In one round robin chess tournament, 36 games were played. How many players entered in the tournament?
ICE Princess25 [194]
\displaystyle
\binom{n}{2}=36\\\\
\dfrac{n!}{2!(n-2)!}=36\\
\dfrac{n(n-1)}{2}=36\\
n(n-1)=72\\
n^2-n-72=0\\
n^2-9n+8n-72=0\\
n(n-9)+8(n-9)=0\\
(n+8)(n-9)=0\\
n=-8 \vee n=9

The number of players can't be negative, so there was 9 players.

(vii) log32 8=m<br> Again please
KonstantinChe [14]

Answer:

log_(32)8= 3/5

Step-by-step explanation:

Log_(32)8 = m

write is as

32^m=8

(2^5)^m = 2^3

2^5m = 2^3

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

5m = 3

divide 5 on both sides to remove it from m

m= 3/5

Hope this helps!

Step-by-step explanation:

This is a combination problem where we have to select two member out of 7 members

 

So we want calculation of  7C2

 

   7C2 = 7!/[(2!)(7-2)!]

   (7*6*5*4*3*2*1)/[(2*1) *(5*4*3*2*1]

   (7*6)/2    ~  Note everything that easily cancels here!

   42/2
