Answer:
x=12, y=60
Step-by-step explanation:
Because the oppsite lines are parallel (you can tell because of the arrows) the opposite lines are the same length and the opposite angles are the same size.
This means y = 60 and x + 3 = 15 so x = 12
 
        
                    
             
        
        
        
Answer:
300
Step-by-step explanation:
To get from 120% to 100% you divide by 1.2  360/1.2=300 :)
 
        
             
        
        
        
First I will find the tip and then I will add that to the total and THEN I will add my sales tax to find 6% you have to multiply by 0.06.  to find 15% you have to multiply by 0.15
0.06 * 29.85 = 1.79
29.85 + 1.79 = 31.64
0.15 * 31.64 = 4.74
31.64 + 4.74 = $36.38
        
             
        
        
        
Answer:
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
Step-by-step explanation:
Here in this question, we want to state what will happen if the null hypothesis is true in a chi-square test. 
If the null hypothesis is true in a chi-square test, discrepancies between observed and expected frequencies will tend to be small enough to qualify as a common outcome.
This is because at a higher level of discrepancies, there will be a strong evidence against the null. This means that it will be rare to find discrepancies if null was true. 
In the question however, since the null is true, the discrepancies we will be expecting will thus be small and common.
