Volume of the cone = 1/3 π r² h
Volume of the cone = 1/3 π (300÷2)² (150) = 3, 534,291.74 m³
Answer: 3, 534,291.74 m³
The answer is definitely B
Answer:
Step-by-step explanation:
from08:15 to 12:15=4hour
from1300 to 1730=4 and half hour
altogether # of hours worked=8 and half hour
8 and half hour x $12/hr=$102
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%
