Answer:
Step-by-step explanation:
Given
See attachment for model
Required
Determine 
from the model
The model is represented by:
To get: 
, 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
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 .
