Complete Question
If minor arc AB measures 9 inches, what is the length of the radius of circle C? Where the radians is 0.75 radians
If necessary, round your answer to the nearest inch. 6 inches 12 inches 18 inches 24 inches
Answer:
12 inches
Step-by-step explanation:
The formula for Arc length =
Arc length = r θ
θ = 0.75
Arc length = 9 inches
Hence:
r = 9/ θ
r = 9/0.75
r = 12 inches
Answer:
P = 0.4812
Step-by-step explanation:
First, we need to use here two expressions and then do the calculations.
The first one is the conditional probability which is:
P(B|A) = P(A∩B)/P(A) (1)
The second expression to use has relation with the Bayes's theorem which is the following:
P(D|C) = P(C|D)*P(D) / P(C|D)*P(D) + P(C|d)*P(d) (2)
Now, the expression (2) is the one that we will use to calculate the probability of a selected random bicyclist who tests positive for steroids.
So, in this case, we will call C for positive and D that is using steroids and d is the opposite of d, which means do not use steroids.
Then, the probabilities are the following:
P(D) = 8% or 0.08
P(C|D) = 96% or 0.96
P(C|d) = 9% or 0.09
P(d) = 1 - 0.08 = 0.92
With these data, let's replace in expression 2
P(D|C) = 0.96 * 0.08 /0.96 * 0.08 + 0.09*0.92
P(D|C) = 0.0768 / 0.1596
P(D|C) = 0.4812 or 48.12%
A= -8
B= -24
4*-2= -8
48/-2=-24
