Answer: (B) 53%
Step-by-step explanation:
Given : The probability that registered voters are Democrats P(D)= 0.60
The probability that of registered voters are Republicans P(R)= 100%-60%=40% =0.4
The probability that the registered voters who are Democrats are expected to vote for Candidate A : P(A|D)=0.75
The probability that the registered voters who are Republicans are expected to vote for Candidate P(A|R) = 0.20
Then by using Law of total probability , the probability of the registered voters are expected to vote for Candidate A :-
Hence, the percent of the registered voters are expected to vote for Candidate A=53%
Hence, the correct option is (B).

Answer:
Step-by-step explanation:
Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.
From the equation y = 0.18x
Divide both sides by the coefficient of x i.e 0.18
y/0.18 = 0.18x/0.18
y/0.18 = x
Hence the function of the variable x = y/0.18
b) Given the amount of the bill as y and x is the tip in dollars.
Given y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;
Since x = y/0.18
x = $4.95/0.18
x = $27.5
<em>Hence the bill is $27.5</em>
