Answer:

0.7385 = 73.85% probability that it is indeed a sample of copied work.

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: Identified as a copy

Event B: Is a copy

Probability of being identified as a copy:

80% of 15%(copy)

100 - 95 = 5% of 100 - 15 = 85%(not a copy). So

P(A) = 0.8*0.15 + 0.05*0.85 = 0.1625

Probability of being identified as a copy and being a copy.

80% of 15%. So

P(A \cap B) = 0.8*0.15 = 0.12

What is the probability that it is indeed a sample of copied work?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.12}{0.1625} = 0.7385

0.7385 = 73.85% probability that it is indeed a sample of copied work.

Which graph models the function f(x) = -4(2)x?
scoray [572]
It is C. 

If you type in your calculator "Y=" and then " -4(2)^x " and click "GRAPH" you will see a descending graph, from left to right, that looks EXACTLY like the third graph in option C.
