It invalidates his hypothesis because it is possible for the time a trip takes to depend on the distance that is traveled during the trip.
Option C is the right answer.
The missing graph has been attached with the answer.
<h3>What is a Scatter Plot ?</h3>
These are Cartesian Points and it represents relationship between two variables.
It is given that
Will's Hypothesis is time can never be a dependent variable.
Although from the graph plotted it can be seen that the time is dependent on distance travelled and
the in a scatter plot , the dependent variable is plotted on y axis and here the time is plotted on y axis ,
therefore the scatter plot invalidate Willis’s hypothesis.

= 7(x^2 + y^2 - 4x + 6y - 5)= 0
= 7( (x - 2)^2 - 4 + (y + 3)^2 - 9 - 5) = 0
= 7[ (x - 2)^2 + (y + 3)^2 - 18) = 0
center is at (2,-3) and radius = sqrt18 = 4.24 units

Step-by-step explanation:
Answer:
50 feet
Step-by-step explanation:
Given:
Vertical height of lift by escalator (h) = 25 ft
Angle of inclination of escalator (x) = 30°
Now, the person traveling along the escalator is equal to the length of the escalator from bottom to top.
Now, a triangle can be constructed using the above scenario.
Consider a right angled triangle ABC with:
AB → Vertical height of escalator = 25 ft
AC → Length of escalator = ?
Now, using trigonometric ratio for sine, we can find the length AC.
This gives,
Therefore, the distance of travel of a person from bottom to top of the escalator is 50 feet.
