Answer:
The margin of error is 0.1215
Step-by-step explanation:
A confidence interval has two bounds, a lower bound and an upper bound. The margin of error is the difference between these two bounds, divided by 2.
In this problem, we have that:
Lower bound: 0.5627
Upper bound: 0.8057
What is the margin of error?
(0.8057 - 0.5627)/2 = 0.1215
The margin of error is 0.1215

Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
