Step-by-step explanation:
Divide the percentage by 100. E.g 74%=64/100
Then simplify the newly made fraction,
Find the common factors,
E.g 64/100
Both can be divided by 2
32\50
Repeat simplifying step...
16\25
Till there are no more common factors
and that's the final answer...

They are equal. They're equal because if you simplify 500/600, it becomes 5/6.
Answer: C. 461
Step-by-step explanation:
We know that the formula to find the sample size is given by :-
, where = Population standard deviation from prior study.
E = margin of error.
z* = Critical value.
As per given , we have
E= 15
Significance level :
Critical value (Two tailed)=
Now , Required sample size =
[Round to next integer]
Hence, the required sample size to be taken is 461.
Correct answer = C. 461
Any kind of Triangle must have 180 degree of angle in total if it is not, then it is not a Triangle.
In short, Your Answer would be Zero
Hope this helps!
