Answer:
Step-by-step explanation:
When C=95,
      A = (100*95)/(4*3.14159) = 9500/3.14159 = 3023.94 sq. ft. 
 
        
             
        
        
        
The slope is the number with the letter x
The slope would be -10
The y intercept is the number at the end of the equation.
The y intercept is 1
 
        
                    
             
        
        
        
Answer:
C. 0
Step-by-step explanation:
 –4j^2 + 3j – 28 = 0
The discriminant is b^2-4ac  if >0 we have 2 real solutions
                                                    =0  we have 1 real solutions
                                                    <0 we have 2 imaginary solutions
a = -4, b =3  c = -28
b^2 -4ac
(3)^2 - 4(-4)*(-28)
9 - 16(28)
9 -448
This will be negative so we have two imaginary solutions.
Therefore we have 0 real solutions 
 
        
             
        
        
        
As in each table can seat 8 people and the probability you need to find is about the first person you can ignore this data.
Probability that the first person to enter the room will be randomly seated at a maple table:

#maple tables: 9
# total tables: 9 +10 +5 +7=31

Then, the probability that the first person to enter the room will be randomly seated at a maple table is 9/31
