5 hours 20 minutes
Step-by-step explanation:
Distance traveled to be 20 miles apart
180 - 20 = 160 miles

14 + 16 = 30 mph
time = distance / speed
t = 160/30
t = 5 1/3 hours
t = 5 hours 20 minutes

Answer:
1. About 68% of the data lie within one standard deviation of the mean.
2. About 95% of the data lie within two standard deviation of the mean.
3. About 99,7% of the data lie within three standard deviation of the mean.
Step-by-step explanation:
1. 34 + 34 = 68
2. 68 + 13,5 + 13,5 = 95
3. 95 + 2,35 + 2,35 = 99,7
Answer:
√(r+n)/5=m
Step-by-step explanation:

r+n=5m²-n+n
r+n/5=m²
taking square root on both sides
√(r+n)/5=m
