The piracy of music and movies is often evident on file-sharing services that use the _________ protocol./11252180/4869941c?utm_

Eva8 [605]

Answer:

BitTorrent protocol

Explanation:

BitTorrent is a system that allows the sharing of almost any file over the internet, being mainly used for the distribution of videos, music and software. It is quite popular because it is an easy tool to use and at the same time very efficient.

BitTorrent itself is actually a data sharing protocol and not a centralized system. There is no server providing the data, but a standard of communication between multiple computers that allows files to be located, distributed and retrieved by all. This protocol is very much used for pirate sharing of music and movies.

Sandra drew an isosceles triangle that has an angle that measures 46 degrees. Which could be the measures of the other two angle

kipiarov [429]

Answer:

46 and 88° or 67 and 67°

Explanation:

An isosceles triangle has two sides of equal length and one other of a different length;

A triangle with such features also has 2 equal angles and one other;

If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;

All angles in a triangle sum to 180, so:

180 - 46 = 134

The two remaining angles constitute 134° collectively;

If they are equal, each angle can be found like so:

¹³⁴/₂ = 67

Each of the two equal angles will be 67°;

Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92

Then, the remaining angle can be found like so:

180 - 92 = 88

So the angles within the triangle are either:

46, 46 and 88°

or

46, 67 and 67°

Consider the following hypothetical population and compute the statistical measures below: #births = 50,000; #deaths = 10,000; #

777dan777 [17]

Answer:

The birth rate refers to an average number of births in one year per thousand individuals in the population at mid-year.

BR = (total birth in an annum / total population in mid year) * 1000

BR = (50000 / 1000000) * 1000 = 50

Death rate refers to an average number of death in an annum per thousand individuals in a population at mid year. Thus,

DR = (total death / total population in mid year) * 1000

DR = (10000 / 1000000) * 1000 = 10

Annual population growth rate or APGR is calculated as:

APGR = (Birth rate - Death rate) / Death rate

APGR = (50 - 10) / 10 = 4.0 %

Doubling time is the whole sum time needed for a population to get double in size. It is calculated as DT = ln (2) / growth rate

70 / 4.0 = 17.5 years

Thus, population will get double in 17.5 years.

Adjusted (true) growth rate is equal to APGR + (NMR / Death rate)

And NMR = [(immigrants -emigrants) / total population] * 1000

NMR = [(5000 - 20000) / 1000000] * 1000 = -15

Thus, Adjusted (True) growth rate = 4.0 + (-15 /10) = -6%

The adjusted (true) doubling time = ln (2) / Adjusted growth rate

= 70 / -6 = -11.66

This negative sign shows that it will never get double in such situation.
