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.

Answer:

  31

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:

Step-by-step explanation:

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

Answer:   10.911

Step-by-step explanation:

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)

Answer:

n-k-1

Step-by-step explanation:

n is bigger than k. It asks BETWEEN k and n. so, since n is bigger than k, n-k. since it says BETWEEN, you subtract 1 after that

got it?

=)

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.

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
