Answer:
Step-by-step explanation:
Given
i.e. 10 people
Required
Probability of being next to each other
First, we calculate the total possible arrangements (without any restriction)
If the three are to be next to each other,
First, we arrange the three
Now, the 3 will be seen as 1; so, we have a total of 8 people i.e. (1 + 7 others)
The arrangement is:
So, the total arrangement, when they have to be next to one another is:
The probability is:
Expand
Express as percentage
Answer:
y=-(6/4)x
so if x=4 the equation will be
y=-(6/4) *-4
y=6
If 2 lines are parallel then:
they determine a plane, that is they are coplanar. In this plane, they never intersect.
<span>A) they intersect at a single point : Not True, they never intersect.
</span><span>B) they are perpendicular: Not true, they are parallel...
</span><span>C) the are skew lines : Not true, "skew" is the opposite of "coplanar". 2 lines are skew means that they are not on the same plane. But we mentioned that 2 parallel lines are always on the same plane.
</span><span>D) they are coplanar: True
Answer: D</span>
