Weight Away, a company that sells weight-loss plans, often advertises the effectiveness of its plans by highlighting the stories of a few clients who have lost extraordinary amounts of weight. To get a better indication of the general effectiveness of the plans, we asked Weight Away to send us information about "typical" clients. Weight Away mailed us a brochure with the following histogram, which displays the weight loss (in pounds) over the past month for Weight Away clients. (Note that a negative value for weight loss represents a weight gain.) Based on the histogram, estimate the mean weight loss (in pounds) for this sample of Weight Away clients. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place.

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change.
