Answer: C) a 10 percent increase in efficiency of sales of a particular product line over one year
The term "quantifiable" means that we can attach a number to it. Specifically, a number in which we can do math operations upon it. Something like telephone numbers or serial numbers don't really count as quantifiable entities. They are qualitative variables instead. So you have to be careful what numbers you run into. In this case, "10 percent increase in efficiency" is quantitative and fits what we're after.
A 10% increase corresponds to the multiplier 1.10; for instance, if you had sales of 40 million dollars one year, then a 10% increase is 1.10*40 = 44 million in sales. This is one example where we apply a math operation (specifically multiplication) on the value in question.
Answer:
to remind of purpose and use
Explanation:
When a data item has a meaningful name, the name can be a reminder of the purpose and use of the item. It can also be suggestive of the range of legitimate values. It also makes error-checking easier.
If the name of it is not meaningful, this information about the item must be found in a dictionary somewhere, often a time-consuming or difficult project. Using elements with non-meaningful IDs provides opportunities for error and confusion--not something that is generally wanted.
An analogue sound wave is picked up by a microphone and sent to an Analogue to Digital (ADC) converter in the form of analogue electrical signals. The ADC converts the electrical signals into digital values which can be stored on a computer. Once in a digital format you can edit sounds with programs such as audacity.
This is true, because the first page would not be the cover page.
Answer:
Asynchronous modem
Explanation:
In an asynchronous modem, data is transmitted in an infrequent stream of small packets, in which a start bit at the front signals the start of a unit, and the end of the unit is signaled by a stop bit at the back.
