Find the measure of AB¯¯¯¯¯¯¯¯. A. 11 B. 13 C. 12 D. 14

A. 11

Step-by-step explanation:

BC×AC = DC × LC

7(2x +3 +7 ) = 9 ( x+ 1 +9)

7 ( 2x +10) = 9( x + 10 )

14x - 9x = 90 - 70

5x = 20

x = 4

then,

AB = 2x + 3

= 2× 4 + 3

= 11

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 %
