M(8,7) is the midpoint of rs. the coordinates of s are (9,5). what are the coordinates of r?
(8.5,6)
(7,9)
(16, 14)
(10,3)

Answer is (7,9).

Step-by-step explanation:

The midpoint formula for a line is (X1+X2/2 , Y1+Y2/2).

Because every answer has a different X coordinate, you only need to calculate one coordinate. I decided to calculate the x coordinate. So... if you apply the formula...  X1+9/2 = 8. Multiply two on both sides to get X1+9=16.

X1 is 7.

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest

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 %
