Answer:
with these characteristics, place the
semi-ellipse on coordinate axes in a convenient position and draw it.
5. What is the equation of the ellipse? How wide will the canal need to be for the
Petroleum ship?
6. Now that you know which of the two alternatives provides the widest channel, consider other
factors. His department is also in charge of verifying the depth of the channel, the
amount of river traffic and other details. For example, if there was a flood in the river and
the water level will rise 10 feet, how would free space be affected? Take a decision
about which project you think would be best as far as your department is concerned and

Answer:
5=35
Step-by-step explanation:
Answer:
The sample proportion 
is within 0.03 of the true proportion of customers who are under age 21 is 0.803
Step-by-step explanation:
Total no. of customers = n = 400
We are given that the true population proportion of customers under age 21 is 0.68.
So, p =0.68
q=1-p=1-0.68=0.32
Standard deviation =
We are supposed to find the probability that the sample proportion is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that is between 0.68 - 0.03 and 0.68+ 0.03
Using Z table
Hence the sample proportion is within 0.03 of the true proportion of customers who are under age 21 is 0.803
