Answer:
V ≈ 552.9 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height ) , then
V = π × 4² × 11 = π × 16 × 11 = 176π ≈ 552.9 cm³ ( to the nearest tenth )
Answer: n = 2401
Step-by-step explanation:
Given;
Confidence level = 2% - 99%
n = ? ( which is the sample size is unknown ).
Solution:
Where;
n = [z/E]^2*pq
Since no known value for ( p ) estimate is given, the "least biased" estimate is p = 1/2
Substituting the given data into the formula.
n = [1.96/0.02]^2(1/2)(1/2)
n = 2401
The minimum number of truck drivers the statistician needs to sample for an accurate result is 2401
Answer:
5.909
Step-by-step explanation:
The quotient is approximately ...
15.58701/2.638 ≈ 5.9086467...
The least-precise contributor to this calculation has 4 significant digits, so it would be appropriate to round the result to 4 significant digits:
5.909
_____
<em>Additional comment</em>
The quotient has a 659-digit repeating decimal fraction starting with 6467....
