Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
From the question we are told the confidence level is 97.5% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally we will assume the sample proportion to be 
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20)
=> ![n = [\frac{2.241}{0.02} ]^2 *0.5 (1 - 0.5 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B2.241%7D%7B0.02%7D%20%5D%5E2%20%2A0.5%20%281%20-%200.5%20%29%20)
=>
Answer:
2
Step-by-step explanation:
To find the slope, we use the equation
m = (y2-y1)/(x2-x1)
Since the have the points (2,-4) and (4,0)
m = (0--4)/ (4-2)
= (0+4)/(4-2)
= 4/2
=2
Answer:
