A serological test is being devised to detect a hypothetical chronic disease. 500 individuals were referred to a laboratory for
andriy [413]

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

What is the product?<br>(4x) (-345 (-23)​
olga_2 [115]

Answer:

Step-by-step explanation:

You first want to get rid of the numbers which are in parenthesis

(-345(-23)

This is a multiplication between negative numbers

The law of signs in mathematics states that negative times negative equals positive

(-) (-) = +

(-345(-23)= 7935

Then we multiply the number which is outside of the parenthesis (4x)

(4x)7935= 31740x
