Step-by-step explanation:
ANSWER. 77 adults; 2*77 = 154 children and the rest (315-77-154) = 84 students.
The width of the walkaway be 4 feet.
<h3>What is Discriminant Formula?</h3>
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation
is D =
If D > 0, then the equation has two real distinct roots.
If D = 0, then the equation has only one real root.
Given that: 
also, area of walkaway = 464 square feet.
So, 

Using Discriminant method,
a=4, b=100, c=-464

w= 
w= 
So, 


Hence the width of the walkaway be 4 feet.

Answer:
This may not be that accurate as I am a bit rusty with trigonometry:
tan D: d/f
sin F: f/e
tan F: f/d
cos F: d/e
sin D: d/e
cos D: f/e
Answer:
7(tan50°)
Step-by-step explanation:

The probability that a randomly selected customer takes more than 10 minutes will be 8.38%
<em><u>Explanation</u></em>
The average or mean
is 8.56 minutes and standard deviation
is 1.04 minutes.
<u>Formula for finding the z-score</u> is: 
So, the z-score for
10 minutes will be.....

Now, according to the standard normal distribution table,
. So.....

So, the probability that a randomly selected customer takes more than 10 minutes will be 8.38%
