove over 65 mph, we can first calculate the number of cars that exceeded the 55 mph speed limit by more than 10 mph.

We know that 0.75% of the 800 cars exceeded the speed limit, so that would be 0.0075 * 800 = 6 cars.

Out of these 6 cars, we need to find the number of cars that drove over 65 mph. Since all these cars exceeded the speed limit by more than 10 mph, we can conclude that all 6 cars drove over 65 mph.

Therefore, the answer is 6 cars.
