Let S = {4, 9, 12} be a sample space associated with an experiment. (a) List all events of this experiment.
O 0, {4,9}, {4, 12}, {9, 12}, {4, 9, 12}
O {4}, {9}, {12}, {4,9}, {4, 12}, {9, 12}
O 0,{4}, {9}, {12}, {4,9}, {4, 12}, {9, 12}, {4,9,12}
O 0,{4}, {9}, {12}, {4,9}, {4, 12}, {9, 12}
O {4}, {9}, {12}, {4,9}, {4, 12}, {9, 12}, {4,9,12}
O {4,9}, {4, 12}, {9,12}, {4,9,12}

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

i believe that the answer is

b. y-1=-2(x-4)

hope this !

i think the answer would be c

can you take a photo of the screen?
