Answer:
The factorial of 11! is exactly 39916800
The number of trailing 0s in 11! is 2
The number of digits in 11 factorial is 8.
The factorial of 11 is calculated as below:
11! = 11 • 10 • 9 • 8 • 7 ... 3 • 2 • 1

Answer:

Step-by-step explanation:
                                                 Downtown Store   North Mall Store 
Sample size   n                             25                        20 
Sample mean  $9                        $8
                         $9                        $8 
Sample standard deviation  s       $2                        $1 




Standard error of difference of means = 
Standard error of difference of means = 
Standard error of difference of means = 
Degree of freedom = 
Degree of freedom = 
Degree of freedom =36
So, z value at 95% confidence interval and 36 degree of freedom = 2.0280
Confidence interval = 
Confidence interval = 
Confidence interval = 
Hence Option A is true 
Confidence interval is

Answer:
The answer is 35.5 square units
Step-by-step explanation:
The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner. 
We get this formula:
A(shape) = A(rectangle) - A(small triangle) + A(big triangle) 
SO LET'S FIND EACH!
A(rectangle)= length x width
length= 8 units
width= 4 units
We get:
A(rectangle) =8x4= 32 square unit
A(small triangle)= (base x height)/2
base= 1 unit 
height= 1 unit
We get: 
A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units
A(big triangle)= (base x height)/2
base= 2 units
height= 4units
We get: 
A(big triangle)= (2x4)/2 = 8/2 = 4 square units
For the final result:
A(shape) = 32 - 0.5 + 4 = 35.5 square units
