Step-by-step explanation:
This is a classic puzzle!
The answer is that the probability that the last person ends in up in his proper seat is exactly
1
2
The reasoning goes as follows:
First observe that the fate of the last person is determined the moment either the first or the last seat is selected! This is because the last person will either get the first seat or the last seat. Any other seat will necessarily be taken by the time the last guy gets to 'choose'.
Since at each choice step, the first or last is equally probable to be taken, the last person will get either the first or last with equal probability:

Answer:
The speed is:
5 meters per second
In then seconds: 50 meters
Step-by-step explanation:
1 hour = 3600 seconds
1 km = 1000 meters
18km = 18*1000 = 18000 meters
then:
18km/h = 18000m/3600sec = 5m/s
The speed is:
5 meters per second
proportions:
5 meters ⇔ 1 second
W meters ⇔ 10 seconds
W = 5*10/1
W = 50 meters

Let's split these two situations up.
Linda
Linda deposits $1,800 into an account that pays 7.5% interest, compounded.
The equation:
1,800× 1.075^x=y
Let's put in 10 for x.
1.075^10= 2.06103156 × 1,800= 3,709.85681≈ 3,710
Anna
Anna deposits $4,000 into an account that pays 5% interest, compounded.
The equation:
4,000× 1.05^x=y
Let's put in 10 for x.
1.05×10= 1.62889463×4,000= 6515.57852= 6516
A) Linda's account: $3,710
Anna's account: $6,516
