In circle o, su is a diameter. what is m? 100° 108° 130° 160°

answer: 130

step-by-step explanation:

answer:

the measure of the arc st is 130°

step-by-step explanation:

step 1

find the value of x

we know that

∠sor+∠rot+∠tou=180°

substitute the values

(9x+5)°+(13x+15)°+(9x+5)°=180°

solve for x

(31x+25)°=180°

31x=180°-25°

x=155°/31=5°

step 2

find the measure of the arc st

we know that

arc st=∠sor+∠rot > by central angle

substitute the values

arc st=(9x+5)°+(13x+15)°

arc st=(22x+20)°

substitute the value of x

arc st=(22(5)+20)=130°

answer: x

step-by-step explanation:

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 %
