Answer:
b = 2x²
Step-by-step explanation:
Let the number of bacteria = x
Every hour, the number of bacteria doubles itself, = x * x = x²
But the bacteria started with 2g,
The number of bacteria present is equal to
2 * x² = 2x².
At every hour, the growth of the bacteria is at 2x²
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
