Answer:
The sum of all the possible values for z that satisfy the above equation is -5.
Step-by-step explanation:
The given equation is

We need to find the sum of all the possible values for z that satisfy the above equation.
The given equation can be rewritten as

Cancel out common factors.

Add 2 on both sides.



Multiply both sides by -1.

Only z=-5 satisfy the given equation.
Therefore the sum of all the possible values for z that satisfy the above equation is -5.
 
        
             
        
        
        
Answer:

Correct answer: A) A = the card is red, B = the card is black
Because mutually exclusive means "cannot occur simultaneously."
The other choices all can occur together.
        
             
        
        
        
Answer:
14.13 ft²
Step-by-step explanation:
The area of a semicircle is 

We were given the radius of the semicircle to be: r=3 feet.
We were also asked to use π as 3.14.
We substitute into the formula to get:

This is the same as:

Or


The area of the semicircle is 14.13 ft²
