Step-by-step explanation:
We are dealing with theoretical probability. This means that our probability of said outcome is

where x is the outcome we want, and y is the total number of outcomes possible. 
28. There is 3 triangles out of 6 polygons so the probability is 1/2.
29.There is 1 Pentagon so the probability is 1/6.
30. This is a complement to question 28. A complement is the inverse of the problem. A complement and its original add to 1 so the probability of both getting a triangle is 1/2. 
31. There is 4 non quadraletrial so the probability is 2/3.
32. There is 3 figures that has more sides than three so 1/2 is the probability.
33.There is only multi right angles figures so 1/2 is the probability.
34. There is 30 days in April so the probability it's the 29th is

35. There is 31 days in July and 15 days after the 16th. So the probability
is

 
        
             
        
        
        
Answer:
4x is the greatest common factor of those two.
Step-by-step explanation:
(-16x + 12x)
4x (-4 + 3)
4x is the GCF 
Why you may ask is 4x the GCF because when you divide 4x from both you're left with -4 + 3...... you can't take out the negative from the 16 because when you check your work negative 4x times 3 gives you negative 12x which isn't the equation you started with. So positive 4x times 3 give you 12x.
Hopes this helps!!!
 
        
             
        
        
        
Answer:
$966
Step-by-step explanation:
6/7 =  828/x
Write a proportion.
6x =	7(828)	Use cross products.
6x =	5796	Multiply.
x =	966	Divide both sides by 6.
Paul's investment was $966.
