Question

which histogram can be used to find how many houses had areas less than 150 square meters? choose 1 answer: a histogram a only b histogram b only c both histograms a and b d neither histogram shows this information

Explanation:

To solve this, we analyze the purpose of a histogram: it groups data into intervals (bins) and shows the frequency (number of data points) in each bin. For finding how many houses have areas less than 150 square meters, we need to check if the histograms (A and B, though their specific binning isn't fully shown here, but the key is the concept) can have bins that include areas <150. If both histograms have bins that cover the range below 150 (e.g., bins like 0 - 50, 50 - 100, 100 - 150, etc., or similar groupings that allow summing frequencies for areas <150), then both can be used. Since the question implies that both histograms have the necessary binning to capture areas less than 150 (as the option "Both histograms A and B" is a choice), we conclude that both can be used.

A histogram shows data frequencies in intervals. To find houses with area <150 m², we need bins covering this range. If both histograms have such bins (implied by the option logic), both can be used.

Answer:

C. Both histograms A and B
