"My friend here Justin, he's already taken, and he's cracked at Fornite my guy.

I've been contemplating this video a ton of late. I've been considering the video since it gives a provocative message and keen editorial about enslavement and fixation.

To start with, we should take this word by word. The initial segment of the primary sentence; the principal shimmer of gold, is "My companion here Justin" An everyday sentence from the outset, however kindly recollect what I said, to arrive at the pot of gold at the focal point of the cavern of incongruity is justified, despite any trouble. This little portion of the sentence addresses that the storyteller has a companion named Justin. The principal word is possessive; my, and companion here addresses the kid before the camera is indeed Justin, showed by the storyteller naming Justin just after saying companion here. how the storyteller we never see, and even the way that we never see the storyteller entreats us to embed ourselves into them, to place ourselves into their point of view.

"He's now taken" This passage is clear as crystal, aside from one section. "He" shows the subject of the sentence; Justin, is "now" demonstrating that Justin has as of now and is "taken". The virtuoso of this sentence is unpretentious yet significant pleasantry in "taken", as in the old style utilization of this sentence it would imply that Justin is associated with a sentimental or sexual relationship.

"Also, he's cracked at Fortnite" the biggest portion, consequently the one generally stuffed with significance, this selection is the zenith of the multitude of different passages of the sentence. "Also, expands on the last selection demonstrating this is the continuation of the story, and "He's cracked at Fortnite" is the star proclamation of this extract.

"My person". "My person" can allude to numerous things, the storyteller could be alluding to Justin or some obscure outsider. I would excuse the chance of the storyteller alluding to an outsider nonetheless, on the grounds that so far there has been no sign of any outsider in the sum of the video. All things being equal, I think "My person" is alluding to you, the watcher, audience, and peruser. The explanation the storyteller removes time from his day to effectively allude to the eyewitness is on the grounds that the storyteller makes a particular highlight incorporate you, in this manner demonstrating that you are, with regards to the story, in the room noticing Justin.

In general, this show-stopper addresses the narrative of a man's compulsion breaking him while fusing the absolute best incongruity and pleasantry I've ever seen, all done in one video, eight seconds, one sentence, and fourteen words. The incongruity choice and diverting, and the pleasantry smart, this is a provocative piece of media that I would never expect to completely examine, for this remarkable piece of media is worth undeniably more than 200 40,000 words.

Philip runs at an average speed of 4 m/s.
How long will it take Philip to complete a 10 kilometre race? Give your answer in minutes and seconds.

Answers

Answer:

41 minutes 40 seconds

Step-by-step explanation:

10km = 10000m

10000/4 = 2500 seconds

2500/60 = 41.6666...

Hence, 41 minutes 40 seconds.

To solve such type of problems in math's we must know the formula related to motion specifically speed. The time taken for Cameron to complete the race is  2500s

What is time of motion?

When any object cover a particular distance with particular speed then it takes a particular time and this time is called time of motion. The unit of time can be seconds, minutes or hours.

The time of motion is calculated as follows;

time = distance/speed

As distance is given in kilometer so we need to convert kilometer to meter as our speed is in meter per second, so to cancel out the units we must do the conversion and the substituting the values in the above formula

time = 10000/4

time = 2500s

Thus, the time taken for Cameron to complete the race is  2500s when average speed is  4 m/s

Answers

Answer:

a. 76 b. 52

Step-by-step explanation:

The perimeter of a rectangle is the sum of its four sides.

Now all rectangles have a width and a length.

To find the perimeter it is 2 width + 2 length or 2W +2L.

So if the Perimeter P = 344 and Width W = 76 and P = 2W + 2L

Then...

2(76) + 2L = 344 multiply 2 and 76

2L + 152 = 344 subtract 152 from both sides

2L = 192 divide both sides by 2

L = 96

The length is 96.

The equation of an area of a rectangle is A or  area = width x length or W x L

So the equation is A = W x L

If the area is 4732 and the length is 91 then

91W = 4732 divide both sides by 91

W = 52

The width is 52.

a wagon is pulled at speed of 40.0 m/s by a horse exerting 1800 newton horizonal force what is the power of horse

Answers

Answer:

The power of horse is:  P = 72000 W

Step-by-step explanation:

Given

F = 1800 Nv = 40.0 m/s

To determine

P = ?

