B = 2 + g . . . (1)
g = 6 + r . . . (2)
r = 6 + p . . . (3)
Putting (3) into (2) gives:
g = 6 + 6 + p = 12 + p . . . (4)
Putting (4) into (1) gives:
b = 2 + 12 + p = 14 + p . . . (5)
b + g + r + p = 1200
2 + g + 6 + r + 6 + p + p = 1200
2 + 12 + p + 6 + 6 + p + 6 + p + p = 1200
32 + 4p = 1200
4p = 1200 - 32 = 1168
p = 292
From (5), b = 14 + p = 14 + 292 = 306
Therefore, there are 306 blue mables.
        
             
        
        
        
Answer:
B: (x + 2)(x - 3)^2
Step-by-step explanation:
This is only going to have 3 roots. One of them is (x - 3) 
D does not look right. So let's solve it using synthetic division.
3 || 1    - 4      -3       18
             3       -3      -18
========================
      1     -1       -6        0
So what you have is a quadratic
- x^2 - x - 6 = 0 which will factor
- (x - 3)(x + 2) = 0
- x - 3  = 0
- x = 3
- x + 2 =0
- x = - 2
- (x - 3)(x - 3)(x + 2 ) = 0
The answer is B
 
        
             
        
        
        
Answer:
C. The president rejects the hypothesis that the proportion of students who earn a bachelor's degree within six years is 0.398, when, in fact, the proportion is 0.398. 
Step-by-step explanation:
A type I error occurs if you reject the null hypothesis when it is true.
Now the hypotheses are:

 The proportion is 0.398

 The proportion is less than 0.398
If in actual fact the proportion is 0.398, then the president must not reject the 

.
This is a correct decision.
If in actual fact the proportion is 0.398, and the president rejects the 

, then a type I error is committed.
The correct choice is C.
 
        
        
        
Answer:
no solution
Step-by-step explanation:
if you subtract the equations then you get 0 = 8 and this can never be true; therefore there are no solution
