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]
The ANOVA procedure is a statistical approach for determining whether or not a. the means of two samples are equal b. the means of more than two samples are equal c. the means of two or more samples are equal d. the means of two or more populations are equal
Answer:
d. the means of two or more populations are equal
Step-by-step explanation:
ANOVA is a short term for analysis of variance and it was developed by the notable statistician Ronald Fisher. It is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors. In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.
The ANOVA procedure is a statistical approach for determining whether or not the means of two or more populations are equal through the use of a F-test or null hypothesis.
The ANOVA procedure is a statistical approach for determining :
d. the means of two or more populations are equal
The ANOVA procedure is a statistical approach for determining the means of two or more populations are equal .

Let the missing angle be ∠y . Then :-
∠y =∠115°
Their measure will be equal as they are alternate interior angles whose angle measure will be equal when on two parallel lines with a transversal .
Therefore , the missing angle = 115° .
Solution (6) :Let the missing angle be ∠x . Then :-
∠x = ∠66°
Their measure will be equal as they alternate interior angles .
Therefore , the ,measure of the missing angle is = 66° .
Solution (7) :Let the missing angle be ∠m . Then :-
∠m + ∠50° = 180°
∠m = 180 - 50
∠m = 130°
The sum of these two angles will be equal to 180° as they are interior angles on the same side of transversal .
Therefore , the measure of the missing angle will be = 130° .
Solution (8) :Let the missing angle be ∠n . Then :-
∠n + ∠105° = 180°
∠n = 180 - 105
∠n = 75°
The sum of these two angles will be will be equal to 180° as they are interior angles on the same side of transversal .
Therefore , the measure of the missing angle will be = 75° .
Answer:
5) 115- alternate interior angles
6) 66 - alternate interior angles
7) 130 - consecutive interior angles
8) 75 - consecutive interior angles

Marcus reads in a magazine article that 62% of teenagers prefer Batman over Iron Man. He decides to test this so he takes a simple random sample of 50 people at Wal-Mart on a Sunday afternoon. What is the probability that he finds exactly 40 Batman fans? Round to the nearest thousandth.
Answer:
The probability is 0.003
Step-by-step explanation:
If 62% prefers Batman, the percentage that prefers Iron man will be (100-62)% = 38%
So the probability of finding a teenager that likes batman will be 62/100 = 0.62
The probability of finding a teenager that prefers iron man will be 38/100 = 0.38
Now, we want to find the probability that out of 50 people at Walmart on a Sunday, exactly 40 prefers Batman
We can use the Bernoulli approximation of the binomial theorem ;
let probability of liking Batman be q and that of iron man be q
Thus the approximation will be;
P(X = 40) = 50 C 40 (0.62)^40 (0.38)^10
= 0.003200147531
To the nearest thousandth, this is 0.003

Answer:
C. a quantity used as a standard measurement
Step-by-step explanation:
A unit is a universally acceptable system of measurement. The system is majorly referred to as the international standard of units i.e (SI) units.
Since physical quantities could be categorize as either fundamental or derived. The use of units in measurement is very essential, because it relates the magnitude measured to the physical quantity.
The units of measurement tells what physical quantity has been measured.

y=-2x+3/2 or y=-2x-3/2
Step-by-step explanation:
so the line starts at the negative 2 on the y-axis and -3 is on the x-axis then so you start at the -2 on the y-axis and go over and count how many times it goes over and then count how many times it goes down to the next dot.
Horizontal lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase left angle is 75 degrees. At the intersection of lines b and e, the uppercase right angle is 115 degrees. At the intersection of lines a and f, the bottom right angle is 75 degrees.
Which lines are parallel? Justify your answer.
Lines a and b are parallel because their alternate exterior angles are congruent.
Lines a and b are parallel because their same side exterior angles are supplementary.
Lines e and f are parallel because their alternate exterior angles are congruent.
Lines e and f are parallel because their same side exterior angles are congruent.
Lines e and f are parallel because their alternate exterior angle is congruent. Option C is correct.
Find the diagram attached;
The point where two lines meet is known as an angle.

Answer:
a. y=30(20)+800
y=1400
b. 700
Step-by-step explanation:
Answer: Answers are in the steps, please read carefully.
Step-by-step explanation:
A. Since each of the twenty people paid $30 each and an $800 was raised, then the expression will be multiplying 20 by 30 and adding it to 800. To find the value of the expression, multiply 20 by 30 then add it to find the result.
Expression: 20(30) + 800
Value of Expression: 600 + 800 = 1400

What goes in each drop down menu?
Answer:
x = 95 y = 137 z = 128
Step-by-step explanation:
z = 180 - 52 = 128 z plus 52 have to be equal to 180
Angle coincident of x is equal to 180 - (45 + 50) = 85
x = 180 - 85 = 95
Angle coincident of y is equal to 180 - (85 + 52) = 43
y = 180 - 43 = 137
