the probability that a test correctly classifies as positive individuals who have preclinical disease
Step-by-step explanation:
Sensitivity represents the true positive percentage
Lets take an example if there is 90% sensitivity that means there are 90% people who have the target disease considered the test positive
So according to the given options, it is the probability in which if the test is done in a correct manner so this means that the positive individuals have the preclinical disease
Therefore the first option is correct
If you are just dividing percent's, then each grade would have 12.5 percent.
Answer:

4. a + c = 1600
Step-by-step explanation:
Simplify 6 – 4x – 2 + x
Combine like terms:
6 - 2 = 4
-4x + x = -3x
-3x + 4, or (A) is your answer

Simplify 5 – 2x – 3 + x
Combine like terms:
5 - 3 = 2
-2x + x = -x
-x + 2, or (B) is your answer
