There are 18 + 12 total students.
18 are girls and 12 are boys, since the total is 30 students, that's the amount of probable outcomes, and since there are 12 boys, that's the amount of favorable outcomes, thus
12/30 or 0.4, 0.4 * 100 is 40%.
Answer:
3+18=21
Step-by-step explanation:

Answer:
52 miles per hour
Step-by-step explanation:
Firstly, It is important to point out that it is Average speed. The Average speed throughout all the way the car traveled.
And this is may calculated by a simple formula or if you'd rather by a proportion. Let's pick this simple formula, what's going to be useful.
Let's do the math!
Average speed = Δs/Δt
Δs = Variation of Space (given in miles) =156 -0
Δt =Variation of Time (given in hours) =3-0
Average Speed = 156-0/3-0 =156/3 =52 miles per hour
It is important to say, Average speed, is a rate so it is given in miles per hour
