Answer:
43,758 different swimmer squad
Step-by-step explanation:
Given;
Total Number of athletes n = 18
Number of athletes needed to be selected r = 8
For this case, the coach need to select 8 players from a total of 18 athletes with no particular order. So, this is a combination case since the order of selection is not relevant.
The number of different swimmer squads the coach could select is;
S = nCr
nCr = n!/(r!×(n-r)!)
Substituting the values of n and r;
S = 18C8
S = 18!÷(8! × (18-8)!)
S = 18! ÷ (8!×10!)
S = 43,758
Therefore, he can select 43,758 possible different squads
Answer:
This is equation of ellipse
Step-by-step explanation:
we are given
We can see that right side is 36
so, we can make right side as 1 by dividing both sides by 36
we can simplify it
we can rewrite it as
now, we can compare it with standard equation of ellipse
we can see that both equations are similar
so, this is equation of ellipse
