The answer is r and s because it’s in the same plane.
Answer:
a) $49.48
b) $220921.91
Step-by-step explanation:
(a) 4 yd @ $12.37 per yd = 4 x $12.37 = $49.48
(b) 271 yd @ 815.21 per yd = 271 x $815.21 = $220921.91
(c) 20% yd @ $4.95 per yd : Here the nunber of yards are missing. Hence could not be answer . However if number of yards is x . The answer would be
20% of 4.95x
(20%=0.20)
0.20 × 4.95x
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.
