Hi there!
We can use "Completing the Square" to solve:
f(x) = x² - x + 2
Group the variables. The "x" term's coefficient will be divided by two and squared for the third part of the trinomial. Remember to subtract by the third term:
f(x) = x² - x + (1/2)² + 2 - (1/2)²
Group:
f(x) = (x - 1/2)² + 2 - 1/4
Rewrite:
f(x) = (x - 1/2)² - 7/4
Thus, the first answer is correct.
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
above is the solution to the question
