The margin of error is ±2%
<h3>What is Margin error?</h3>
A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.
Let x be margin of error and y be the percentages of the population.
So,
y-x =33%
y +x = 37%
Solving above equations
2y= 70
y= 35%
and x= 2%
Hence, the margin of error is ±2%.

First you need to find the slope of the line. So what you need to do is y^2-y^1 / x^2-x^1
(x^1, y^1) (x^2, y^2)
( -1, 7) ( 2, 10)
10-7/ 2- (-1)
3/3=1
slope is 1
I got 8 as the y intercept. Reason how is that I made a table. And what I did was go back instead of going forward.
x y
-1 7
0 8
1 9
2 10
The answer would be x= 1 y= x + 8 y=8 But the answer choice you listed for A. would not match up the 2 coordinate you gave. Make sure a. should be x= 1 y= x + 8 y=8, not -x y= 8-x y=8
Rational expressions are multiplied and divided the same way numeric fractions are.
Use the
Binomial expansion theorem to find and simplify each
term.
Man that was a lot to type out, hopefully i helped, and Gosh I hope I get a brainly for all that freaking typing. hehe~ ^.^
