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

Maslowich

Answer: 2285

Step-by-step explanation:

Formula to find the sample size is given by :-

n=p(1-p)(\dfrac{z_c}{E})^2

, where p = prior estimate of population proportion.

E= Margin of error.

z_c = z-value for confidence interval of c.

Given : Confidence interval : 95%

From the z-value table , the z-value for 95% confidence interval = z_c=1.96

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 :-

n=0.61(1-0.61)(\dfrac{1.96}{0.02})^2

Simplify ,

n=0.2379\times9604=2284.7916\approx2285

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