Trava [24]
36.75 \leq p \leq 98
t(p)= \frac{p}{12.25}
\\t(36.75)= \frac{36.75}{12.25} =3
\\t(98)= \frac{98}{12.25} =8
\\3 \leq t(p) \leq 8

64 teams participate in a softball tournament in which half the teams are eliminated after each round of play.
notka56 [123]

Answer:

After 6 rounds one team will win.

Step-by-step explanation:

This is an example of geometric progression,

Let p(n) represents the number of participants remaining after n rounds of play.

First term = 64

\texttt{Common ratio = }\frac{1}{2}

We have

               p(n)=a\times r^{n}\\\\p(n)=64\times \left (\frac{1}{2} \right )^{n}=2^{6}\times \left (\frac{1}{2} \right )^{n}\\\\p(n)=2^{6-n}

Number of teams remaining after n rounds of play, p(n) = 2⁶⁻ⁿ

Here we need to find for what n p(n)=1

           2^{6-n}=1\\\\2^{6-n}=2^0\\\\6-n=0\\\\n=6

After 6 rounds one team will win.
