Among 143 subjects with positive test results, there are 24 false positive results; among 157 negative results, there are 3 false negative results. These results can be put in the following tabular form: Used Did not use Positive Test Result 119 24 Negative Test Result 3 154 If one of the test subjects is randomly selected, find the probability that the subject tested negative or used marijuana. Give answer as a decimal rounded to 2 decimal places.

all it means is function 3

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

answer: (3,11) is your answer.
