Step-by-step explanation:
Since the variables "x" and "y" are inversely related, the equation has the following form:
Where "k" is the constant of variation.
In this case we know that:
So, the equation is:
Therefore, substituting the given values of "x" into the equation, we get:
a. For →
b. For →
c. For →
d. For →
Answer:
the number is 3
Step-by-step explanation:
4-5x=11
11+4=15
15÷5=3
4-5(3)=11
Using conditional probability, it is found that there is a 0.4235 = 42.35% probability that the patient really is HIV positive.
Conditional Probability
In which
- P(B|A) is the probability of event B happening, given that A happened.
- is the probability of both A and B happening.
- P(A) is the probability of A happening
In this problem:
- Event A: positive test.
- Event B: HIV positive.
The percentages involving a positive test are:
- 95% of 3%(positive)
- 4% of 100 - 3 = 97%(not positive).
Hence:
The probability of both having a positive test and being HIV positive is:
Then, the conditional probability is:
0.4235 = 42.35% probability that the patient really is HIV positive.
