Ideally, the smaller the sample population, the more accurate is the sampling result, but it will take longer time if the number of samples is huge. 

The answer to the above question is ideally 20 light bulbs per sampling.

Answer:

ASA

Step-by-step explanation:

Given:

Two triangles ABC and EDC such that:

AB ⊥ BD and BD ⊥ DE

C is the midpoint of BD.

The two triangles are drawn below.

Since, AB ⊥ BD and BD ⊥ DE

Therefore, the two triangles are right angled triangle. The triangle ABC is right angled at vertex B. The triangle EDC is right angled at vertex D.

Since, point C is the midpoint of the line segment BD.

Therefore, C divides the line segment BD into two equal parts.

So, segment BC ≅ segment CD (Midpoint theorem)

Now, consider the triangles ABC and EDC.

Statements                                             Reason

1. ∠ABC ≅ ∠CDE                         Right angles are congruent to each other

2. BC ≅ CD                                   Midpoint theorem. C is midpoint of BD

3. ∠ACB ≅ ∠ECD                         Vertically opposite angles are congruent

Therefore, the two triangles are congruent by ASA postulate.

So, the second option is correct.
