Answer: 40000
Step-by-step explanation:
The formula to find the sample size is given by :-
, where p is the prior estimate of the population proportion.
Here we can see that the sample size is inversely proportion withe square of margin of error.
i.e. 
By the equation inverse variation, we have

Given :


Then, we have

Hence, the sample size will now have to be 4000.
180-130=50
180-96=84
angles in a triangle add up to 180
50+84=134
180-134=46
x=46 degrees
Find answer is the given attachment
The answer is -88
When you multiply and then divide
Answer:
-50+9x
Step-by-step explanation:
multiply the numbers -49+9x -1
calculate the difference(-49-1 -50 + 9x
