Answer:
The point estimate is 0.45.
The 95% error margin is 0.042 = 4.2 percentage points.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is given by:
Point estimate
We have that 
So the point estimate is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Error margin:
The 95% error margin is 0.042 = 4.2 percentage points.
Answer:
Step-by-step explanation:
(x - 3)/2 = -1/2
x - 3 = -1
x = 2
(y + 1/2)/2= 3
y + 0.5 = 6
y = 5.5
(2, 5.5) the other endpoint
Answer:
idk
Step-by-step explanation:
cus i dont know
What all they have in common is that they all form sorta of an L shape I'm pretty sure
4(x+3)=4x+12 because when you have the ( ) you have to multiply the front # with the # inside it.
I hope that my image explains it I’m not really good at explaining things
