According to exit polling from the 2014 U.S. midterm elections, 36% of voters had a household income less than $50,000, while 64% had a household income of at least $50,000. Forty-three percent of voters from house-holds making less than $50,000 voted for the Republican party in the election, while 55% percent of voters from households making at least $50,000 voted Republican. What is the probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000
Answers
Answer:
0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Republican
Event B: From a household that makes at least $50,000.
Probability of Republican:
43% of 36%(makes less than $50,000).
55% of 64%(makes more than $50,000).
So
[tex]P(A) = 0.43*0.36 + 0.55*0.64 = 0.5068[/tex]
Republican and from a household that makes at least $50,000.
55% of 64%. So
[tex]P(A \cap B) = 0.55*0.64 = 0.352[/tex]
What is the probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.352}{0.5068} = 0.6946[/tex]
0.6946 = 69.46% probability that a randomly selected Republican voter from the exit poll is from a household that makes at least $50,000.

Subtract 2/3 and 1/4.
Answers
Answer:
5/12
Step-by-step explanation:
Find common denominators. Note that what you multiply to the denominator, you must multiply to the numerator as well. The common denominator is 12:
(2/3) * (4/4) = (8/12)
(1/4) * (3/3) = (3/12)
Subtract:
(8/12) - (3/12) = (8 - 3)/12 = 5/12
5/12 is your answer.

Answers
Answer:

Step-by-step explanation:
5x+x is basically 5x+1x which is 6x since x has an "invisible one" in front of it.
x+x+4x is 2x+4x which is 6x
hope this helps. :)
Answer:
4 and 5
Step-by-step explanation:
9x - 3 is 6x
5x + x can be 6x because there's is a x next to it that means it can be any number so if the number is suppose to become 6x we need to add 1 to both sides, and the a swer will be 6x.

Taina found the area of a table in the shape of a trapezoid. The height of the trapezoid is 10 ft, base one is 6 ft and base two is 5 ft. Taina says the area of the figure
is 110 square foot inches. What mistake did Taina make? What is the actual answer?
Answers
9514 1404 393
Answer:
wrong formulawrong unitsStep-by-step explanation:
The formula for the area of a trapezoid is ...
A = 1/2(b1 +b2)h
A = (1/2)(6 ft +5 ft)(10 ft) = 55 ft²
The numerical value of the answer would be 110 if we "forgot" to multiply by 1/2.
The area units would be "square foot inches" if inch dimensions crept into the problem somewhere.

Classify the triangle
Answers
Answer:
This triangle is an isosceles acute
Step-by-step explanation:
First lets define each classification
scalene - no equal sides
isosceles - two equal sides
equilateral - all equal sides
acute - all angles have a measure of less than 90 degrees
right - has a right angle (90 degree angle)
obtuse - has an angle that has a measure of more than 90 degrees
Now lets classify
The triangle has two equal sides (indicated by the little line on the top and bottom side) therefore it is an isosceles triangle
We know its an acute triangle because the one angle given is not a right angle nor a obtuse angle meaning that the other two angles are going to have a measure of less than 90 degrees
So we can conclude that this is an isosceles acute triangle
