Answer:
yes
Step-by-step explanation:
Remember
∛(xy)=(∛x)(∛y)
3rd power
factor inside and group
384=2*2*2*2*2*2*2*3=2^3*2^3*2*3=2^3*2^3*6
∛384=(∛2^3)(∛2^3)(∛6)=(2)(2)(∛6)=4∛6
C
Let
μ = population mean
σ = population std. deviation.
n = sample size.
At 95% confidence level, the confidence interval is
(μ - 1.96y, μ + 1.96y),
where y = σ/√n.
Therefore
μ - 1.96y = 6.5 (1)
μ + 1.96y = 12.5 (2)
Add (1 and (2) to obtain
2μ = 19
μ = 9.5
The calculated value of μ is within the interval (6.5, 12.5).
Answer:
The statement "There is a 95% probability that the true population mean is between 6.5 and 12.5" is True.

Answer:
D. 6
Step-by-step explanation:
The height of the larger cylinder is 15/5 = 3 times the height of the smaller one. Because the cylinders are similar, you know that the radius of the larger one will have the same multiplier of the radius of the smaller one.
The larger radius is 3 × 2 = 6.
