Question

petra is participating in a program where she takes surveys. the table below shows the number of questions she took each day. which scatter plot matches the table? table and four scatter plots (w, x, y, z) are shown \\(\circ\\) a. x \\(\circ\\) b. z \\(\circ\\) c. y \\(\circ\\) d. w

Explanation:

Step1: List table data points

The coordinate pairs (Day, Questions Answered) are:
$(1,3), (2,7), (3,10), (4,5), (5,3), (6,0), (7,6), (8,8), (9,4), (10,9)$

Step2: Match points to scatter plots

Check each plot:

• Plot W: Has a point at $x=6, y=0$, and matches all pairs: $(1,3), (2,7), (3,10), (4,5), (5,3), (6,0), (7,6), (8,8), (9,4), (10,9)$
• Plots X, Y, Z have mismatched y-values for multiple x-values (e.g., X has $x=6,y=0$ but $x=3,y=4$ which is wrong; Y/Z have incorrect $x=6,y=0$ paired with wrong other points)

Answer:

D. W
