Answer:
It would be 2
Step-by-step explanation:
Since they are looking for only 1 significant fig. you would round the number that would make this correct, for example:
You would look at 1.7 and ignore the others...
7 is greater than 5 so it'll affect the 1
And that how you get 2 : )
Answer: y-intercept: (0,-6)
Answer:
Closure Property of Addition
Step-by-step explanation:
Step-by-step explanation:
N=km
72=k×48
72=48k
k=72/48
k=1.5
N=1.5m
N=1.5×144
N=216
Solution:
Population in the city= 10,000
As genetic condition affects 8% of the population.
8 % of 10,000
![=\frac{8}{100}\times 10,000=800](https://tex.z-dn.net/?f=%3D%5Cfrac%7B8%7D%7B100%7D%5Ctimes%2010%2C000%3D800)
As, it is also given that, there is an error rate of 1% for condition (i.e., 1% false negatives and 1% false positives).
So, 1% false negatives means out of 800 tested who are found affected , means there are chances that 1% who was found affected are not affected at all.
So, 1% of 800 ![=\frac{1}{100}\times 800=8](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B100%7D%5Ctimes%20800%3D8)
Also, 1% false positives means out of 10,000 tested,[10,000-800= 9200] who are found not affected , means there are chances that 1% who was found not affected can be affected also.
So, 1% of 9200 ![=\frac{1}{100}\times 9200=92](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B100%7D%5Ctimes%209200%3D92)
1. Has condition Does not have condition totals = 800
2. Test positive =92
3. Test negative =8
4. Total =800 +92 +8=900
5. Probability (as a percentage) that a person has the condition if he or she tests positive= As 8% are found positive among 10,000 means 9200 are not found affected.But there are chances that out of 9200 , 1% may be affected
![=\frac{\text{1 percent of 9200}}{9200}\\\\ \frac{\frac{1}{100}\times 9200}{9200}=\frac{92}{9200}\\\\ =0.01](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7B1%20percent%20of%209200%7D%7D%7B9200%7D%5C%5C%5C%5C%20%5Cfrac%7B%5Cfrac%7B1%7D%7B100%7D%5Ctimes%209200%7D%7B9200%7D%3D%5Cfrac%7B92%7D%7B9200%7D%5C%5C%5C%5C%20%3D0.01)
that is Probability equal to 0.01 or 1%.
