Answer:
0
Step-by-step explanation:
Since you didn't attach an image of the graph I'll have to do this the hard way.
x + 2y = 2 (1)
2x + 4y = -8 (2)
x + 2y = -4 (Divide equation (2) by 2)
0 = 6 (Subtract the third equation from the first)
Since 0 is not equal to 6 the answer is No Solutions.
no solutions
x+2y=2
2x+4y=−8
Multiply the first equation by -2
-2x -4y = -4
Add this to the second equation
-2x-4y = -4
2x +4y = -8
--------------------------
0x+0y = -12
0 = -12
This is never true so there are no solutions

Margin of error = z√(p(1-p)/n)
Given
p-hat = 0.43
n = 270
z at 99% confidence interval = 2.576
Substitute
MOE = 2.576√0.43(1-0.43)/270
MOE = 2.576√0.43*0.57/270
MOE = 2.576√0.2451/270
MOE = 2.576*0.030129
MOE = 0.078
Hence the margin og error is 0.078
