Answer:
- probability of a false positive test result = 0.010
- The non-drug user will suffer from the result since it is positive
Step-by-step explanation:
The probability that the test result is a false positive
total number of cases studied (n) = 38 + 12 + 19 + 29 = 98
number of false positive cases ( x ) = 1
probability of false positive result = x / n = 1/98 = 0.010
The non-drug user will suffer from the result since it is positive
Answer:
it is A because when you look at the answer they don't make sense and there is no answer D

![\frac{v + 9}{3} = 8](https://tex.z-dn.net/?f=%20%5Cfrac%7Bv%20%2B%209%7D%7B3%7D%20%3D%208)
Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.
3 × (v + 9) = 8 × 3
Simplify.
3v + 27 = 24
Then, subtract both sides by 27.
3v = 24 - 27
Simplify.
3v = -3
Divide both sides by 3.
v = -1
~Hope I helped!~
The answer is 291.60 because you multiply 12 x 9 which equals 108 then multiply 108 x 2.70 which equals 291.60
