Answer:
No; he did the survey incorrectly.
He surveyed 107 people, not 100.
Step-by-step explanation:
Draw a Venn diagram, when you are presented with information like this;
Presenting it in a Venn diagram would look like what is shown in the pic.
P.S. when drawing a Venn diagram, start with the information regarding individuals who fit in all categories and then work your way to the individuals who fit in just in one category.
Considering the two right-angled triangles (ΔABD and ΔBCE) with the following points A(2, 154), B(1, 110), D(2, 110) and E(1, 66).
Since the triangles are similar, the slope of line segment AD is given by:
Tanθ = AD/BE
Tanθ = (154 - 110)/(110 - 66)
Tanθ = 44/44
Tanθ = 1.
Also, the slopes of line segment BD is given by:
Tan∅ = BD/CE
Tan∅ = (2 - 1)/(1 - 0)
Tan∅ = 1/1
Tan∅ = 1.
Therefore, the slope of line segment AD and line segment BD are the same because θ is equal to ∅.
<h3>What are the initial value and slope of the graph?</h3>By critically observing the graph, we can logically deduce that the initial value of this graph is 66 and it represents the shark's distance at the initial time (0 minute).
For the slope, we have:
Slope = Δy/Δx
Slope = (154 - 66)/(2 - 0)
Slope = 88/2
Slope = 44.

Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph, and what do they represent?
