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

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

Answers

Step-by-step explanation:

The relationship between sides and the sum of angles is ...

  sum of angles = (sides - 2)·180°

Filling in the given value and solving for "sides", we get ...

  5220 = (sides -2)180

  29 = sides -2 . . . . . . . . . divide by 180

  31 = sides . . . . . . . . . . . . add 2

The polygon has 31 sides.

Answer:

Answers

Answer:

See below

Step-by-step explanation:

Note: missing graph is attached

Solution

A) The two points are:

(4, 19) and (7, 7)

B) Slope formula: m = (y2-y1)/(x2-x1)

m = (7 - 19)/(7-4)m = -12/3m = -4

C) Point-slope formula:

y - y1 = m(x - x1)

Using one of the points we get:

y - 19 = -4(x - 4)

D) Delivery time on Day 0:

y - 19 = -4(0 - 4)y - 19 = 16y = 16 + 19y = 35 minutes

Delivery time decreases by the value of the slope which is 4 minutes per day

oh and the reason i am strict about BETWEEN, is because when it said between, then its discluding k and n.

If it says FROM k and n, then you both include k and n, and that would result of adding 1 instead of subtracting 1.

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)

When the author visited Dublin, Ireland (home of Guinness Brewery employee William Gosset, who first developed the t distribution), he recorded the ages of randomly selected passenger cars and randomly selected taxis. The ages can be found from the license plates. (There is no end to the fun of traveling with the author.) The ages (in years) are listed below. We might expect that taxis would be newer, so test the claim that the mean age of cars is greater than the mean age of taxis. Use α= 0.05 significance level to test the claim that in Dublin, car ages and taxi ages have the same variation.

Car Ages 4 0 8 11 14 3 4 4 3 5 8 3 3 7 4 6 6 1 8 2 15 11 4 1 6 1 8

Answers

Answer:

The  Decision Rule

Fail to reject the null hypothesis

The conclusion

 There is no sufficient evidence to support the claim that the mean age of the cars is greater than that of taxi

Step-by-step explanation:

From the question we are told that

   The data is  

      Car Ages 4 0 8 11 14 3 4 4 3 5 8 3 3 7 4 6 6 1 8 2 15 11 4 1 6 1 8

     Taxi Ages 8 8 0 3 8 4 3 3 6 11 7 7 6 9 5 10 8 4 3 4

      The  level of significance [tex]\alpha = 0.05[/tex]

 Generally the null hypothesis  is  [tex]H_o  :  \mu_1 - \mu_2  = 0[/tex]

                  the alternative hypothesis is   [tex]H_a  :  \mu_1 - \mu_2 >  0[/tex]

Generally the sample mean for the age of  cars is mathematically represented as

        [tex]\= x_1 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x_1 = \frac{4+ 0+ 8 +11 + \cdots + 8 }{27}[/tex]

=>     [tex]\= x_1 = 5.56[/tex]

Generally the standard deviation of age of  cars

     [tex]\sigma _1  = \sqrt{\frac{\sum (x_i - \= x)^2}{n_1} }[/tex]

=>  [tex]\sigma _1  = \sqrt{\frac{(4 - 5.56)^2 + (0 - 5.56)^2+ (8 - 5.56)^2 + \cdots + 8}{ 27} }[/tex]

=>  [tex]\sigma _1  =  3.88 [/tex]

Generally the sample mean for the age of taxi is mathematically represented as

        [tex]\= x_2 = \frac{\sum x_i }{n}[/tex]

=>     [tex]\= x_2 = \frac{8 +8 +0  + \cdots + 4 }{20}[/tex]

=>     [tex]\= x_2 = 5.85 [/tex]

Generally the standard deviation of age of  taxi

[tex]\sigma _2  = \sqrt{\frac{\sum (x_i - \= x)^2}{n_1} }[/tex]

=>  [tex]\sigma _2  = \sqrt{\frac{(8 - 5.85)^2 + (8 - 5.85)^2+ (0 - 5.85)^2 + \cdots + 8}{ 20} }[/tex]

=>  [tex]\sigma _2  = 2.83 [/tex]

Generally the test statistics is mathematically represented as

   [tex]t = \frac{(\= x_ 1 - \= x_2 ) - 0}{\sqrt{\frac{\sigma^2_1}{n_1}  + \frac{\sigma^2_2}{n_2} }  }[/tex]

=> [tex]t = \frac{(5.56 - 5.85 ) - 0}{\sqrt{\frac{(3.88)^2}{27}  + \frac{(2.83)}{20} }}[/tex]  

=> [tex]t = -0.30 [/tex]  

Generally the degree of freedom is mathematically  represented as

   [tex]df =  n_1 + n_2 -2[/tex]

    [tex]df =  27 +  20 -2[/tex]

    [tex]df =  45[/tex]

From the t distribution table  the [tex]P(t >  t )[/tex] at the obtained degree of freedom = 45 is  

   [tex]P(t >  -0.30 ) = 0.61722067[/tex]

So  the  p-value  is

    [tex]p-value  =  P(t >  T) =  0.61722067[/tex]

From the obtained values we see that the  p-value  >  [tex]\alpha [/tex] hence we fail to reject the null hypothesis

Hence the there is no sufficient evidence to support the claim that the mean age of the cars is greater than that of taxi
