Iteru [2.4K]

Answer:

c. Both a and b

Explanation:

In computing, processing information simply means performing a task. It means transforming data from one form to another.

In the real sense of it, it means, performing arithmetic or logical operations (by ALU) on binary data which could result in transmitting data from input devices to output devices. When a user launches the calculator application on his PC, and he tries to do some arithmetic (which is processed by the ALU) by entering numbers using his keyboard/mouse (input devices), he gets the result on the screen(output device). This scenario is a typical example of processing information.

Consider the following code example:
yKpoI14uk [10]

Answer:

The number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.

Explanation:

This part of the code below

WHERE InvoiceTotal - PaymentTotal - CreditTotal >

(SELECT AVG (InvoiceTotal - PaymentTotal- CreditTotal)

FROM Invoices)

gives the condition to pick the invoices with balance that are greater than the average balance for all invoice.

This part of the code below

GROUP BY VendorName

ORDER BY BalanceDue DESC;

then enables the program to group the result of the above condition by VendorName and sort the resulting rows in the order of BalanceDue. You will therefore, obtain for each row in the NumberOfInvoices column, the number of invoices for each vendor that have a larger balance due than the average balance due for all invoices.
