Number of students = 26
Number of students without siblings = 4
⇒ Number of students with at least one siblings = 26 - 4 = 22
Number of students with brothers = 17
Number of students with sisters = 7
⇒ Number of students with both a brother and a sister = 17 + 7 - 22 = 2
P(student has a brother, given that they have a sister) = 2/7
Answer: 2/7
You would plug in the values of each x.
Making, f(12) be 47, f(-4) be 7, and f(0) be 17
I did .3 x 255 and that gave me 30% of 255 which is 76.5

They spent 6 hours white water rafting.
$50x5=250
$250- $1000=$750
