When the slope is undefined, we have a vertical line

A vertical line is of the form

x=

We have a point ( -4,2) so the x coordinate is -4

eight water faucets having the same rate of flow,fill a tank in 27 minutes.If two faucets are turned off,how long will the remaining 6water faucets take to fill the tank?​

Answers

Answer:

36 minutes

Step-by-step explanation:

If x is the flow rate of each faucet, then 8x is the flow of eight faucets, and the volume of the tank is:

V = (8x) (27)

V = 216x

When there are six faucets, the time is:

216x = (6x) t

t = 36

Restless Leg Syndrome and Fibromyalgia
People with restless leg syndrome have a strong urge to move their legs to stop uncomfortable sensations. People with fibromyalgia suffer pain and tenderness in joints throughout the body. A recent study indicates that people with fibromyalgia are much more likely to have restless leg syndrome than people without the disease. The study indicates that, for people with fibromyalgia, the probability is 0.33 of having restless leg syndrome, while for people without fibromyalgia, the probability is 0.03. About 2% of the population has fibromyalgia. Create a tree diagram from this information and use it to find the probability that a person with restless leg syndrome has fibromyalgia.

Answers

Answer:

The probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

Step-by-step explanation:

Denote the events as follows:

F = a person with fibromyalgia

R = a person having restless leg syndrome

The information provided is as follows:

P (R | F) = 0.33

P (R | F') = 0.03

P (F) = 0.02

Consider the tree diagram attached below.

Compute the probability that a person with restless leg syndrome has fibromyalgia as follows:

[tex]P(F|R)=\frac{P(R|F)P(F)}{P(R|F)P(F)+P(R|F')P(F')}\\\\=\frac{(0.33\times 0.02)}{(0.33\times 0.02)+(0.03\times 0.98)}\\\\=0.183333\\\\\approx 0.1833[/tex]

Thus, the probability that a person with restless leg syndrome has fibromyalgia is 0.1833.

The equation Ax + By = 14 goes through the coordinates (-7, -4) and (14, 2).
What are the values of A and B?

Answers

Answer:

A=-6

B=7

Step-by-step explanation:

We want to solve for the values of A and B.

let us substitute the values of the coordinates, that is x and y into the expression and obtain the two equations.

then we solve simultaneously

-7A-4B=14---------1

14A+2B=14--------2

-14A+-8B=28---------3

14A+2B=14------------2

0-6B=42

6B=42

B=42/6

B=7

put B=7 in eqn 1 we have

-7A-4(7)=14---------1

-7A-28=14

-7A=14+28

-7A=42

A=42/-7

A=-6

The values of A and B are 3 and -7 respectively

In order to determine the values of A and B,

First, we will determine the equation of the line passing through the coordinates (-7, -4) and (14, 2).

Using the formula for determining the equation of a line with two given points,

[tex]\frac{y-y_{1} }{x -x_{1} } =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

From the question

x₁ = -7

y₁ = -4

x₂ = 14

y₂ = 2

Putting these values into the equation,

We get

[tex]\frac{y--4}{x--7} =\frac{2--4}{14--7}[/tex]

∴ [tex]\frac{y+4}{x+7} =\frac{2+4}{14+7}[/tex]

[tex]\frac{y+4}{x+7} =\frac{6}{21}[/tex]

This becomes,

[tex]6(x+7) = 21(y+4)[/tex]

Clearing the brackets

[tex]6x + 42 = 21y + 84[/tex]

Then,

[tex]6x -21y = 84 -42[/tex]

[tex]6x -21y = 42[/tex]

Dividing through by 3

We get

[tex]3x - 7y = 14[/tex]

∴ The equation of the line that goes through the coordinates (-7, -4) and (14, 2) is [tex]3x - 7y = 14[/tex]

Now, we will compare the above equation to the equation given.

The given equation is Ax + By = 14

By comparing

A = 3 and B = -7

Hence, the values of A and B are 3 and -7 respectively

Answers

Answer:

X intercept: x = 4 or in point form (4,0)

Zero for the function at (4, 0)

Y intercept : y = 160  or in point form (0,160)

slope = -40  mph

Step-by-step explanation:

The y-intercept, x-intercept are directly obtained from the graph by noticing the points on the axes where the line crosses them.

The slope is calculated using the points (0, 160) and (4, 0) and the formula for the slope of the segment that joins them:

slope = (y2 - y1)/(x2 - x1) = (160 - 0) / (0 - 4) = -160/4 = -40

and the units of the slope are miles over hour (that is miles per hour or mph)

The Walt Disney Company, the production studio behind the Marvel Cinematic Universe, is trying to find the best release date for their new super hero movie. They are hesitating between the summer and winter holiday release, and they want to know if there is any difference between the earning potential during those seasons. The analytics division in the company examined a random sample of box-office data for movies released during the past 5 years in the USA and Canada and found that 52 out of 1258 movies with summer release date earned over 400 million dollars. They also counted that out of 545 movies released in the winter, 8 earned over 400 million dollars.
Over 4 million USD Under 4 million USD
Summer release 57 1251
Winter release 11 544
Total
1. We want to investigate whether there is a difference in the proportion of movies that eam over 400 million dollars for the two release seasons. Which hypotheses should we use?
2. Calculate the difference in the proportions of movies that eamed over 400 million dollars.
3. The paragraph below describes the set up for a randomization test, if we were to conduct a hypothesis test without using software. Fill in the blanks with a number.
We write Summer on_____cards and cards representing the movies with summer release date, and Winter on_____cards. Then, we shuffle these cards and split them into two groups one group of size_____representing the movies with box-office over 400 million dollars, and another group of size_____representing the rest of the movies. We calculate the difference in the proportions of movies that eaned over 400 million dollars during the two release seasons to get PSmmer PWinter. Finally, we build a histogram of these simulated dfterences.

Answers

Answer:

Step-by-step explanation:

                           Over 4 million USD    Under 4 million USD    Total

Summer release      57                               1195                         1251

Winter release         11                                533                           544

1)Let [tex]P_1[/tex] be the proportion of movies that earn over 400 million in summer and [tex]P_2[/tex] be the proportion of movies that earn over 400 million in winter.

Null hypothesis:[tex]H_0:P_1= P_2[/tex]

Alternate hypothesis : [tex]H_a: P_1 \neq P_2[/tex]

2)Calculate the difference in the proportions of movies that earned over 400 million dollars.

[tex]P_1=\frac{57}{1251}=0.045[/tex]

[tex]P_2=\frac{11}{544}=0.0202[/tex]

3)

[tex]P_{(Summer)}-P_{(winter)}=0.045-0.0202=0.0248[/tex]

We write Summer on 1251 cards and cards representing the movies with summer release date, and Winter on 544 cards. Then, we shuffle these cards and split them into two groups one group of size 68 representing the movies with box-office over 400 million dollars, and another group of size representing 1728 the rest of the movies.

What are trigonometric ratios?

The trigonometric ratios are defined for a right angled triangle.

The example of these ratios are sin, cos, tan, cosec, sec and cot.

The trigonometric ratios are useful in determining the heights and distances of the large objects.

The graph for the given question shows that for the given function the range and domain are as follows,

Domain =  [-1, 1]

Range = [0, π]

The value of the function at 0 is π/2.

Since only the inverse of sinusoids have their range as [-1, 1] and the value of cos(x) at x = π/2 is 0. It implies that the given function is inverse of cos(x).

Hence, the given function represents inverse function of cos(x) which is cos^-1(x).
