Answer:
1st option
Step-by-step explanation:
Given the 2 equations
2x + 5y = 19 → (1)
y = 3x - 3 → (2)
Substitute y = 3x - 3 into (1)
2x + 5(3x - 3) = 19

The solution would be like this for this specific problem:
 

 
 

 
The correct sequence of operations when solving
negative one over five (x − 25) = 7 would be multiply each side by −5, and adding
25 to each side.
 
        
             
        
        
        
Answer:  False
Step-by-step explanation:
We know that , If p-value <  , we reject the null hypothesis .
 , we reject the null hypothesis .
 If p-value ≥  , we are fail to reject the null hypothesis .
 , we are fail to reject the null hypothesis .
As per given , we have
The p value for an independent samples t-test is 0.043.
The level of significance is  
 
Since , 0.043 < 0.05.
i.e. p-value <   
 
It means  we reject the null hypothesis .
It means the null hypothesis is false.
Hence , the correct decision in this scenario is to favor the null hypothesis : False
