The are two schools of ____________ are Symmetry and Asymmetry.

Answers

The two schools of design that encompass symmetry and asymmetry are known as symmetrical design and asymmetrical design.

Symmetrical design is characterized by the balanced distribution of visual elements on either side of a central axis. It follows a mirror-like reflection, where the elements on one side are replicated on the other side, creating a sense of equilibrium and harmony.

Symmetrical designs often evoke a sense of formality, stability, and order.

On the other hand, asymmetrical design embraces a more dynamic and informal approach. It involves the intentional placement of visual elements in an unbalanced manner, without strict adherence to a central axis.

Asymmetrical designs strive for a sense of visual interest and tension through the careful juxtaposition of elements with varying sizes, shapes, colors, and textures.

They create a more energetic and vibrant visual experience.

Both symmetrical and asymmetrical design approaches have their merits and are employed in various contexts. Symmetry is often used in formal settings, such as architecture, classical art, and traditional graphic design, to convey a sense of elegance and tradition.

Asymmetry, on the other hand, is commonly found in contemporary design, modern art, and advertising, where it adds a sense of dynamism and creativity.

In conclusion, the schools of symmetry and asymmetry represent distinct design approaches, with symmetrical design emphasizing balance and order, while asymmetrical design embraces a more dynamic and unbalanced aesthetic.

Explanation:

Stacy, Inc., produces a product using a process that allows for substitution between two materials, Alpha and Beta. The company has the following direct materials data for its product.


Standard costs for one unit of output
Alpha 48 units of input at $ 9.00
Beta 96 units of input at $ 11.50


The company had the following results in June.

Units of output produced 2,400 units
Materials purchased and used
Alpha 123,200 units at $ 8.70
Beta 222,400 units at $ 12.00


Required:

a. Compute materials price and efficiency variances.

b. Compute materials mix and yield variances.

Answers

Explanation:

a. Materials price variance:

Alpha:

Actual quantity purchased and used = 123,200 units

Actual cost = $ 8.70 per unit

Standard cost = $ 9.00 per unit

Price variance = (Actual price - Standard price) x Actual quantity

Price variance = ($ 8.70 - $ 9.00) x 123,200 units

Price variance = -$ 3,696 (Favorable)

Beta:

Actual quantity purchased and used = 222,400 units

Actual cost = $ 12.00 per unit

Standard cost = $ 11.50 per unit

Price variance = (Actual price - Standard price) x Actual quantity

Price variance = ($ 12.00 - $ 11.50) x 222,400 units

Price variance = $ 11,100 (Unfavorable)

Materials efficiency variance:

Alpha:

Actual quantity used = 2,400 units x 48 units per unit of output = 115,200 units

Standard quantity allowed = 2,400 units x 48 units per unit of output = 115,200 units

Efficiency variance = (Standard quantity - Actual quantity) x Standard price

Efficiency variance = (115,200 - 123,200) x $ 9.00

Efficiency variance = -$ 72,000 (Unfavorable)

Beta:

Actual quantity used = 2,400 units x 96 units per unit of output = 230,400 units

Standard quantity allowed = 2,400 units x 96 units per unit of output = 230,400 units

Efficiency variance = (Standard quantity - Actual quantity) x Standard price

Efficiency variance = (230,400 - 222,400) x $ 11.50

Efficiency variance = $ 92,160 (Favorable)

b. Materials mix variance:

Standard mix:

Alpha: 48 / (48 + 96) = 33.33%

Beta: 96 / (48 + 96) = 66.67%

Actual mix:

Alpha: 123,200 / (123,200 + 222,400) = 35.60%

Beta: 222,400 / (123,200 + 222,400) = 64.40%

Mix variance = (Actual mix - Standard mix) x Actual quantity x Standard price

Mix variance = (0.0356 - 0.3333) x 2,400 units x $ 9.00

Mix variance = -$ 14,246 (Favorable)

Materials yield variance:

Standard yield:

Alpha: 2,400 units

Beta: 2,400 units

Actual yield:

Alpha: 123,200 / 48 = 2,566.67 units

Beta: 222,400 / 96 = 2,316.67 units

Yield variance = (Standard quantity - Actual quantity) x Standard price

Yield variance = (2,400 - 2,316.67) x $ 9.00

Yield variance = $ 751.20 (Unfavorable)

from the following tcp communication flags identity the flag which initiates a connection between different hosts.

Answers

From the given TCP communication flags, the flag which initiates a connection between different hosts is the SYN flag.

What is SYN flag?

The SYN flag is a control flag used in the Transmission Control Protocol (TCP) to initiate a connection between two computers. When the SYN flag is set, the first computer sends a SYN packet to the second computer, which responds with an acknowledgment (ACK) packet.

This exchange of SYN and ACK packets between two computers is known as the TCP three-way handshake. After this three-way handshake is completed, a connection is established and the two computers can begin sending data back and forth. The SYN flag is used for other purposes as well, such as for retransmission of lost packets and to close a TCP connection.

You work for an exchange bank. At the end of the day a teller needs to be able to add up the value of all of the foreign currency they have. A typical interaction with the computer program should look like this:

How many Euros do you have?
245.59

How many Mexican Pesos do you have?
4678

How many Chinese Yen do you have?
5432

The total value in US dollars is: $1378.73

Think about how to break this problem into simple steps. You need to ask how much the teller has of each currency, then make the conversion to US dollars and finally add the dollar amounts into a total.
Here is a sketch of the solution.

double currencyAmount;
double total;

// get the amount for the first currency
total += currencyAmount;

// get the amount for the second currency
total += currencyAmount;

// get the amount for the third currency
total += currencyAmount;

// output the total
Notice the use of the += operator, this is a shortcut that means the same thing as total = total + currencyAmount. It is usful for accumulating a total like we are doing here.
Submit only the .cpp file containing the code. Don't forget the code requirements for this class:
Good style: Use good naming conventions, for example use lower camel case variable names.
Usability: Always prompt the user for input so they know what to do and provide meaningful output messages.
Documentation: Add a comments that document what each part of your code does.
Testing: Don't submit your solution until you have tested it. The code must compile, execute and produce the correct output for any input.

- What is the largest number of nodes that T can have? _____________________
- What is the smallest number of nodes that T can have? ____________________

ii. The worst case complexity of deleting any arbitrary node element from heap is ___________

Answers

Answer:

i. A min heap of height 3 will have a root node with two children, each of which has two children of its own, resulting in a total of 7 nodes at the bottom level. Therefore:

The largest number of nodes that T can have is 1 + 2 + 4 + 7 = 14.

The smallest number of nodes that T can have is 1 + 2 + 4 = 7.

ii. The worst case complexity of deleting any arbitrary node element from a heap is O(log n), where n is the number of nodes in the heap. This is because deleting a node from a heap requires maintaining the heap property, which involves swapping the deleted node with its child nodes in order to ensure that the heap remains complete and that the heap property is satisfied. This process requires traversing the height of the tree, which has a worst-case complexity of O(log n).
