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%
Answer:
answer below
Step-by-step explanation:
7)x greater than or equal to 15
8) x is less than 96
The ball describes a parabola, as you can see in the attached picture. So, the point where the ball strike the ground is the point where the parabola meets the x axis. In fact, the x-axis is the set of points where y=0, which means that the ball has height 0 or -again- it hits the ground.
So, we have to set y=0 in our equation and look for the positive solution. We have

And the positive solution is

So that's the distance from the child where the ball strikes the ground.
Answer:
it's $25.00
Step-by-step explanation:
Y= 4 (- x/3 + 1, 2x (-30))
