6. Traveling to work Refer to Exercise 2. The histogram displays the data
using intervals of width 1.
Number of states
15
30
18 21 24
27
Average travel time (min)
(a) In what percent of states is the average travel time at least 20 min?
(b) Describe the shape of the distribution.
(C) Which two states are possible outliers with average travel times of less than
16 min?

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.

your answer is b.
