<h3>
Answer:  x = 29</h3>
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29
------------
Explanation:
- The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
- In the second step, I subtracted 61 from both sides to undo the "+61".
 
        
        
        
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.
