Aportion of the graph of f(x) = −x2 − 2x + 8 is shown. which of the following describes all solutions for f(x)?
a partial parabola opening down and passing through negative 4 comma 0 and 2 comma zero with endpoints at negative 5 comma negative 7 and 3 comma negative 7
a). (x, −x2 − 2x + 8), where −5 ≤ x ≤ 3
b). (x, y), where −4 ≤ x ≤ 2
c). (x, −x2 − 2x + 8), where −4 ≤ x ≤ 2
d). (x, y) for all real numbers

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
