Answer:
0.4929 = 49.29% probability that he voted in favor of Scott Walker
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Having a college degree.
Event B: Voting for Scott Walker.
They found that 57% of the respondents voted in favor of Scott Walker.
This means that 
Additionally, they estimated that of those who did vote in favor for Scott Walker, 33% had a college degree
This means that 
Probability of having a college degree.
33% of those who voted for Scott Walker(57%).
45% of those who voted against Scott Walker(100 - 57 = 43%). So
What is the probability that he voted in favor of Scott Walker?
0.4929 = 49.29% probability that he voted in favor of Scott Walker
Answer:
<em>2.399</em>
Step-by-step explanation:
Given the trigonometry expression:
tan(sin^-1((-12/13))
We are to find the exact value
tan(sin^-1((-12/13)) = tan(sin^-1((-0.9231))
tan(sin^-1((-12/13)) = tan(-67.38)
Also note that tan(-theta) = -tan theta
tan(-theta) = -tan67.38
tan(-67.38) = -2.399
<em>The exact value is 2.399</em>
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+ 
= 
, that is
1 + cot²θ = cosec²θ ← as required
Answer:
x=1
x=-5
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem there are two intersection points
so
The system has two solutions
we have
one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)
see the attached figure
therefore
x=1
x=-5
