Step-by-step explanation:
Answer:
I believe it is A
Step-by-step explanation:
I dont quite remember the formula, but I belive that 30 would be correct because if im remembering correctly the formulas are "a + b = c" and "c - (a/b) = (a/b)
a/b = a or b, depending what they give you
Answer:
n=601
Step-by-step explanation:
Formula used:
![n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}](https://tex.z-dn.net/?f=n%3Dz%28%5Cfrac%7B%5Calpha%20%7D%7B2%7D%29%5E2%5Cfrac%7Bp%281-p%29%20%7D%7BE%5E2%7D)
Solution:
![n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}](https://tex.z-dn.net/?f=n%3Dz%28%5Cfrac%7B%5Calpha%20%7D%7B2%7D%29%5E2%5Cfrac%7Bp%281-p%29%20%7D%7BE%5E2%7D)
Where,
![\frac{\alpha }{2}=0.025](https://tex.z-dn.net/?f=%5Cfrac%7B%5Calpha%20%7D%7B2%7D%3D0.025)
As there is no previous estimate for p
Then, p=0.5
Here on using the table
![z(\frac{\alpha }{2}) =1.959963985](https://tex.z-dn.net/?f=z%28%5Cfrac%7B%5Calpha%20%7D%7B2%7D%29%20%3D1.959963985)
Also,
E=0.04
p=0.5
Thus,
n=600.2279407
On approximating the value,
n=601
Answer:
the domain of the relation is C
