which table shows a proportional relationship between x and y ?
Answers
Answer:
Table C
Step-by-step explanation:
Given
Table A to D
Required
Which shows a proportional relationship
To do this, we make use of:
[tex]k = \frac{y}{x}[/tex]
Where k is the constant of proportionality.
In table (A)
x = 2, y = 4
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{4}{2}[/tex]
[tex]k = 2[/tex]
x = 4, y = 9
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{9}{4}[/tex]
[tex]k = 2.25[/tex]
Both values of k are different. Hence, no proportional relationship
In table (B)
x = 3, y = 4
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{4}{3}[/tex]
[tex]k = 1.33[/tex]
x = 9, y = 16
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{16}{9}[/tex]
[tex]k = 1.78[/tex]
Both values of k are different. Hence, no proportional relationship
In table (C):
x = 4, y = 12
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{12}{4}[/tex]
[tex]k = 3[/tex]
x = 5, y = 15
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{15}{5}[/tex]
[tex]k = 3[/tex]
x = 6, y = 18
[tex]k = \frac{y}{x}[/tex]
[tex]k = \frac{18}{6}[/tex]
[tex]k = 3[/tex]
This shows a proportional relationship because all values of k are the same for this table

For the given functions f and g, find the indicated composition.
f(x) = -6x +5, g(x) = 2x + 8; (g of)(x)
A. - 12x - 2
В.- 12x + 53
C. 12x + 18
D.- 12x + 18
Answers
Answer:
D. -12x + 18
Step-by-step explanation:
f(x) = -6x +5; g(x) = 2x + 8
[g o f](x) = g(f(x))
this means that in g(x), everywhere there's an x, f(x) replaces it. [g o f](x) is represented at the following: (f(x) is in bold)
g(f(x)) = 2(-6x +5) + 8 distribute the 2 to (-6x + 5)
g(f(x)) = -12x + 10 + 8 combine like terms
g(f(x)) = -12x + 18

8 is not in the solution set
Step-by-step explanation:
Given, -y + 7 < -4
To find out if 8 is in the solution set, substitute y = 8 in the inequality and solve to see if the statement would be true.
Thus:
-8 + 7 < -4
-1 < -4
This -1 is less than -4. This is actually not TRUE. -1 is rather greater than -4.
Therefore, 8 is not in the solution set.

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.) He decides to give all male athletes Gatorade and the female athletes eitherPowerade or Vitaminwater.
D.) He has some of the athletes drink the sports drink two hours beforerunning,others one hour before running, and the rest 30 minutes beforerunning.
Step-by-step explanation:
Confounding variables could be described as variables which introduces elements that causes unwanted relationship between measured variables in data. Such that observed relationship is actually not as a result of the independent variable.
The confounding variables in the options chosen are gender and timing of the consumption and when the athletes eventually ran.
As for gender, male athletes are expected to put up a better running speed and energy than women and Hence would finish the rate faster based on these fact. Hence, it will be wrong to conclude that Gatorade has Better effect on performance.
As for timing, those who run shortly after taking an energy drink are more likely to be boosted that those who take much later and this the effect may not necessarily be in the type of energy drink consumed.
Confounding variables are the variables which are not related to the experiment.
Gender would be confounded with sports drink since we cannot distinguish their effects from each other.Sports drink would be confounded with timing of the drink, since we could not distinguish their effects from each other.What is confounding variable?Confounding variables are the variables which are not related to the experiment. Confounding variables provides the affects the useless results and affects the experiment.
Given information-
The total number of meters the athletes runs is 400 meters.
The sports drink given to athletes are Powerade, Gatorade and Vitamin water.
The given options are,
a) He decides to give all male athletes Gatorade and the female athletes either Powerade or Vitaminwater- As the male atheletes likely have more power and energy to run than the female athletes. Thus this can ruin the experiment. b) Yes gender would be confounded with sports drink since we cannot distinguish their effects from each other.c) He allows each athlete to choose their favorite drink from a cooler- To choose favorite drink does not affect the experiment.d. He has some of the athletes drink the sports drink two hours before running, others one hour before running, and the rest 30 minutes before running- The athletes who have taken drink just before the race, have more energy. Thus it is a confounding variable.e. He has some of the athletes drink Gatorade two hours before running, others drink Powerade one hour before running, and the rest Vitamin water half an hour before running-similar effect as the in the above case with the timing for this option.f). Yes sports drink would be confounded with timing of the drink, since we could not distinguish their effects from each other.Hence,

"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.

What is the distance of each of Marta's first four jumps? show work plz.
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.

