Answer:
(2) 4, 7, 9; 2, 5, 6; 1, 3, 8
Step-by-step explanation:
Let's group them based on how many lines they have inside the shape...
0 lines: 4, 7, 9
2 lines: 2, 5, 6
3 lines: 1, 3, 8
Therefore the answer is (2) 4, 7, 9; 2, 5, 6; 1, 3, 8
 
        
             
        
        
        
X = Amount paid one hour
205.25 - 59 = 146.25
3.25x = 146.25
x = 146.25 ÷ 3.25
x= 45
        
             
        
        
        
Answer:
Probability that next week's show will have between 30 and 37 million viewers is 0.2248.
Step-by-step explanation:
We are given that the distribution of the number of viewers for the American Idol television show follows a normal distribution with a mean of 26 million with a standard deviation of 8 million.
<em>Let X = number of viewers for the American Idol television show</em>
So, X ~ N( )
)
Now, the z score probability distribution is given by;
           Z =  ~ N(0,1)
 ~ N(0,1)
where,  = population mean = 26 million
 = population mean = 26 million
              = standard deviation = 8 million
 = standard deviation = 8 million
So, probability that next week's show will have between 30 and 37 million viewers is given by = P(30 < X < 37) = P(X < 37) - P(X  30)
 30)
     P(X < 37) = P(  <
 <  ) = P(Z < 1.38) = 0.91621
 ) = P(Z < 1.38) = 0.91621
     P(X  30) = P(
 30) = P(  
  
  ) = P(Z
 ) = P(Z  0.50) = 0.69146
 0.50) = 0.69146
<em>Therefore, P(30 < X < 37) = 0.91621 - 0.69146 = 0.2248</em>
Hence, probability that next week's show will have between 30 and 37 million viewers is 0.2248.
