The function "choose k from n", nCk, is defined as
nCk = n!/(k!*(n-k)!) . . . . . where "!" indicates the factorial
a) No position sensitivity.
The number of possibilities is the number of ways you can choose 5 players from a roster of 12.
12C5 = 12*11*10*9*8/(5*4*3*2*1) = 792
You can put 792 different teams on the floor.
b) 1 of 2 centers, 2 of 5 guards, 2 of 5 forwards.
The number of possibilities is the product of the number of ways, for each position, you can choose the required number of players from those capable of playing the position.
(2C1)*(5C2)*(5C2) = 2*10*10 = 200
You can put 200 different teams on the floor.
Answer:
The answer depends on what the problem really is.
f(1/2) = 8
or
f(1/2) = 4
See below.
Step-by-step explanation:
This is the problem as it was posted:
y = f(x) = 16x
Let x = 1/2
y = f(1/2) = 16(1/2) = 8
Perhaps the problem is this:
If x is an exponent of 16 and not a factor, then the answer is:

Answer:</h2><h2>18</h2><h2 /><h2>Hope this helps!!</h2>
(2n/6n+4)(3n+2/3n-2)
=2n(3n+2)/(6n+4)(3n-2)
=(6n^2 + 4n)/(18n^2 - 12n + 12n -8)
=(6n^2 + 4n)/(18n^2 - 8)
=2(3n^2 + 2n)/2(9n^2 - 4)
=(3n^2 + 2n)/(9n^2 - 4)
=n(3n+ 2)/(3^2 × n^2 - 2^2)
=n(3n+ 2)/(3n-2)(3n+2)
=n/(3n-2)
Answer:The numerator of the simplified expressions is n.
X= entire test
if
18=.9x
then divide both sides by .9
18/ .9
and x = 20
20 questions total on the test
