Answer:
The correct option is b.
Step-by-step explanation:
From the given box plot it is clear that
Minimum value = 26
Maximum value=180
We know that
Since 35 is first quartile it means 25% data lie below 35 and 75% data lie above 35, therefore 75% of workers commute 35 minutes or more to work.
Thus option b is correct.

Answer:
4.4 m
Step-by-step explanation:
Draw the height of the triangle (perpendicular line from point A to line BC). Since ABC is an isosceles triangle, the height is a perpendicular bisector, so it splits the triangle into two congruent right triangles.
Use Pythagorean theorem to find the height.
c² = a² + b²
(8.5 m)² = (14.5/2 m)² + h²
h ≈ 4.4 m
