The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...

8.26(10 m) = 82.6 m ≈ 83 m

_____

The distance formula will tell you the distances are ...

AC = √(3² +1²) = √10

BD = √(5² +1²) = √26

The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

Answer:

2. Alex sent the questionnaire only to those who live near her.

Step-by-step explanation:

Given scenario is :

Alex is conducting a survey for a car company. She decides to start by interviewing some people in her neighborhood.

She prepares a questionnaire and emails it to 50 neighbors who own cars. Of those neighbors, 24 respond.

We can see that Alex sent the questionnaire to only her neighbors or people who live near her, so this will be the reason the sample will be biased.
