Answer:
75.
Step-by-step explanation:
If the mean is 75 miles per gallon and the standard deviation is of 10 miles per gallon, it means that most values will fall between 65 and 85 miles.
The percentile 50 falls in the middle of this range, therefore, the value that represents the 50th percentile will be:
(65 +85) / 2 = 150 / 2 = 75.

Answer:
Step-by-step explanation:
Average speed = total distance / total time taken
Average speed is the total distance traveled divided by the total time taken
The carrier first odometer route is
d_1 = 31,500 miles
On return of the truck, the odometer reads
d_2 = 31,713 miles
The total time taken is 6.5 hours on return
Then,
Average Speed = total distance / total time.
A.V = (d_1 + d_2) / t
A.V = (31,500 + 31713) / 6.5
A.V = 63213 / 6.5
A.V = 9725.1 mile per hour
A.V = 9725.1 mph
