Normalize the following relation:

lora16 [44]

Answer:

Hi Riahroo! This is a good question on the concept of relational databases.

We can normalize the relations as follows:

Flight

(flightnumber (unique), flighttime, airline_id, departure_city, arrival_city, passenger_id, pilot_id, airplane_id)

has_one_and_belongs_to :airline

has_many :passengers

has_one :pilot

Itinerary(passenger_id, flight_id)

Belongs_to

Passenger_details

(passengername (unique), gender, date_of_birth)

has_many :flights

Pilot

(pilotname (unique), gender, date_of_birth)

has_many :flights

airline(airlinename)

airplane(planeID, type, seats))

Explanation:

To normalize a relation, we have to remove any redundancies from the relationships between database objects/tables and simplify the structure. This also means simplifying many-to-many relationships. In this question, we see there is a many-to-many relationship between flights and passengers. To resolve this we can introduce a join table which simplifies this relationship to a one-to-many between the objects.

In Coral programming: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. C

viva [34]

Answer:

Yes, it will be after 6 hours: 50 mg, after 12 hours: 25 mg, and after 18 hours: 12.5 mg

Explanation:

Remember coral is a functional programming language and follows Pythons functional programming paradigm. Remember Python supports functional, imperative as well as OOPS paradigm.

The function will be:

def void calcamtleft(int amt):

integer a=6

integer time=6

integer i=1

while amt> 0:

amt=amt/2

print("After"+time+" hours:" +amt+"mg")

i++

time=a* i

Hence in first loop amt=100

new amt=100/2=50

After 6 hours: 50 mg ( this will be printed)

i will increment then, and time will be = 6 *2 =12

now input amt=50

new amt=50/2=25

After 12 hours 25 mg (this will be output)

i will increment then, and time will be = 6 *3 =18

now input amt=25

new amt=25/2=12.5

After 18 hours 12.5 mg (this will be output)

i will increment then, and time will be = 6 *4 =24

now input amt=12.5/2= 6.25

new amt=6.25/2= 3.125

After 24 hours 3.125 mg (this will be output)

i will increment then, and time will be = 6 *5 =30

now input amt=3.125

new amt=3.125/2= 1.5625

After 30 hours 1.5625 mg

And this will continue till amt>0

netineya [11]

A radiologist’s computer monitor has higher resolution than most computer screens. Resolution refers to the: <u>number of horizontal and vertical pixels on the screen.</u>

<u>Explanation:</u>

The resolution of a screen refers to the size and number of pixels that are displayed on a screen. The more pixels a screen has, the more information is displayed on it without the user having to scroll for it.

More pixels also define and enhance the clarity of the pictures and content displayed on the screen. Pixels combine in different ratios to provide different viewing experiences for users.

List and describe with details at least three approaches to selecting processes from priority-based multi-level queues.

garik1379 [7]

Based on the information given, it is important to give higher priority to the queue that contains the high priority thread.

<h3></h3><h3>What is the Important Fact?</h3>

A lot of interrupts can take place at any time, and due to that, they cannot always be ignored as the part of code affected by interrupts need to be guarded from constant use.
So, the load-balancing requirements for keeping about the same number of threads would need to be taken or retained and the important case of top priority thread would also be kept.
An priority-based scheduling algorithm can handle this situation if one run queue had all high-priority threads and a second queue had all low-priority threads because if giving greater priority to the two queue that has the national priority comment section as well as, so, first method is the thread in all of the queue.
Multi-level queue scheduling algorithm is used in scenarios where the processes can be classified into groups based on property like process type, CPU time, IO access, memory size, etc. One general classification of the processes is foreground processes and background processes.
