Answer:
Step-by-step explanation: x=1
4:7=m:42
7*6=42
so multiply 4*6 also and m=24
or 4:7=24:42
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
Let S3={I, 1, 2, 3, 4, 5}
Then S3 is an non-Abelian group under composition because ab DNE ba
yet A3 is a normal subgroup of S3 which is commutative and contains permutations of even order
you can also take mappings of this group G
onto G'
may be an isomorphism perhaps
