Answer: the predictive value positive of the test is 0.7
Step-by-step explanation:
Given that;
Predicted
Diesease No-Diesease Tt
Actual Diesease 225 75 300
No-Diesease 25 175 200
250 250 500
so finding the predictive value positive of the test,
predictive negative value = (175 / (75+175) )
= 175 / 250
= 0.7
Therefore the predictive value positive of the test is 0.7
Answer:
X=3,y=-4
Step-by-step explanation:
The only change is x so you could figure it out that way or do this:
4x=12 by subtracting the secound equation by the first one (since both y's are being multiplied by the same thing you can do this to cancel them out while making one equation). and than figure out x=3 from there you input that into eithger equation to figure out y. Hope this helped!
