Final answer:
To determine the number of accessible parking spaces needed in a parking structure, guidelines like the ADA Standards for Accessible Design are typically followed, but specifics are not given in the question. Probabilities involving parking times can be calculated using the properties of a normal distribution. Potential energy of a parked car can be found using the formula for potential energy, considering the mass of the car and the height of the parking level.
Step-by-step explanation:
The number of accessible parking spaces required in a parking structure is typically determined by legal requirements and guidelines which specify ratios or percentages based on the total number of spaces. However, as this information is not provided in the question, a specific number cannot be concluded without additional context. That said, it is common for parking structures to follow the Americans with Disabilities Act (ADA) Standards for Accessible Design, which outlines minimum requirements.
In addition, when considering the length of time it takes to find a parking space being normally distributed with a mean of five minutes and a standard deviation of two minutes, we can approximate probabilities for various time intervals. For instance, using a standard normal distribution table or a calculator with statistical functions, one could calculate the likelihood that it takes less than one minute or more than a certain number of minutes to find a parking space.
Regarding the probability calculations based on cars parked crookedly, one can apply binomial probability formulas or use a binomcdf function on a scientific calculator to find the probability that at least a certain number of cars out of a sample are parked crookedly.
Finally, to calculate potential energy, one would use the formula Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h). For an automobile of mass 1360 kg parked at a height of 36.6 m, the potential energy can be calculated by substituting the values into the formula.
