Answer:
And the margin of error with this one:
Step-by-step explanation:
Assuming that the parameter of interest is the sample mean 
. And we can estimate this parameter with a confidence interval given by this formula:
(1)
For this case the confidence interval is given by (1.9, 3.3)
Since the confidence interval is symmetrical we can estimate the sample mean with this formula:
And the margin of error with this one:
Answer:
588
Step-by-step explanation:
((16 - (4/2))^2) × 3 Simplify the inner parentheses
((16 - 2)^2) x 3 Solve inner parentheses again
((14)^2) x 3 Solve exponents
196 x 3 Multiply

Answer:
Radius, Diameter and Circumference
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
Step-by-step explanation:
1/3 - 1/6
= 2/6 - 1/6
= 1/6
so, 1/3 - 1/6 = 1/6
