I’m pretty sure it would be B
Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.
16 cm / 2cm = 8
8 x 8km = 64km total.
Dont mind but i just need to answer one question
Answer: b. The 99% interval is longer.
Step-by-step explanation:
The formula to find the confidence interval for mean :
, where is the sample mean , is the population standard deviation , n is the sample size and is the two-tailed test value for z.
For 95% confidence interval the two-tailed test value for z is .
For 99% confidence interval the two-tailed test value for z is .
Since the interval is directly proportion al to the z-value , so it is clear that the width of the interval would be longer with z =3 than z=2.
i.e. The <u>99% interval</u> is longer than 95% confidence interval .
The answer is 63/5ft long of the actual car. Hope this helps :)
