Answer:
P = 0.332
Step-by-step explanation:
The probability of having the disease is 0.08
The probability that the test predicts with accuracy is 0.7.
We need to find the probability that the test positive for the disease.
Several cases may occur.
Case 1.
You have the disease and the test predicts it accurately

Case 2
You do not have the disease and the test predicts that you have it

Then the probability that the test predicts that you have the disease is the union of both probabilities P1 and P2

Answer:3x
Step-by-step explanation:
If 2x+y=2y−x, then the value of y in terms of x can be
3x
First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
