Total family income is first classified by it's four major source, earings of a male head , earings of a wife or female head , earings of a family members , and property or transfer income.

Answer:

Explanation:

a. In this scenario, the best solution would have an Object of Traditional Books, CD, Music, Bookstore and Customer.

b. All five objects would be able to be called by the main program loop and the Customer Object would call upon and use either the Books or CD object, While the Bookstore object would call upon all of the other objects.

c. Both the Bookstore object and Customer object will "have" other objects as the Bookstore needs to hold information on every Book or CD in the Inventory. While the Customer object would call upon the Book and CD object that they are purchasing.

d. The Music Object will extend the CD object and use information on the CD object as its parent class.

e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.

System testing is a crucial stage where the software design is implemented as a collection of program units.

Unit testing plays a vital role during this phase as it focuses on validating each unit's compliance with its specifications. Unit testing entails testing individual units or components of the software to ensure their functionality, reliability, and correctness.

It involves executing test cases, evaluating inputs and outputs, and verifying if the units perform as expected. By conducting unit testing, developers can identify and rectify any defects or issues within individual units before integrating them into the larger system, promoting overall software quality.

Answer:

Supplicant's Private Key

Explanation:

The supplicant uses its PRIVATE KEY to encrypt the challenge message before sending it to the verifier.

This is evident in that in a Digital Certificate Authentication, concerning challenge-response, when the verifier sends a challenge message to the supplicant, the supplicant would encrypt the challenge message with its PRIVATE KEY and send the response message back to the verifier. In return, the verifier would decrypt the response message with the true party’s public key.

Without proper synchronization, corrupted data is possible due to the fact that a shared datum can be accessible by multiple processes.

Data synchronization simply means the idea of keeping multiple copies of dataset in coherence with one another in order to maintain data integrity. It's the process of having the same data in two or more locations.

Without proper synchronization, corrupted data is possible because a shared datum could be accessed by multiple processes without mutual exclusive access.

The clock cycle time in a pipelined and non-pipelined processor will be 350ps and 1250ps respectively.

1. The clock cycle time in a pipelined processor will be the slowest instruction decode which is 350ps. The clock cycle time in a non-pipelined processor will be:

= 250 + 350 + 150 + 300 + 200

= 1250ps

2. The total latency of an LW instruction in a pipelined processor will be:

= 5 × 350 = 1750ps.

The total latency of an LW instruction in a non-pipelined processor will be:

= 250 + 350 + 150 + 300 + 200

= 1250ps

3. Based on the information asked, the stage to be split will be the cycle time. Now, the new cycle time will be based on the longest stage which will be 300ps.

4. It should be noted that the store and load instruction is used for the utilization of memory. The load instruction is 20% of the time while the store instruction is 15% of the time. Therefore, the utilization of data memory will be:

= 20% + 15% = 35%

5. The utilization of the write-register port of the "Registers" unit will be:

= 20% + 45% = 65%

6. The multi cycle execution time will be:

= (5 × 20%) + [4 × (45% + 20% + 15%)]

= (5 × 0.2) + (4 × 0.8)

= 1 + 3.2

= 4.2

The single cycle execution time will be:

= Cycle time non-pipeline / Cycle time pipeline

= 1250/350

= 3.5

Partitions are used to divide storage spaces into manageable segments.

Fixed partitions have a predetermined size, and they are used to allocate storage space based on the needs of an application. Fixed partitions are commonly used in mainframe systems, where applications require predictable amounts of storage.

For example, consider an organization that uses a mainframe system to manage its payroll. In this scenario, the organization may use fixed partitions to allocate storage space to the payroll application, ensuring that it has access to a specific amount of storage space at all times.

On the other hand, dynamic partitions allow the operating system to allocate storage space based on the requirements of an application. With dynamic partitions, the size of the partition is not fixed, and it can grow or shrink based on the needs of an application.

For example, consider a personal computer that is used to store and manage different types of data. In this scenario, dynamic partitions are used to allocate storage space to different applications based on their storage requirements.

As new applications are installed, the operating system dynamically allocates storage space to ensure that each application has sufficient storage space to function properly.

Answer: relative references

Explanation:

By default, all cell references are RELATIVE REFERENCES. When copied across multiple cells, they change based on the relative position of rows and columns. For example, if you copy the formula =A1+B1 from row 1 to row 2, the formula will become =A2+B2.

Answer:

angle = float(input('Enter Angle: '))

shadowLength = float5(input('Enter Shadow Length: '))

tree_height = math.tan(angle)*shadowLength

print('Tree Height = {}'.format(tree_height))

Explanation:

From the equation given, the first step is to derive the equation for calculating the Tree Height.

In order to calculate the tangent of an angle, the math module has to be imported. math module allows the program to perform advanced math operations.

The program then prompts the user to input values for angle and shadow length.

The inputted values are converted to floats and used in the equation that was derived for Tree height.

The Establishment Clause of the First Amendment forbids the government from passing any legislation "respecting an establishment of religion."

This section opposes the establishment of an official religion by the government and also forbids government activities that unjustly favor one religion over another. Additionally, it forbids the government from unreasonably favoring either religion or non-religion.

Although some religiously-motivated government activity is acceptable—and perhaps inevitable it is unclear how much the Establishment Clause permits.

The Supreme Court has previously approved the use of public funds for private religious school transportation and textbooks as well as university monies for the printing and dissemination of publications produced by student religious organizations.

Answer:

given us,

principal (p)= Rs 1227

Time(t)= 9

Rate(r)= 6./.

Here,

simple interest= P×T×R/100

= 1227×9×6/100

= 66258/100

= 662.58

Explanation:

by using simple interest formula

The principal investment required to get a total amount, principal plus interest, of Rs 227.00 from simple interest at a rate of 6% per year for 0.75 years (9 months) is $1,174.16

Given Data

Final Amount A = Rs 1227

Time = 9 months

Rate = 6%

Principal = ?

P = A / (1 + rt)

First, converting R percent to r a decimal

r = R/100 = 6%/100 = 0.06 per year.

Putting time into years for simplicity,

9 months / 12 months/year = 0.75 years

Solving our equation:

P = 1227 / ( 1 + (0.06 × 0.75)) = 1174.1626794258

P = $1,174.16
