Question

1. the scatter plot shows the age of a laptop in months and the hours of battery life that it has. liam thinks a 9 month old laptop will have about 12 hours of battery life. lucas thinks a 9 month old laptop will have about 20 hours of battery life. who is correct and why?

Explanation:

Looking at the scatter - plot, we can observe the trend of the data points. The data points show a decreasing trend as the age of the laptop (in months) increases. When we look at the \(x\) - value (age) of \(9\) months, and follow the pattern of the data points, the \(y\) - value (hours of battery life) is closer to \(12\) than to \(20\).

Answer:

Liam is correct. Because when we analyze the scatter - plot, the data points follow a trend that when the age is \(9\) months, the battery life is approximately \(12\) hours, which is in line with Liam's prediction. Lucas' prediction of \(20\) hours does not match the trend shown in the scatter - plot.
