Answer:
A. 1, 287 ways
B. 154,440 ways
Step-by-step explanation:
A. We want to choose 5 objects from a total 13, without considering the order in which they are chosen.
The correct way to do this is by using the combination formula since order is not considered;
Thus we have ; 13 C 5 read as 13 combination 5;
Mathematically, n C r is ; n!/(n-r)!r!
Thus, we have ;
13!/(13-8)!8! = 13!/5!8! = 1,287 ways
B. By considering order, we shall be using the permutation formula;
Mathematically n P r = n!/(n-r)!
Read as n permutation r;
Using the numbers involved, we have ; 13 P 5
= 13!/(13-5)! = 13!/8! = 154,440 ways
Answer:

Step-by-step explanation:
<em>See Attachment for complete question</em>
For this question, we only need the data at the Congtin column.
So, we have:


First, we need to reduce Giraffe by 63%.
This gives:




Represent this as a ratio:

The closest to this ratio is 3:7.
This is shown by dividing the ratio by 15
i.e.


Approximate:

Answer:
Suppose there are 1,000 candies in a jar. There are 50 children in a room. If i want to share 1000 candies among all the children. How can i divide 1,000 candies equally in 50 children.
Step-by-step explanation:
Create a story line(word problem) means to create a fake or real story by translating an algebraic expression in english.
We can create a story by the given 1,000/r:
Suppose there are 1,000 candies in a jar. There are 50 children in a room. If i want to share 1000 candies among all the children. How can i divide 1,000 candies equally in 50 children.
Here r = 50....
Answer:
12
Step-by-step explanation:
610 divided by 55 = 11.09
but since u cant have 11.09, u need 12
A point and a line.
<h3>Further explanation
</h3>
Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g.,
.
The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.
Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.
These key terms cannot be mathematically defined using other known words.
- A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
- A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
- A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
