Final answer:
The correct distance for parallel parking near a curb is typically within 18 inches, but it's important to check local regulations.
Step-by-step explanation:
The correct answer to the question about the general rules for parallel parking is that a vehicle should be parked within 18 inches of the curb. However, the exact distance may vary by local laws so it's always best to check with your city's parking regulations.
The given information about the De Anza parking garage does not directly answer the parking distance question, but it provides statistical data about how cars are parked.
For question 8, using the provided information, we can calculate that on any given day, 37.5 percent of the cars parked in the De Anza parking garage are parked crookedly. For every 22 cars, the expected number of cars parked crookedly would be 8.25 (which is 37.5% of 22).
The question regarding the probability that at least 10 of the 22 cars are parked crookedly requires calculations using the binomial or normal approximation to the binomial distributions. The exact answer is not provided here, but this would be a statistics problem where you could apply formulas or statistical software to determine the probability.
When parallel parked, you should be within 6-12 inches of the curb. This distance allows for enough space to maneuver out of the parking space while still keeping the vehicle close enough to the curb to avoid obstructing traffic. It is important to note that parking laws can vary by location, so it's always a good idea to check local regulations for specific guidelines.
The statistical problem provided with the De Anza parking garage suggests 37.5% of 22 surveyed cars are parked crookedly, which is 8.25 cars. The probability question requires statistical calculations.
