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:

B. 7x + 6y

Step-by-step explanation:

  3x + 7y -5x +9x -y

Step-by-step explanation:

Tax = 8% of 23

      = [tex]\frac{8}{100}*23[/tex]

      = [tex]\frac{184}{100}[/tex]

      = $ 1.84

Answer

The answer is $1.84

Step-by-step explanation

The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax.

Answer:

Option (d)

Step-by-step explanation:

If the current salary of Sione is represented by the function m(t - 1),

Next year his salary m(t) gets hike of 3%.

So, the next year salary of Sione will be represented by,

m(t) = m(t - 1) + 3% of m(t - 1)

      = m(t - 1) + 0.03 × m(t - 1)

      = m(t - 1)(1 + 0.03)

      = 1.03m(t - 1)

Since, at the end of year 1 his salary was $55000,

Recursive function will be,

m(t) = 1.03m(t - 1) = 55000

Therefore, Option (d) will be the answer.

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:

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

4/9 is the answer

Answer:

f(x) = (x - 6)/(3/2)

Step-by-step explanation:

Answer:

a=60

Step-by-step explanation:

since there are 6 total "a" values (2 angles worth just a, 2 angles worth 2 a)

you divide the total angle number by 6: 360/6=60

a=60

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:

5

Step-by-step explanation:

9×5/9=45/9

=5

just multiply the stuff in parantheses and then add and then divide.

Answer:

5

Step-by-step explanation:

3^2*(2+3); 9*5=45

(2+1)*3; (3)*3=9

So 45/9 =5
