Answer:

a

[tex]P(G = 2 ,  Y= 1 , R = 2) = 0.13184 [/tex]

b

[tex]P(G = R ) =  0.13919  [/tex]

Step-by-step explanation:

From the question we are told that

   The probability of the traffic light being green is [tex]p_g = \frac{3}{8}[/tex]

   The probability of the traffic light being red is  [tex]p_r = \frac{1}{2}[/tex]

   The probability of the traffic light being yellow is  [tex]p_y = \frac{1}{8}[/tex]

   The number of days of observation is n = 5

Generally the probability distribution function for a multinomial distribution is mathematically represented as

          [tex]Pr( X_1 = x_1 \ and \ . . .  \ and  \  X_k =x_k) =  \left \{ {{ \frac{n!}{x_1 ! , . . . x_k !} p_1^{x_1} * \cdots *p_k^{x_k} \ \ \ \ \ \ \  when \  \sum x_i = n } \atop {0 }\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  \ \ \ \ \    otherwise  \ } \right[/tex]

Generally the probability that P[G=2, Y=1, R=2]

     [tex]P(G = 2 ,  Y= 1 , R = 2) = \frac{5!}{ 2! * 1! * 2!} *  [\frac{3}{8} ]^2 * [\frac{1}{8} ]^1 * [\frac{1}{2} ] ^2[/tex]

=> [tex]P(G = 2 ,  Y= 1 , R = 2) = 0.13184 [/tex]

Generally the probability that P[G=R] is mathematically represented as

          [tex]P(G = R ) =  P( G =  2 ,  Y = 1 ,  R = 2) + P( G =  0 ,  Y = 5 ,  R = 0)+ P( G =  1 ,  Y = 3 ,  R = 1)[/tex]

Here

    [tex] P( G =  0 ,  Y = 5 ,  R = 0) =  \frac{5!}{ 0! * 5! * 0!} *  [\frac{3}{8} ]^0 * [\frac{1}{8} ]^5 * [\frac{1}{2} ] ^0[/tex]

    [tex] P( G =  0 ,  Y = 5 ,  R = 0) =  0.0000305176 [/tex]

Also  

     [tex] P( G =  1 ,  Y = 3 ,  R = 1)=  \frac{5!}{ 1! * 3! * 1!} *  [\frac{3}{8} ]^1 * [\frac{1}{8} ]^3 * [\frac{1}{2} ] ^1[/tex]

    [tex] P( G =  1 ,  Y = 3 ,  R = 1)=  0.0073242 [/tex]  

[tex]P(G = R ) =  0.13184 +  0.0000305176+ 0.0073242 [/tex]

[tex]P(G = R ) =  0.13919  [/tex]

Answer:

No

Step-by-step explanation:

42 x 42 = 1764

43 x 43 = 1849

1764 + 1849 = 3613

and the sqaure roof of 3613 is 60.11

60.11 does not equal 58

so no it is not a right triangle

Answer:

(1)  n = 9

(2) n = 15

(3) r = -8

Plz mark brainliest:)

Answer:

Step-by-step explanation:

1.4=n/9+3

4-3=n/9

1=n/9 cross multiply

2. -7=-8+n/15

-7+8=n/15

1=n/15 Cross multiply

n=15

3.-11=r/2-7

-11+7=r/2

-4=r/2cross multiply

-8=r

r=-8

Answer:

The answer is -17.

Step-by-step explanation:

Well since the answer turns out to be a negative, one of the numbers has to be negative.(not all cases but for this one, yes)You have to add 12+5 and you get 17. This has to be a negative because the answer is a negative.

Answer:

a = [tex]\frac{h-r}{b}[/tex]

Step-by-step explanation:

Given

h = ab + r ( subtract r from both sides )

h - r = ab ( isolate a by dividing both sides by b )

[tex]\frac{h-r}{b}[/tex] = a

Answer: 1.2 individual signing up the day of the activitiy get charged 20% more

Step-by-step explanation:

We have a community center that charges x dollars for a summer activity if individuals are signed up before the day of the activity but if  individuals who sign up on the day of the activity are charged a fee of x + 0.20x dollars.

We have to determine which expression represents the fee for signing up the day of the activity and investigate what does it mean about the fee.

Equation modelling of a process is a way to formulate the given process mathematically. Generally, it is used in such problems where something is produced on giving some input.

According to question, we have the following equation describing the charging rates -

f(x) = x + 0.2x = x + [tex]\frac{1}{5}x[/tex]

In this the expression, the part  [tex]\frac{1}{5}x[/tex] represents the fee for signing up on the day of the activity.

It also indicates that if you you are late for sign up and you are signing on the day of the activity then you will have to pay an extra fine of [tex]\frac{1}{5}[/tex] times of the fees if you signed up before the day.
