James surveyed people at school and asked whether they
bring their lunch to school or buy their lunch at school more
often. the results are shown below
the events "male" and "buys lunch" are not independent
because
bring lunch: 46 males, 254 females
buy lunch: 176 males, 264 females
pbuys lunch | male) = p(male) = 0.4
p(male | buys lunch) = p(male) = 0.3.
p(buys lunch | male) = 0.3 and p(male) = 0.4
p(male | buys lunch) = 0.4 and p(male) = 0.3.

y do u put "subscirbe to ence" on a app for ppl who need with their work?

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
