Answer:
C.) The relationship is proportional
Step-by-step explanation:
If D is true, then it is not proportional, constants of proportionality must not include multuplting or subtracting from anything.
Also quick way to tell— the line doesn’t start from 0,0
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

Step-by-step explanation:
Answer:
The picture shows the answer on the graph
Step-by-step explanation:
-2=-3/4×(x-6)
Distribute -3/4 through the parenthesis
-2= -3/4x+9/2
Multiply both sides of the equation by 4
-8=-3x+18
Move the variable to the left side and change its sign
3x-8=18
Move constant to the right side and change its sign
3x=18+8
Add the numbers
3x=26
Divide both sides of the equation by 3
x=26/3
Alternative Form- x=8 2/3 or x=8.6
