An unknown food-dye is analyzed by the method used in this experiment. The absorbance of 5 standard solutions is plotted vs. their concentration (molarity) and a straight line is obtained with the formula: Abs = 2.850x +0.02 An unknown food-dye solution is diluted and it's absorbance is found to be 0.55. What is the molarity of the diluted unknown, to two significant figures

Julia chooses a card at random from her set of cards. what is the probability that the card is labeled cat or hamster?

Needmax recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
