Teavana has a shop in the airport and offers samples of the newest flavors of tea. Travelers who are waiting for their flights can taste the new tea at Teavana and answer a short survey on a tablet handed to them by a Teavana employee about the latest flavor. This is an example of which type of primary data

- Computer-assisted self-interviewing.

Step-by-step explanation:

'Primary data' is characterized as the data or the information gathered firsthand for a particular purpose or research. Such data is collected personally through surveys, observations, and direct interviews.

As per the details, the given data illustrates 'computer-assisted self-interviewing' as the kind of primary data as the data is collected directly from the travelers visiting the airport using the brief survey method on a tablet. This will help Teavana make credible inferences regarding the people's reviews about their latest tea flavors so that they can make necessary alterations as per the likes and preferences of the people.

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.
