Since the ball starts out on the ground before being kicked x=0. find the corresponding value for y, in feet.

Considering an example of football :-

When we kick the ball, it goes through a parabolic path whose equation is given by :-

y = ax² + bx + c

where 'c' is the y-intercept of parabolic curve on coordinate plane.

Depending upon the initial conditions, the value of c varies.

It says the ball starts out on the ground before being kicked, it means y-intercept is on ground i.e. c = 0.

Now the equation would become :- y = ax² + bx.

It says to find corresponding value of y when x=0.

Plugging x=0 in the above equation :-

y = a(0)² + b(0)

y = 0

So, final answer is y = 0.

There are 7 green aprons and they are to be assigned randomly to twenty five volunteers. Therefore, the probability of being assigned a green apron is:

Thus, the the probability that a volunteer is assigned an apron that is NOT green is a complementary event and is thus given by:

Therefore, in terms of percentage, the odds of not getting a green apron is 72%.
