The answer is D. Maria selected a multiple that is not the least of the common multiples.
We see from the list that the least common multiple between 6 and 15 is 30, not 60.
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:
Given: X is midpoint of UV and Y is midpoint of VW.
(By mid-point theorem)

Answer:
The coordinates of the midpoint of the segment is (1,3.5)
Step-by-step explanation:
In this question, we are concerned with finding the coordinates of the mid point of the line that joins segment lb
To do this, we shall be using the midpoint formula;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
Where (x1,y1) = (8,5)
(x2,y2) = (-6,2)
Thus;
(x, y) = (8 + (-6))/2, (5 + 2)/2
(x ,y) = (2/2), (7/2)
(x,y) = (1,3.5)

C. It can make decision making more efficient.
