Answer:
The mean will reduce
Step-by-step explanation:
The total amount of money for the ten days divided by number of days will give mean 1, M₁
Removing the value for day seven will reduce the sum of money as it will be for 9 days only.In finding the mean, you will divide by 9 days to get mean M₂
Mean M₂ < M₁
Calculate total distance
distance = speed * time
= 480 * 9
=4320MILES
therefore trip to Las Vegas
time = distance/ speed
=4320/ 432
= 10hours
