Number of links = 100
Shape of each link = Circle
Radius = 2.5
Area = πr²
= 3.14×2.5×2.5
= 19.625
Now for 100 links
19.625×100
1962.5Cm²
Cost = 1962.5 × 0.06
= $117.75

Answer:
its 1/3
Step-by-step explanation:
The 95% confidence interval for a population mean has a margin of error (E) of 41
The confidence interval for a population mean is given by:
Confidence interval = μ ± E = (μ - E, μ + E)
Where μ is the mean and E is the margin of error.
Since the confidence interval is (428, 510), hence:
μ - E = 428 (1)
μ + E = 510 (2)
Subtracting equation 1 from equation 2:
2E = 82
E = 41
μ - E = 428
μ -41 = 428
μ = 469
Hence the margin of error (E) is 41
