Which of the following statements is not true about report styles?
Lina20 [59]

Answer:

The answer to the following question is the option "C".

Explanation:

In computer science, Report is a document that displays data in a standardized format. We can summarize the report orally but the complete reports are always given in documents. In report styles, we can select controls for formatting sources, select controls for the formatting of citations and it does not control the overall formatting of the report. So the incorrect statement to this question is "Use the Page Setup tab to choose a report style for your document".

, 13 dB correspond to a power ratio of ....?
ohaa [14]

Answer:

19.95

Explanation:

Power ratio (in db) = 10 * log [P(out)/P(in)]

Here, P(in) and P(out) correspond to input and output power in Watts respectively.

This implies, 13 db = 10 * log [P(out)/P(in)]

Rearranging,  log [P(out)/P(in)] = (13/10)

Or, P(out)/P(in) = 10 ^ 1.3 = 19.95

But, P(out)/P(in) corresponds to the power ratio of output and input power.

So the required power ratio corresponds to 19.95
