Just add the angles up.
OptionAStep-by-step explanation:95% confidence interval is obtained using the following formulaCOnfidence interval lower bound = mean - critical value * sigma/sq rt nand upper bound = mean + critical value*sigma/sq rt nThus margin of error = critical value*sigma/rt nvaries indirectly as n provided others are remaining the same.Hence lower sample indicates higher margin of errorOut of 4 options given we find that 1 option has maximum margin of error as 21%Hence option. A is most likely coming from a small sample.
Answer:
n = 24 - 8.
Step-by-step explanation:
n + 8 = 24
Subtract 8 from each side:
n + 8 - 8 = 24 - 8
n = 24 - 8.
The factor is (x+6)(x+6)
So, D. x+6 is the correct answer :)
I think it is A
sorry if it is wrong!
