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:
1
2

Step-by-step explanation:
18(2+x) because 18*2=36 and 18*x=18x
Answer:
-3/1
Step-by-step explanation:
The slope can be found by putting the rise over the run.
Pick 2 points on the graph that intercept the line.
I'll pick (0,2), and (1,-1)
Look at the rise.(How many places it goes up or down)
The rise vertical distance(rise), between the two points is -3.
Now look at the run(the horizontal distance.) It's 1.
Rise/Run = -3/1 AKA -3
1. (5x - 2) + 7x = 12x - 2
2. 6(x - 5) > 22
6x - 30 > 22
6x > 52
x > 52/6
x > 26/3
