The values of x and y are 8 and 10, respectively
<h3>How to determine the values of x and y?</h3>
The list of the numbers is given as:
4, 7, x, y, 11
The mean and median of the five numbers are the same.
The median is the middle number.
So, we have
Median = x
This means that
Mean = Median = x
The mean is calculated as:
Mean = Sum/Count
This gives
(4+ 7+ x+ y+ 11)/5 = x
Evaluate the sum
(22 + x + y)/5 = x
This gives
22 + x + y = 5x
Evaluate the like terms
4x = 22 + y
Based on the order of the list, we have:
7 < x < y < 11
Assume y = 10
4x = 22 + 10
This gives
x = 32/4
x = 8
Recall that:
7 < x < y < 11
This means that
7 < 8 < 10 < 11
The above is true
Hence, the values of x and y are 8 and 10, respectively

Step-by-step explanation:
Answer:
see the explanation
Step-by-step explanation:
we know that
The<u><em> Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Applying the triangle inequality theorem
Let
c ----> the measure of the length of the third side
1) 
2) 
so
The solution for the length of the third side is the interval (2,22)
All real numbers greater than 2 centimeters and less than 22 centimeters
$1.98 divided by 2 is $0.99
So the sale price is $0.99
