Answer:
0.8
Step-by-step explanation:
In this question you need to translate a fraction into a decimal.
Firstly you must focus on discovering the digit that you divide 100 by to get 5
100 / 5 = 20
Next, you must multiply both the denominator and multiplier by 20
4 x 20 = 80
5 x 20 = 100
This is 80%
We can then divide 80 by 100 to give us 0.8
(x,y)=(64/81, 70/81) I can provide a description if needed. I used the process of elimination.

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.:)
