Answer:
V = 15 pi ft^3
Step-by-step explanation:
The volume of a cone is given by the formula
V=1/3 pi r^2 h
We know the radius and the height
V = 1/3 pi *(3)^2*5
V = 1/3 *pi*9*5
V = 15 * pi
Leave in terms of pi
V = 15 pi ft^3

Answer:
The answer is 11
Step-by-step explanation:
Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:
B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
In this problem, the parameters are given as follows:

Hence, the bounds are given by:


The lower bound is below 0.5, hence option B is correct.
