Please find attached to this answer, a hand drawn diagram

Answer:

12.84°

Explanation:

To calculate Angle of Depression, we calculate using Trigonometric function or ratio. The Trigonometric function or ratio to be used based on the diagram is  Sine

sin θ = Opposite side/Hypotenuse

θ = Angle of Depression

Opposite side = Height  = 200 feet

Adjacent side = Distance of the flying bird to the observer = 900 feet

sin θ = 200feet/ 900 feet

θ = sin-¹ (2/9) or arcsin(2/9)

θ = 12.839588407°

Approximately = 12.84°

Therefore, Angle of Depression = 12.84°

____ [38]

This question is missing the excerpt. I've found the complete question online. It is as follows:

Read the excerpt from "The Storyteller."

"Why weren't there any flowers?"

"Because the pigs had eaten them all," said the bachelor promptly. "The gardeners had told the Prince that you couldn't have pigs and flowers, so he decided to have pigs and no flowers."

There was a murmur of approval at the excellence of the Prince's decision; so many people would have decided the other way.

How does the characterization of the children create satire?

Answer:

The characterization of the children create satire because:

B. They are pleased to learn that the prince chooses pigs over flowers.

Explanation:

A satire exposes the difference between our beliefs and reality. In the short story "The Story-Teller", by Saki, the satire comes from the situational irony presented in the bachelor's story. The bachelor is traveling in a train wagon with three children and their aunt. The aunt tells them a story with the purpose of teaching them a moral lesson. To her disappointment, the children find the story boring.

The bachelor begins to tell a story himself. Unlike the predictable story told by the aunt, his story is filled with surprises and ironic incidents. Instead of teaching kids that they should be good, he teaches them that being too good may be an awful thing. <u>The children's characterization in the excerpt creates satire because they are pleased to learn the prince in the story chose to have pigs instead of flowers. Their reaction contradicts what society would expect of them. It goes against what the aunt - a representative of society - thinks is appropriate. They are not pleased by what is right or good - they are pleased by what is entertaining.</u>

Read this sentence from the passage.
Alex_Xolod [135]

Answer:

Hello. You did not enter the answer options, but the term "previously perused paperbacks" is an euphemism for the term "softcover books" or "flimsy books".

Explanation:

Euphemism is a figure of speech that is used to relieve a term, that is, euphemism allows the author to use a term that softens the sentence and has a milder and more pleasant meaning, to replace another term, which is more aggressive , can cause pelomic and discomfort to the reader.

In this case, we can say that the author uses the term "previously perused paperbacks" as an euphemism when referring to books with a soft, soft and rigid cover.

A survey of 80 students found that 24 students both play in the band and play a sport. But 22 students are not in band and do no
Rzqust [24]

Answer:

<u><em></em></u>

  • <u><em>D) Column: In a Band, Not in a Band; Row: Play a Sport, Do Not Play a Sport</em></u>

<u><em></em></u>

Explanation:

The answer choices are:

  • A) Column: In a Band, Play a Sport; Row: Not in a Band, Do Not Play a Sport
  • B) Column: Not in a Band, Play a Sport; Row: In a Band, Do Not Play a Sport
  • C) Column: In a Band, Do Not Play a Sport; Row: Not in a Band, Play a Sport
  • D) Column: In a Band, Not in a Band; Row: Play a Sport, Do Not Play a Sport

<h2>Solution</h2>

You should build a two-way frequency table with:

  • Play in the band, and not play in the band
  • Play a sport, and do not play a sport.

It is not important if playing/not playing in the band are in columns or in rows; the important thing is they both must below either to different columns or to different rows. The same is valid for playing a sport.

Then, these two forms are good for the two-way frequency table:

Option 1:

                                 Play in the band   Do not play in the band  Total

Play sport

Do not play sport

Total

Option 2:

                                             Play sport    Do not play sport    Total

Play in the band

Do not play in the band

Total

As for the options:

  • A) Column: In a Band, Play a Sport; Row: Not in a Band, Do Not Play a Sport

        This is placing In a band and Play a sport in different columns, when they should be in different rows,

       

  • B) Column: Not in a Band, Play a Sport; Row: In a Band, Do Not Play a Sport

       This is placing not in a band and Play a Sport in different columns when they should be in different rows.

  • C) Column: In a Band, Do Not Play a Sport; Row: Not in a Band, Play a Sport

         This is placing In a band and Do not play a Sport in different columns when they should be in different rows.

  • D) Column: In a Band, Not in a Band; Row: Play a Sport, Do Not Play a Sport

        This correctly describes the survey: it corresponds to the option #1 above.
