The value of the set operation A U ∅ is {3, 4, 5, 6}
<h3>How to evaluate the set operation?</h3>
The elements of the sets are given as:
U = {1, 2, 3, 4, 5, 6}
A = {3, 4, 5, 6}
To calculate the set A U ∅, we use the following illustration
A U ∅ = set A combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6} combined with an empty set
This gives
A U ∅ = {3, 4, 5, 6}
Hence, the value of the set operation A U ∅ is {3, 4, 5, 6}

Answer:
And the 90% confidence interval would be between [566.80 and 579.20]
Step-by-step explanation:
Information given
represent the sample mean
population mean (variable of interest)
s=22 represent the sample standard deviation
n=36 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.90 or 90%, the significance would be 
and 
, and the critical value for this case would be 
And replacing we got:
And the 90% confidence interval would be between [566.8033 and 579.1967]
I believe you would do the feet ,130, divided by the minutes ,35, to get how many feet per minute. It would get you a never ending decimal of 3.714285. So every minute he would drop about 4 feet. You will have to put it how it says to for what your answering is. If it says round to the whole number then he would drop 4 feet, but I hope this helps you in any way :)
