Question

calvin found census data for the population of idaho from 1870 through 2000. he made the chart and scatter - plot using a line of best fit, which of these would be a reasonable prediction for the population of idaho in 2020? a. 1,600,000 b. 1,400,000 c. 1,200,000 d. 1,000,000 e. 800,000

Explanation:

Step1: Analyze the problem

We are asked to predict population in 2020 using a line of best - fit. But no line of best - fit equation is given.

Step2: Consider requirements

To make a prediction, we need the equation of the line of best - fit (in the form \(y = mx + b\) where \(y\) is population, \(x\) is year, \(m\) is slope and \(b\) is y - intercept) or at least a clear visual trend on the graph with a way to extrapolate to 2020. Since we have neither, we cannot make a prediction.

Answer:

There is not enough information provided in the image to give a specific answer. We would need to know the equation of the line - of - best - fit or have more details about the trend shown in the scatter - plot to make a prediction for 2020.
