For 3, you may be sampling from people you may or may not know, so everyone has the same rate of being sampled, which is fair.
Answer:
11) x = 11
12) x = 11
Step-by-step explanation:
11) Δ RQP and Δ RLK are similar.
Hence, the ratios of the corresponding sides of the two triangles will be constant.
So,
⇒
⇒
⇒ x - 4 = 7
⇒ x = 11 (Answer)
12) Δ QRS and Δ QDC are similar.
So,
⇒
⇒ 2x - 14 = 8
⇒ 2x = 22
⇒ x = 11 (Answer)
