Answer:

Step-by-step explanation:
Given
See attachment for model
Required
Determine  from the model
 from the model
The model is represented by:

To get:  , we consider the first partition
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 36 ---- this represents the numerator
So, we have:

To get:  , we consider the first partition
, we consider the first partition
The number of shaded box is 63 ---- this represents the denominator
The total boxes shaded at the bottom is 16 (do not count the gray boxes) ---- this represents the numerator
So, we have:

The equation becomes:




 
        
             
        
        
        
Lets first numbers is x, second is (x+2), third is x+4
sum is x+(x+2)+(x+4)=87
3x+6=87
3x=81
x=27
Answer: smallest number is 27
        
                    
             
        
        
        
The equation has no X variable so whatever that adds up to becomes the y-intercept. 
- 2/9 + 1/5 >> - 10/45 + 9/45 = - 1/45 
Your y-int is - 1/45 or (0, - 1/45)

Answer:
Option A is correct 
Step-by-step explanation:
From the question we are told that  
   The  95% confidence interval of the mean  score of all  New Jersey third graders  is  (58.957 ,  63.043)
    The sample size is  n =  184
    The sample average is  
    The standard deviation is   
     The  90%  confidence interval for the difference in mean score between lowa and New Jersey is  (-6.33 ,  -1.67 )
    The  p-value is  
Generally given that the p-values is very low compared to the level of significance (100 -90 =  10% = 0.10 )  we can reject the null hypothesis which is usually a  claim that the means of the  population are the same ) 
Hence the population means are different .
