Answer:
(-3,14/3)
see below. You can use anything you like.
Step-by-step explanation:
5x+6y=13
I can sub any value for either x or y and then I try to solve for the other ones.
I am going to say x=-3
5(-3)+6y=13
-15+6y=13
6y=28
y=14/3
ordered pair=(x,y)
=(-3,14/3)
X=40
Y=30
Z=90

Answer:
Step-by-step explanation:
The probability of can be read as the probability of event B occurring given event A. In this question, event A occurs when the chosen player is a girl. There are 7 girls on the soccer team. Event B occurs when the chose player plays defense. Since stipulates that event A already occurred, we want the probability of choosing a player who prefers defense from the 7 girls. There are 2 girls who prefer defense, hence .
<u>Alternative:</u>
For dependent events and , the conditional probability of event B occurring given A is given by:
indicates the intersection of and . In this case, it is the probability that both events occur. Since there are 16 kids on the soccer team and only 2 are girls and prefer defense, . The probability of event A occurring (chosen player is a girl) is equal to the number of girls (7) divided by the number of kids on the team (16), hence .
Therefore, the probability of event B occurring, given event A occurred, is equal to:
I don’t know depends how much it is
