Here we MUST follow Order of Operations rules.
Must start out by doing the work inside the parentheses: (8+7) = 15
Next, multiply this result by 3: 3(15)=45 (answer)
You will have to work out the given versions of this problem until you find one that is also equal to 45.
All triangles must have angles that add up to the same amount of degrees, so if the two triangles share one exact point, it is assumed that those angles would be the same. Basically just use the fact that the sides are the same and marked by dashes, and the missing line can be proven with the use of the angles that are in between the point that both share.
Answer:
B)Margin of error becomes smaller
Step-by-step explanation:
given that you are conducting a poll to determine the percentage of adults who gamble at least once a month.
when sample size increases we find that n increases.
Standard error = std deviation / square root of n
Since standard error is inversely proportional to square root of n, we find that as n increases standard error decreases.
This results in reduction of margin of error.
So margin of error becomes smaller whenever sample size becomes larger
As a result confidence interval will get narrower.
B)Margin of error becomes smaller
2) The reason that you would select the option that you did above is due to what is known as _____inverse relation between n and margin of error.
