(21 points, need ) in a poll of students attending a basketball game, 84% of the students say that basketball is better than football.

(a) is this poll biased or unbiased? explain.

(b) suggest a better method of determining which sport is more popular.

Chances are, if they are at a basketball game then they're going to say basketball is better

Questioning the entire school would be a better way of determining if football is more popular

Yes, the poll is biased.

Step-by-step explanation: The poll was biased when it was performed because it was conducted with only students who were attending a basketball game. Since they are attending a basketball game there is a very good chance that they are biased in favor of basketball.

A better method of determining which sport is more popular would be to conduct a poll in a neutral area. The poll would be neutral if conducted in a lunch room or some other non-sport area of the school.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
