Find the domain and range and show work

See step by step

Step-by-step explanation:

The domain  is possible x-values and the range is possible y-values. Let look at the figure, to find possible x-values. This is a parabola we are dealing with. Parabola are made from quadratic equations. In quadratic equations, you can have any x-value which why the lines extended infinitely to positive x-value and negative x- value so the domain is all real numbers or in interval notation ( -∞,∞). The range shows us that we have an finite number of y-values but it starts at a specific points as it starts at y=2 and there is no point above that so the the range is all real numbers less than or equal to 2. or in interval notation (-∞,2].

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:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
