Answer:
OptionA
Step-by-step explanation:
95% confidence interval is obtained using the following formula
COnfidence interval lower bound = mean - critical value * sigma/sq rt n
and upper bound = mean + critical value*sigma/sq rt n
Thus margin of error = critical value*sigma/rt n
varies indirectly as n provided others are remaining the same.
Hence lower sample indicates higher margin of error
Out of 4 options given we find that I option has maximum margin of error as 21%
Hence option A is most likely coming from a small sample

So first we need to find how much is 5% of 300 , which we can discover by dividing 30p by 100 and multiplying by 5.
300÷100 ×5 = 15
So every year she pays $15 of interests
To find out how much she'll pay in 6 years pf interest , we just need to multiply 15 by 6
which is 90.
Then just add 90 to the original loan (300) to discover the total she will pay:
After 6 years, Ariane is charged $90 in interest. She pays a total amount of $390.
The answer is B. (2x + 5)(x + 1)You could answer this by expanding each answer until you found one that matched 2x^2 + 7x + 5, but I will only show how the answer expands:
2x × x = 2x^2
5 × x = 5x
2x × 1 = 2x
5 × 1 = 5
So in total those brackets expand to 2x^2 + 7x + 5. I hope this helps!
