This is the definition of a rational number.
Answer:
There are 3,659,040 ways he can choose the books to put on the list.
Step-by-step explanation:
There are
12 novels
8 plays
12 nonfiction.
He wants to include
5 novels
4 plays
2 nonfiction
The order in which the novels, plays and nonfictions are chosen is not important. So we use the combinations formula to solve this problem.
is the number of different combinations of x objects from a set of n elements, given by the following formula.

How many ways can he choose the books to put on the list?
Novels:
5 from a set of 12. So

Plays:
4 from a set of 8. So

Nonfiction:
2 from a set of 12

Total:
Multiplication of novels, plays and nonfiction.

There are 3,659,040 ways he can choose the books to put on the list.
Answer:
Option: B is the correct option:
B. The point where the three medians of the triangle intersect
Step-by-step explanation:
We know that the centroid of a triangle is the point where the three medians of the triangle intersect.
<em>The centroid of a triangle is also known as the center of gravity of the triangle.</em>
The median of a triangle is a line segment that is drawn form a vertex of a triangle such that it meets the opposite site of the triangle at the mid-point.

The solution of the equation –3x + 1 + 10x = x + 4 will be 1/2. Then the correct option is A.
<h3>What is simplification?</h3>
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The equation is given below.
–3x + 1 + 10x = x + 4
On changing, we have
6x = 3
x = 1/2
Then the correct option is A.
