In a u. s. poll 8 out of 12 citizens said they were happy with the job obama is doing. if 126 people were surveyed how many people were happy with obama?

84 people

Step-by-step explanation:

create a proportion

8            x

  =  

12             126

solve.. cross multiply

128x8 =1008

1008/12 =84

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

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 %
