P(boy) is asking for the probability that a boy will be chosen to read a poem out loud. Since there are 15 boys, we can get the probability by dividing this with the total number of students. This is because out of all the students, there is an equal possibility that each of the 15 boys will be chosen.
ANSWER: The probability that a boy is selected is 0.5357 or 53.57%
<span>y = –2x + 8
y = x – 4
We can use substitution.
-2x+8 = x-4
3x=12
x=12/3
x=4
</span>y = x – 4
<span>y=4-4=0
y=0
Solution of the system x=4,y=0,
it can be written as (4,0).
