A class has 12 girls and 18 boys. What is the probability that a boy raises his hand and asks to go to the bathroom given a girl already left the room to go to the bathroom?

The answer is  

Explanation:-

Total number of students = 12 + 18 = 30

Total number of students after one girl left = 29

Number of boys = 18

Probability that a boy raises his hand and asks to go to the bathroom =

Number of boys divided by total number of students

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
