Question
A large company has 19 mainframe computers of a certain class. The scatterplot above shows the value and age for each of the 19 computers. A line of best fit for the data is also shown.
Based on the line of best fit, the estimated value of a 6-year-old computer is k thousand dollars, where k is an integer. What is the value of k?
The correct answer is: 15
We need to trace the point k on the given line of best fit to find the corresponding value on y-axis to find the value of a 6 year old computer in thousand dollars.
Step-by-step solution:-
In the given scatter plot, we see that for a 6 year old computer, the corresponding value on the line of best fit for x axis = 6 and on y-axis = 15 (thousand dollars)
∴ the value of a 6 year old computer from the given data set is 15 thousand dollars.
Final Answer:-
∴ The value of a 6 year old computer from the given data set is 15 thousand dollars.
