Answer:
The maximum speed of Hal's airplane in still air is:

The speed of the wind

Step-by-step explanation:
Remember that the velocity v equals the distance d between time t.
and 
The distance that Hal travels when traveling with the wind is:
miles
Where v is the speed of Hal and c is the wind speed.
The distance when traveling against the wind is:
miles
Now we solve the first equation for v




Now we substitute the value of v in the second equation and solve for c







Then:


The maximum speed of Hal's airplane in still air is:

The speed of the wind

Answer:
24 cubic inches
Step-by-step explanation:
The formulas for the volume of a cylinder and cone are ...
volume of a cylinder = πr^2·h
volume of a cone = (1/3)πr^2·h
For the same radius and height, the cone has 1/3 the volume of the cylinder. Your cone's volume is ...
(1/3)·(72 cubic inches) = 24 cubic inches
The sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.
<h3>What are population and sample?</h3>
It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.
We have:
A sample has a sample proportion of 0.3.
Level of confidence = 95%
At the same confidence level, the larger the sample size, the narrower the confidence interval.
As we have a 95% confidence interval the sample size should be lower.
The sample size from the option = 36 (lower value)
Thus, the sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.
