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 are the choices ? ? It's about 69 miles or 111 km.
Answer:
I don't know 9,2
Step-by-step explanation:
9,2
To write an improper fraction as a mixed number, we simply need to divide the numerator (number on the top of the fraction) by the denominator (number on the bottom of the fraction). Then, the amount of times that the denominator goes into the numerator is written as the whole number value in the mixed number, and the remainder stays where the numerator is.
In this expression, we have the improper fraction

. Let us divide to find our numbers:
14 ÷ 5 = 2 R 4
So we have all we need now. We can see that 5 goes into 14 twice with a remainder of 4, so we can now write our mixed number.

And there you have it.

written as a mixed number is

.
