prisoha [69]

You have $15 and admission is $5, so you know have $10 before doing any games. If you wanted to play 12 games, you would need $10.20, which you do not have. But, if you wanted to play 11 games, then you would need $9.35, which is just under $10.

So the maximum amount of games that you could play would be 11 games.

A club volleyball league allows only the top 5% of athletes who try out to be part of the team. If the team tryout scorecard has

lapo4ka [179]

Answer:

Among the given options, the one which can be used as a minimum qualifying score to join the volleyball league is, 274.

Step-by-step explanation:

Let the team tryout scorecard is represented by the random variable X.

Now, according to the question,

X $\sim$ Normal (250 , 15)

Let Z = $\frac {(X - 250)}{15}$ -----------------------(1)

So, Z $\sim$ Normal (0, 1)

According to the question, the bottom 95% in the tryout scorecard are to be eliminated.

Let, P(Z ≤ $z_{0.95}$ ) = 0.95

Now, from the inverse standard normal probability table,

$z_{0.95}$ = 1.645

So, if we say that

P(X ≤ $x_{0.95}$ ) = 0.95, then

$x_{0.95} = z_{0.95} \times 15 + 250$ --------------[from (1)]

= $1.645 \times 15 + 250$

= 274. 675

Hence, from the given options, the answer is, 274.
