You want to conduct a survey to find out what sport the students at your school prefer to play.

a) you interview 20 boys playing football at lunch. is this a random sample ? explain

b)the survey question you ask is, "what is your favorite sport to play? " is the question fair or biased? explain

plz

a) When interviewing 20 boys playing football at lunch, it is considered a random sample because you are interviewing with a large group of boys.

b) Even though I think is biased, I also think its fair, because of the fact that you are not really sure that their favorite sport is football. It doesn't say like "Oh, they must love playing football and think that's their favorite sport". So it is fair to ask this question, because maybe, that is not their favorite sport.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
