Answer:
1 / 2
Step-by-step explanation:
- 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
- Armed with the key observation, we see that the event that the last person's correct seat is free, is exactly the same as the event that the first person's seat was taken before the last person's seat.
- Well, each person had to make a random choice, was equally likely to choose the first person's seat or the last person's seat - the random chooser exhibits absolutely no preference towards a particular seat. This means that the probability that one seat is taken before the other must be 1/2
Answer: x = 3
First, you can multiply the 4 with the x and the 1:
4x + 4 + 8 = 24
Now, you just add the 4 and the 8 together:
4x + 12 = 24
Subtract 12 from both sides:
4x = 12
Now you divide by 4 from both sides
x = 3
^ and that's your final answer!
Answer:
Step-by-step explanation:
A) You are painting 5 faces, four sides and the bottom, of the pool because you are not painting the top of the pool.
B) You need 104 square meters to paint the pool.
Assuming the pool is a rectangular prism, use the surface area equation:
SA = wl + 2(hl) + 2(hw)
Note: Do not include times 2 for wl because we are only including the bottom of the pool.
l = 8 meters
w = 6 meters
h = 2 meters
SA = (6)(8) + 2((2)(8)) + 2((2)(6))
SA = 104 square meters
C) The paint with cost $624 total. $104 times 6 square meters equals $624
Slope = (2 + 3)/(4 +2) = 5/6
passing thru (4,2)
y = mx + b
2 = 5/6(4) + b
2 = 10/3 + b
b = 2 - 10/3
b = 6/3 - 10/3
b = -4/3

y = 5/6x - 4/3</span>
