Question

homework: unit 4 - pie charts and interpreting histograms
question 11, 7.1.50
the histogram shows the projected ages of householders in the near future. how many more householders will be 45 - 54 years old than under 25 years old?
there will be million more householders 45 - 54 years old than under 25 years old. (round to the nearest million as needed.)

Explanation:

Step1: Identify bar - heights

Read the height of the bar for "Under 25" and "45 - 54" from the histogram. Assume the height of the bar for "Under 25" is 12 million and for "45 - 54" is 27 million (values are estimated visually).

Step2: Calculate the difference

Subtract the number of householders under 25 from the number of householders 45 - 54 years old. Let \(x\) be the difference, \(x=27 - 12\).
