Complete Question

1. (12 points) The tennis team at Taft High School has 8 players, and the tennis team at McKinley High School has 7 players. Rebecca is on the team at Taft, and her sister Leah is on the team at McKinley. The two teams are going to play a tournament with 4 rounds. In each round, one player from Taft will play a match against one player from McKinley. Each player can play in at most one match. A schedule for the tournament consists of an ordered list of the names of the players from each school who will play in each of the four rounds. The schedule does not include the results of each match.

(a) How many schedules are there?

(b) How many schedules include neither sister?

Answer:

a

   N  =  1,411,200

b

  M  =  302, 400

Step-by-step explanation:

From the question we are told that

   The  number of players in Taft High School is t =  8

    The  number of players in McKinley High School  is k = 7

   The number of rounds is  n  =  4

   The highest number of match each player can play is  w =  1

   

Generally the total number of schedules is  

      N  = ^tP_4 * ^k P_4

      N  = ^8P_4 * ^7 P_4

=>   N  =  \frac{8!}{(8-4)!} * \frac{7!}{(7-4)!}

=>   N  =  \frac{8!}{4!} * \frac{7!}{3!}

=>  N  =  \frac{8*7 *6*5*4*3*2*1}{4*3*2*1} * \frac{7*6*5*4*3*2*1}{3*2*1}

=>  N  =  1,411,200

Generally the  number of schedules that include neither of the sisters is  mathematically represented as

        M= \ ^{t-1}P_4 *\ ^ {k-1} P_4

        M= \ ^{8-1}P_4 *\ ^ {7-1} P_4

=>    M= \ ^{7}P_4 *\ ^ {6} P_4

=>     M  =  \frac{7!}{(7-4)!} * \frac{6!}{(6-4)!}

=>     M  =  \frac{7!}{3!} * \frac{6!}{2!}

=>     M  =  \frac{7 *6*5*4*3*2*1}{3*2*1} * \frac{6*5*4*3*2*1}{2*1}

=>      M  =  302, 400

On a 50-question test, a student answered 5 questions incorrectly. What percent did the student answer correctly? A. 55% B. 45%
vodomira [7]
Total number of questions = 50
Number of questions answered incorrectly = 5
Therefore,
Number of questions answered correctly = 50-5 = 45 questions

Now, to get the percentage of correct answers, we will divide the number of correct answers by the total number of questions and then multiply the quotient by 100 as follows:
% of correct answers = (45/50) * 100 = 90%

Comparing the calculated value to the choices we have, we will find that the correct choice is:
D. 90%
