Final answer:
For parking on a one-way street, you must be parked no more than 18 inches from the curb. When estimating the number of crookedly parked cars out of 22, 37.5% equates to about 8.25 cars expected to be parked crookedly. The probability of at least 10 cars being parked crookedly requires further probability calculations.
Step-by-step explanation:
To answer the first question regarding parking on a one-way street, the distance from the curb within which you may park your vehicle is 18 inches (A). This is a standard regulation in many places to ensure that parked vehicles do not obstruct traffic and that there is enough room for other road users to navigate safely.
For the probability question provided, we start with the information that 37.5 percent of the cars in the De Anza parking garage are parked crookedly on any given day. In a random survey of 22 cars, the expected number of cars parked crookedly would be 22 multiplied by 37.5 percent, which equals 8.25 (A).
The question of finding the probability that at least 10 of the 22 cars are parked crookedly would involve more complex probability calculations, including the use of binomial probabilities or normal approximation, which is beyond the information given in the question. Therefore option B (0.1607) could be part of such probability assessment but we cannot confirm this without the calculations or additional context.