A. 1 B.2 C.3 D.4
Answers
Answer:
I believe the answer is c) 3
Step-by-step explanation:
f(x) = (x + 3)(x - 1)(2x + 2)
x(x) + x(-1) + 3(x) + 3(-1)
f(x) = (x^2 - x + 3x - 3)(2x + 2)
f(x) = (x^2 + 2x - 3)(2x + 2)
2x(x^2) + 2x(2x) + 2x(-3) + 2(x^2) + 2(2x) + 2(-3)
f(x) = (2x^3 + 4x^2 - 6x + 2x^2 - 6)
f(x) = (2x^3 + 6x^2 - 6x - 6)
Suppose there are 4 defective batteries in a drawer with 10 batteries in it. A sample of 3 is taken at random without replacement. Let X denote the number of defective batteries in the sample. Find the probability that the sample contains a) Exactly one defective battery b) at most one defective battery. c) at least one defective battery.
Answers
Answer:
a.) 0.5
b.) 0.66
c.) 0.83
Step-by-step explanation:
As given,
Total Number of Batteries in the drawer = 10
Total Number of defective Batteries in the drawer = 4
⇒Total Number of non - defective Batteries in the drawer = 10 - 4 = 6
Now,
As, a sample of 3 is taken at random without replacement.
a.)
Getting exactly one defective battery means -
1 - from defective battery
2 - from non-defective battery
So,
Getting exactly 1 defective battery = ⁴C₁ × ⁶C₂ = [tex]\frac{4!}{1! (4 - 1 )!}[/tex] × [tex]\frac{6!}{2! (6 - 2 )!}[/tex]
= [tex]\frac{4!}{(3)!}[/tex] × [tex]\frac{6!}{2! (4)!}[/tex]
= [tex]\frac{4.3!}{(3)!}[/tex] × [tex]\frac{6.5.4!}{2! (4)!}[/tex]
= [tex]4[/tex] × [tex]\frac{6.5}{2.1! }[/tex]
= [tex]4[/tex] × [tex]15[/tex] = 60
Total Number of possibility = ¹⁰C₃ = [tex]\frac{10!}{3! (10-3)!}[/tex]
= [tex]\frac{10!}{3! (7)!}[/tex]
= [tex]\frac{10.9.8.7!}{3! (7)!}[/tex]
= [tex]\frac{10.9.8}{3.2.1!}[/tex]
= 120
So, probability = [tex]\frac{60}{120} = \frac{1}{2} = 0.5[/tex]
b.)
at most one defective battery :
⇒either the defective battery is 1 or 0
If the defective battery is 1 , then 2 non defective
Possibility = ⁴C₁ × ⁶C₂ = 60
If the defective battery is 0 , then 3 non defective
Possibility = ⁴C₀ × ⁶C₃
= [tex]\frac{4!}{0! (4 - 0)!}[/tex] × [tex]\frac{6!}{3! (6 - 3)!}[/tex]
= [tex]\frac{4!}{(4)!}[/tex] × [tex]\frac{6!}{3! (3)!}[/tex]
= 1 × [tex]\frac{6.5.4.3!}{3.2.1! (3)!}[/tex]
= 1× [tex]\frac{6.5.4}{3.2.1! }[/tex]
= 1 × 20 = 20
getting at most 1 defective battery = 60 + 20 = 80
Probability = [tex]\frac{80}{120} = \frac{8}{12} = 0.66[/tex]
c.)
at least one defective battery :
⇒either the defective battery is 1 or 2 or 3
If the defective battery is 1 , then 2 non defective
Possibility = ⁴C₁ × ⁶C₂ = 60
If the defective battery is 2 , then 1 non defective
Possibility = ⁴C₂ × ⁶C₁
= [tex]\frac{4!}{2! (4 - 2)!}[/tex] × [tex]\frac{6!}{1! (6 - 1)!}[/tex]
= [tex]\frac{4!}{2! (2)!}[/tex] × [tex]\frac{6!}{1! (5)!}[/tex]
= [tex]\frac{4.3.2!}{2! (2)!}[/tex] × [tex]\frac{6.5!}{1! (5)!}[/tex]
= [tex]\frac{4.3}{2.1!}[/tex] × [tex]\frac{6}{1}[/tex]
= 6 × 6 = 36
If the defective battery is 3 , then 0 non defective
Possibility = ⁴C₃ × ⁶C₀
= [tex]\frac{4!}{3! (4 - 3)!}[/tex] × [tex]\frac{6!}{0! (6 - 0)!}[/tex]
= [tex]\frac{4!}{3! (1)!}[/tex] × [tex]\frac{6!}{(6)!}[/tex]
= [tex]\frac{4.3!}{3!}[/tex] × 1
= 4×1 = 4
getting at most 1 defective battery = 60 + 36 + 4 = 100
Probability = [tex]\frac{100}{120} = \frac{10}{12} = 0.83[/tex]
