A nurse measured the blood pressure of each person who visited her clinic. Following is a relative-frequency histogram for the systolic blood pressure readings for those people aged between 25 and 40. Use the histogram to answer the question. The blood pressure readings were given to the nearest whole number.
-Given that 600 people were aged between 25 and 40, approximately how many had a systolic blood pressure reading between 130 and 149 inclusive?

Based on the given age range (25-40) and the specified systolic blood pressure range (130-149), the correct answer would typically be derived from statistical data or a study result that correlates these specific parameters. Without the specific data or context, it's challenging to provide a precise explanation. However, if this question is based on a hypothetical or statistical scenario where a certain percentage of people in this age group fall within the specified blood pressure range, then the answer would be calculated based on that percentage. Assuming B (138) is the correct answer, it might represent a scenario where approximately 23% of the people in the specified age group have a systolic blood pressure within the given range, assuming a statistical distribution or study result that supports this conclusion.