Using the formula

[tex]\:\:\:P=\overrightarrow{F\cdot }\overrightarrow{v}[/tex]

The  ⋅  in the formula represents a scalar product, defined by:

[tex]\overrightarrow{v\cdot }\overrightarrow{w}=|v||w|cos\:\theta[/tex]

The angle Ф is zero because F and v are are parallel.

Thus the cosine is 1.

Therefore,

P = (1800) (40.0)

P = 72000 W

Hence, the power of horse is:  P = 72000 W

The perimeter of a playing field for a certain sport is 304 ft. The length is 50 ft longer than the width. Find the dimensions.
The width of the playing field is
ft.

Answers

Answer:

Width = 51 ft

Step-by-step explanation:

Use the perimeter formula and add on additional information. Use a variable to form the equation.

P = 2L + 2W

304 = 2(x+50) + 2(x)

Then, simplify the expression.

304 = 2x + 100 + 2x

304 = 4x + 100

204 = 4x

51 = x

This means that the length is 101 ft and the width is 51 ft.

Answer:

P = 2 l + 2 w

304 ft = 2 x 50 ft + 2 w

= 100 ft + 2w

2w = 204 ft

w = 102 ft

ANSWER: width is 102 ft

A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 92.4% for the medical students admitted through special programs.

Required:
a. If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated.
b. If 12 of the students from the special programs are randomly selected, find the probability that exactly 9 of them graduated.
c. Would it be unusual to randomly select 12 students from the special programs and get exactly 9 that graduate?

Answers

Answer:

a) 0.7696 = 76.96% probability that at least 11 of them graduated.

b) 0.0474 = 4.74% probability that exactly 9 of them graduated.

c) Since 9 is less than 2.5 standard deviations from the mean, it would not be unusual.

Step-by-step explanation:

For each student, there are only two possible outcomes. Either they graduated, or they did not. Each student is independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Unusual outcome:

An outcome in the binomial distribution is unusual if it is more than 2.5 standard deviations from the mean.

92.4% for the medical students admitted through special programs.

This means that [tex]p = 0.924[/tex]

a. If 12 of the students from the special programs are randomly selected, find the probability that at least 11 of them graduated.

This is [tex]P(X \geq 11)[/tex] when [tex]n = 12[/tex]. So

[tex]P(X \geq 11) = P(X = 11) + P(X = 12)[/tex]

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 11) = C_{12,11}.(0.924)^{11}.(0.076)^{1} = 0.3823[/tex]

[tex]P(X = 12) = C_{12,12}.(0.924)^{12}.(0.076)^{0} = 0.3873[/tex]

[tex]P(X \geq 11) = P(X = 11) + P(X = 12) = 0.3823 + 0.3873 = 0.7696[/tex]

0.7696 = 76.96% probability that at least 11 of them graduated.

b. If 12 of the students from the special programs are randomly selected, find the probability that exactly 9 of them graduated.

This is P(X = 9). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 9) = C_{12,9}.(0.924)^{9}.(0.076)^{3} = 0.0474[/tex]

0.0474 = 4.74% probability that exactly 9 of them graduated.

c. Would it be unusual to randomly select 12 students from the special programs and get exactly 9 that graduate?

The mean number of students expected to graduate is:

[tex]E(X) = np = 12*0.924 = 11.09[/tex]

The standard deviation is

[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{12*0.924*0.076} = 0.92[/tex]

11.09 - 2.5*0.92 = 8.79

This means that anything below 8.79 is unusual, so, since 9 is less than 2.5 standard deviations from the mean, it would not be unusual.

Answers

Answer:

The distance of each of Marta's first four jumps is of 15.5 feet.

Step-by-step explanation:

Average:

The average of a data set is given by the sum of all elements of the data set divided by the number of elements in the data set.

Marta's jumps:

First four of j.

Lax six are 1 1/2 feet longer = 1.5 feet longer, so j + 1.5.

Six jumps, average of 16.

What is the distance of each of Marta's first four jumps?

This is j. So

[tex]\frac{4j + 2(j + 1.5)}{6} = 16[/tex]

[tex]4j + 2j + 3 = 96[/tex]

[tex]6j = 93[/tex]

[tex]j = \frac{93}{6}[/tex]

[tex]j = 15.5[/tex]

The distance of each of Marta's first four jumps is of 15.5 feet.
