There are 19 people total, and groups of four are being asked of us. We can use the formula for permutations or combinations.
Permutations:
Combinations:
Where in both scenarios, there are <em>n</em> objects being chosen at <em>r</em> times.
19 P 4 is 93024
19 C 4 is 3876
It all depends on whether order matters with group placement; if it does, your answer is
93024, if not, then your answer is
3876.:)
To solve the equation:
63+54+98x83+1222-3000+9
=63+54+1222+9+(98×83)-3000
=1348+8134-3000
=9482-3000
=6482
The answer is 6482.
Hope it helps!
Answer:
47
Step-by-step explanation:
divide 1200 by 25 and u get 47 so we have 1 nickel to add the 5 cents.
Answer:
25. Yes, it is a function, because none of the x outputs are repeating
Answer:
(3,1) and (3,2)
Step-by-step explanation:
We are given that a relation
{(0,0.5),(0.5,1),(3,1),(1,6),(3,2)}
We have to find that ordered pair which causes this relation not to be a function.
We know that
Function: It is a mapping between two non- empty set A and B.
Every element of set A has unique image in set B.
One element of set A can not have two or more images in set B.
Two or more elements of set A have same images in set B.
In given relation images of 3 are 1 and 2 which is not possible if a relation is function because one element can not have two or more images.
The ordered pair (3,2) and (3,1) cause this relation not to be a function because image of 3 are 1 and 2 which is not possible .
Answer: (3,1) and (3,2)
