Answer:

25.12 millimeters is your answer.

Step-by-step explanation:

Circumference can be solved by using the equation:

c = 2πr or c = πd

Note that diameter (d) is equal to 8. Plug in 8 for d.

c = (8)(π)

Also note that π = 3.14. Multiply

c = (8)(3.14)

c = 25.12 millimeters.

25.12 millimeters is your answer.

Answer: 25.132

Step-by-step explanation: The circumference of a circle is always 2(pi)(r). With r being the radius which is ALWAYS half the diameter. So your radius is 4 millimeters. So multiply 2(pi)(4).

A commuter crosses one of three bridges, A, B, or C, to go home from work. The commuter crosses bridge A with probability 1/3, c
mihalych1998 [28]

Answer:

0.1333 = 13.33% probability that bridge B was used.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Arrives home by 6 pm

Event B: Bridge B used.

Probability of arriving home by 6 pm:

75% of 1/3(Bridge A)

60% of 1/6(Bridge B)

80% of 1/2(Bridge C)

So

P(A) = 0.75*\frac{1}{3} + 0.6*\frac{1}{6} + 0.8*\frac{1}{2} = 0.75

Probability of arriving home by 6 pm using Bridge B:

60% of 1/6. So

P(A \cap B) = 0.6*\frac{1}{6} = 0.1

Find the probability that bridge B was used.

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1}{0.75} = 0.1333

0.1333 = 13.33% probability that bridge B was used.
