Question

anand keeps track of the number of people inside a music hall to attend a concert by looking at the number of scanned tickets. he plotted the data on the graph below, where ( x = 0 ) represents the time at 6 p.m., then drew a line of best fit. what does the point ( (1.25, 120.3) ) on the line of best fit represent?

at 1:15, there were exactly 120 people in the music hall.
at 1:15, anand should expect about 120.3 people in the music hall.
at 7:15, there were exactly 120 people in the music hall.
at 7:15, anand should expect about 120.3 people in the music hall.

Explanation:

Step1: Analyze the meaning of the coordinate

The point \((1.25,120.3)\) on the line of best - fit means that when \(x = 1.25\) (where \(x\) represents hours past 6 p.m.), the number of people inside the music hall is approximately \(120.3\).
Since \(x = 1.25\) hours past 6 p.m., \(6 + 1.25=7.25\) p.m., which is 7:15 p.m.

Answer:

At 7:15, Anand should expect about 120.3 people in the music hall.
