1. Your physics professor told you that you feel heavier or lighter in an elevator at the beginning or end of your vertical voyage. You want to test if your weight ACTUALLY changes, so you take a bathroom scale with you to the rickety elevator in Elings hall. You hop on at the second floor and step onto the scale before pressing the button to travel down to the first floor. Before the doors close, while the elevator isn’t moving, you have a weight of . As soon as the elevator starts downward, the scale reads . What is the magnitude of the acceleration of the elevator?

7A. Construct a market for apartments in an urban area with no more available land for housing development. Assume demand has some elasticity but supply is perfectly inelastic. 7B. Change the market for apartment in 7A and show changes to price and quantity if the government establishes a rent ceiling that is below the equilibrium price. Identify new price and quantity with subscript 2. 7C. Define the term social efficiency. Explain whether the established rent control price ceiling is socially efficient if rent control allowed low-income families to have affordable housing.

Explain your answer e How does the Apriori algorithm improve upon the brute-force algorithm? f) We generally will be more interested in association rules with a high confidence threshold.However,often we will not be interested in association rules that have a confidence of 100%Why?Explain your answer

Write a code that validates user inputs. First, create a program that lists the menu of the drinks you sell. It then asks users to input the drink they want to order. After submitting an order, your program confirms the order with the user. Create a menu that is the same as below. When typing the number in "please enter your order (1- 4)", there will be a confirmation. [MENU] 1. Frappuccino 2. Cafe Latte 3. Cafe Americano 4. Cafe Macchiato Please enter your order (1-4): 4 You've ordered Cafe Macchiato. Your order will be ready soon. Make sure you validate user inputs in the code: User input should not be empty. User input has no ValueError (the input can be converted to an integer). User can only input 1, 2, 3, or 4.
