Solve. If there are X teams in a sports league and all the teams play each other twice, a total of N(x) gamers are played, where

N(x)=x^2-x. A soccer league has 10 teams, each of which plays the others twice. If the league pays $46 per game for the field and officials, how much will it cost to play the entire schedule?

Answer:

\$4140

Step-by-step explanation:

According to the problem, <em>x </em>refers to teams, and N(x)=x^{2}-x represents numbers of games played.

So, if there are 10 teams, we just have to replace this value for the <em>x</em> and calculate the number of games. Once we have it, we multiply all games by $46, which is the cost per game.

N(x)=x^{2} -x\\N(10)=(10)^{2}-10=100-10=90

This means that in the entire schedule there are 90 games. If each one costs $46, the whole schedule will cost:

90(\$46)=\$4140

The number of typing errors made by a typist has a Poisson distribution with an average of seven errors per page. If more than s
Aleks [24]

Answer:

0.599  is the probability that a randomly selected page does not need to be retyped.

Step-by-step explanation:

We are given the following in the question:

The number of typing errors made by a typist has a Poisson distribution.

\lambda  =7

The probability is given by:

P(X =k) = \displaystyle\frac{\lambda^k e^{-\lambda}}{k!}\\\\ \lambda \text{ is the mean of the distribution}

We have to find the probability that a  randomly selected page does not need to be retyped

P(less than or equal to 7 mistakes in a page)

P( x \leq 7) = P(x =1) + P(x=1) +...+ P(x=6) + P(x = 7)\\\\= \displaystyle\frac{7^0 e^{-7}}{0!} + \displaystyle\frac{7^1 e^{-7}}{1!} +...+ \displaystyle\frac{7^6 e^{-7}}{6!} + \displaystyle\frac{7^7 e^{-7}}{7!} \\\\= 0.59871\approx 0.599

Thus, 0.599  is the probability that a randomly selected page does not need to be retyped.
