The number of horses occupying stalls at the county fairgrounds can be modeled by the following function, where x represents the number of days since the first of June. h(x) = -3x^2 + 30x + 225
a h(x) = -3(x + 5)( x - 15)
b h(x) = -3(x + 5)( x - 15)
c h(x) = -3(x - 2)( x - 15)
d h(x) = -3(x + 2)( x - 15)
A HONESTL screw it heres free points just say a b c or d if its right you get brainliest someone anyone pl actually answerrr

nice

Step-by-step explanation:

i think ur answer is   (3,-1)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
