Question

1. which hours training and the minutes to complete race combination is not correct? (1, 30) (3, 25) (0, 40) (8, 0)

Explanation:

Step1: Analyze the graph

The graph shows a relationship between hours training (y - axis) and minutes to complete race (x - axis). As the minutes to complete the race increase, the hours of training should also increase.

Step2: Check each point

• For the point \((1,30)\): If \(x = 30\) (minutes to complete race), looking at the graph, when \(x = 30\), \(y\) (hours training) is around \(1\).
• For the point \((3,25)\): If \(x=25\) (minutes to complete race), when \(x = 25\), \(y\) (hours training) is around \(3\).
• For the point \((0,40)\): If \(x = 40\) (minutes to complete race), when \(x = 40\), \(y\) (hours training) is around \(0\).
• For the point \((8,0)\): If \(x = 0\) (minutes to complete race), but as \(x\) (minutes to complete race) decreases, \(y\) (hours training) should increase. A point \((8,0)\) implies that when \(x = 0\) (no time to complete the race, which is not practical in the context of the graph's increasing trend), \(y = 8\) which does not follow the trend of the line (the line has a positive slope, meaning as \(x\) increases \(y\) increases).

Answer:

\((8,0)\)
