Answer:
The angular velocity is 8.38 radians per minute
Step-by-step explanation:
From the question,
It takes 45 seconds to complete a full revolution,
That is, 1rev/45secs
First, we will convert this to revolutions per minute (rev/min)
1rev/45secs =
= 4/3 rev/min
Now, we will convert this to radians per minute (rad/min)
1 revolutions = 2π rad
4/3 rev/min =
= 8.38 rad/min
Hence, the angular velocity is 8.38 radians per minute

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).
