Answer:
i believe the answer would be y= -x-4
Step-by-step explanation:
a line that is perpendicular, will have and opposite reciprocal slope, so:
the slope of the line y=x-4 is 1, and the reciprocal of 1 is also 1.
now take the opposite of it, which is -1.
so the perpendicular line equation would be y=-x-4
i hope this helps :D

Answer: 2285
Step-by-step explanation:
Formula to find the sample size is given by :-

, where p = prior estimate of population proportion.
E= Margin of error.
= z-value for confidence interval of c.
Given : Confidence interval : 95%
From the z-value table , the z-value for 95% confidence interval = 
The General Social Survey reported a sample where about 61% of US residents thought marijuana should be made legal.
i.e. the prior estimate of population proportion of US residents thought marijuana should be made legal : p=0.61
[∵ sample proportion is the best estimate for population proportion.]
Margin of error : E= 2%=0.02
Now, the required minimum sample size would be :-

Simplify ,

Thus , we need to survey <u>2285</u> Americans .
