Answer:

Step-by-step explanation:
The missing parameters are:
 --- population
 --- population
 --- population mean
 --- population mean
 -- population standard deviation
 -- population standard deviation
Required

First, calculate the sample standard deviation




Next, calculate the sample mean 

So:

So, we have:



Calculate the z score




So, we have:

From the z table

So:

 
        
             
        
        
        
The graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.
<h3>What is a graph?</h3>
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The curve of the function in the 2 quadrants is increasing when x tends to -∞ and in the quadrant, the curve f(x) is decreasing to -∞ as x tends to ∞.
Thus, the graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.

Answer:
22.5 in^2
Step-by-step explanation:
h = 3 in
base 1 = 6 in
base 2 = 9 in
So plug in
A = 1/2 (3) (6 + 9)
A = 3/2 (15)
A = 22.5 in^2
