A biologist studied the populations of white-sided jackrabbits and black-tailed Jackrabbits over a 5-year period. He modeled the populations, in thousands, with the following polynomials where x is time, in years.

White-sided jackrabbits: 6.5x^2 – 8.7x + 5.9
Black-sided jackrabbits: 6.5x² + 9.2x + 1.2

What polynomial models the total number of white-sided and black-sided jackrabbits?

answer: 298143

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

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 %

80 the answer is 80
