According to the information, it can be inferred that the volume of the ice cream is close to 207.33 cm³
<h3>How to calculate the volume of the maxicool?</h3>To calculate the volume of the maxicool, we must calculate the volume of the sphere of ice cream, and the volume of the cone that is filled with ice cream.
<h3>Volumen of the sphere</h3>V = × π × R³
V = × π × 3³
V = 113.09 cm³
<h3>Cone volume</h3>
V = × π × R² × <em>h</em>
V = × π × 3² × 10
V= 94.24 cm³
Finally we must add both values to know the total volume of the maxicool.
113.09 + 94.24 = 207.33 cm³

Answer:
99.7% confidence interval is
Step-by-step explanation:
The formula for a confidence interval for a population proportion is where
is the sample proportion,
is the sample size, and
is the critical score for the desired confidence level.
We are given a sample size of and a sample proportion of
. Our critical score for a 99.7% confidence level would be
Therefore, the approximate 99.7% confidence interval for the population parameter is
So we are 99.7% confident that the true population proportion is contained within the interval
