Final answer:
The question likely pertains to applying a mathematical or scientific process described in lemma 1.55, such as converting measurements or calculating probabilities and percentiles in statistics.
Step-by-step explanation:
The procedure described in lemma 1.55 seems to refer to a step-by-step approach to solving a mathematical or scientific problem. From the information provided, this procedure could involve computing equivalents, as with converting meters to centimeters, or it could pertain to statistical calculations such as finding probabilities and percentiles. For instance, to convert 3.55 meters to centimeters, we would multiply by 100, because there are 100 centimeters in a meter, leading to 3.55 * 100 = 355 cm. In statistics, to find P(x < 7) or P(Ex > 170), we would use the appropriate probability distribution and the given sample size of 55 to calculate these probabilities.
In physical science, applying this procedure could mean using a given refractive index, such as n = 1.55 for the glass, to trace the path of a ray through a lens. The key in all applications of lemma 1.55 is to understand the steps involved and apply them accurately to the problem at hand.
