Which of the following statements will ivoke the function get_course and store the reutrn values correctly? A. get_course(course

Sergio039 [100]

Answer:

Option D is the correct answer for the above question

Explanation:

Missing code: The function code is missing in the question, which defined the two return value.

Detailed Expalanation:

The above question code is in python language, which returns the two values. So there are needs of two variable which is needed to hold the returned value from a function.
Options b and c both states the two variable for the calling function which needs to hold the returned value and the option D states both option, hence it is a correct option while the other is not because:-
Option a states no variable which can hold the returned value.

A solid weighs 20gf in air and 18gf in water .find the specific gravity of the solid

swat32

<h2>Answer:</h2>

10

<h2>Explanation:</h2>

Specific gravity (also called relative density) is the ratio of the density of an object (or substance) to the density of a reference substance (mostly water). It has no unit and is given by the following;

Specific gravity = $\frac{density-of-object}{density-of-water}$

Specific gravity is also given by the ratio of the weight of the object in air to the loss of weight of the object in water. i.e

Specific gravity = $\frac{weight-of-object-in-air}{loss-of-weight-in-water}$ --------------(* * *)

In this case;

i. The object is the solid which has a weight of 20gf in air.

ii. The loss of weight of the solid in water is the difference between the weight in air (20gf) and the weight in water (18gf).

Therefore the loss of weight is

20gf - 18gf = 2gf

Now substitute these values from (i) and (ii) into equation (* * *) as follows;

Specific gravity = $\frac{20gf}{2gf}$

Specific gravity = 10

Therefore the specific gravity of the solid is 10

Problem (Commands): Let c be a copy flag and let a computer system have the set of rights {read, write, execute, append, list, m

dlinn [17]

Answer:

Aee explaination

Explanation:

1.

command copy_all_rights(p,q,s)

if read in a[p,s]

then

enter read into a[q,s];

if write in a[p,s]

then

enter write into a[q,s];

if execute in a[p,s]

then

enter execute into a[q,s];

if append in a[p,s]

then

enter append into a[q,s];

if list in a[p,s]

then

enter list into a[q,s];

if modify in a[p,s]

then

enter modify into a[q,s];

if own in a[p,s]

then

enter own into a[q,s];

end

2.

command copy_all_rights(p,q,s)

if own in a[p,s] and copy in a[p,s]

then

enter own into a[q,s];

if modify in a[p,s] and copy in a[p,s]

then

enter modify into a[q,s];

if list in a[p,s] and copy in a[p,s]

then

enter list into a[q,s];

if append in a[p,s] and copy in a[p,s]

then

enter append into a[q,s];

if execute in a[p,s] and copy in a[p,s]

then

enter execute into a[q,s];

if write in a[p,s] and copy in a[p,s]

then

enter write into a[q,s];

if read in a[p,s] and copy in a[p,s]

then

enter read into a[q,s];

delete copy in a[q,s];

end

3.

"q" would be the effect of copying the copy flag along with the right, because q would have copy right to transfter to another, which may not be intended.

_____ refers to the busiest calling hour of the day, week, month or year. And _____ refers to the average length of time the sub

Butoxors [25]

Answer: a) busy hour b) Average handle time.

Explanation:

a) In order to design a telephony circuit, trunk, or call center, it is needed to take into account the busiest calling hour (as a "sliding" 60-minute period) in one day, or week, month or year, generally calculated as an average.

This period is called the "busy hour" and is used to compute the traffic intensity, in Erlangs, considering that if the circuit is busy 100% of the time during 3600 seconds, it will be cursing 1 Erl of traffic.

This traffic can result from 60 calls of 1 min each, 36 calls of 100 sec each, or any combination that have the same outcome of 1 Erl.

b) In order to define, for instance, the number of employees in a call center, a very important parameter is the average time used for each call, adding the queuing time, the true talk time and any other time needed to set up a successful call, i.e., the time that the subscriber stays on the phone after putting the call.

This time is known as AHT (Average Handle Time).
