Answer:
A general understanding that abstraction allows programmers to hide details By hiding details, programmers are able to work with complex systems in small pieces without having to pay attention to every detail at once An explanation of how top down design implements abstraction
Example:
Through the use of abstraction, a programmer is able to take one large idea, and break it down into smaller pieces. In the context of top-down design, this means that the programmer can create one function that is made up of a set of smaller sub functions. After determining the details of those sub functions, the programmer no longer needs to take into account how they work, knowing that they will work in when called. For example when drawing a snowflake, the programmer may use top down design to split it into separate branches. Each of those branches may have sub functions that determine the detail to be repeated. This allows programmers to develop complex systems while managing complexity at multiple levels of abstraction.
Which of the following is FALSE about event-driven programs?
A. Event-driven programs do not implement algorithms.
B. Some portions of an event-driven program may never execute while the program is running.
C. An event-driven program is written to respond to specified events by executing a block of code or function associated with the event.
D. The order in which an event-driven program will run cannot always be known ahead of time. E. Event-driven programs can be run multiple times with different outcomes, based on user interactions.
Answer:
B. Cash, accounts receivable, inventories, prepaid items.
Explanation:
In the balance sheet, assets are presented in an orderly manner guided by the amount of time they take to convert into cash. Assets requiring the shortest time to convert into cash will appear first. Cash will always be on top as it does not require conversion.
Goodwill comes last as the business will have to be sold for it to turn into cash.
- In the list provided, cash will appear first.
- Accounts receivable is money a business expects to receive from customers for goods or services provided. In practice, the money should be received within 60 days
- Inventories in assets refer to finished goods in the store. They are awaiting sales. Inventories will take longer as stocks have to be sold and become account receivable before converting to cash.
- Prepaid items are expenses paid before their due date. They appear in the balance sheet as cash assets because they have not been consumed. The expectation is that they will be utilized within the current year. Converting into cash them will require getting a refund from the recipient of the funds, which could be a lengthy process.
Answer:
These are the answer choices for the question:
Students do not have good nutritional information.
Soda purchases represent a large fraction of students' budgets.
There are few other places to purchase soda on campus.
The price elasticity of demand for soda is equal to 1.
And this is the correct answer choice:
There are few other places to purchase soda on campus.
Explanation:
If vending machines raise the price of soda by two, by the still sell almost the same amount, this means that they have a monopoly over the selling of soda in campus, and that students continue to buy there because they do not have any other feasible alternatives.
This is the problem with monopolies: they can charge very high prices and still make a profit because they will always have demand, but this very act makes consumers worse off, and reduces general social welfare.
Answer: 6%
Explanation:
Based on the information given, when the flotation costs is ignored, the company's cost of preferred stock will be calculated thus:
Cost of preferred stock = Dividend on preferred stock / Price of preferred stock
Cost of preferred stock = 4.5/75 = 0.06 = 6%
Therefore, the cost of preferred stock is 6%.
