You can use 78 = 0.55(w) and
78/x = 55/100. They both lead to the same answer.
The correct answer is B 1/8.
Hope this helps!
Answer:
The margin of error for the confidence interval is of 0.08 = 8%.
Step-by-step explanation:
A confidence interval has two bounds, an upper bound and a lower bound. The margin of error is half the subtraction between these two bounds.
In this question:
Lower bound: 0.5
Upper bound: 0.66
Margin of error: (0.66 - 0.5)/2 = 0.16/2 = 0.08
The margin of error for the confidence interval is of 0.08 = 8%.
The answer is D. Since the x line is seconds and y is feet traveled it would mean that the train travels 180 feet in 3 seconds
