Final answer:
The question deals with solving inequalities in algebra, focusing on ranges of possible x values and understanding the behavior of numbers when summed or within a normal distribution.
Step-by-step explanation:
The question focuses on solving an inequality, a core concept in algebra and mathematics education at the high school level. In particular, it discusses finding the range of values that the variable x can take in an inequality. One aspect of solving inequalities involves understanding that adding a number larger than 1 to another number larger than 1 will result in a sum that is also larger than 2.
Similarly, one can infer that the sum of one-third and one-half, which are both less than 1, will be a number that is less than 1. Moreover, when considering the distribution of a set of data, assuming a normal distribution, about 95 percent of the x values lie within two standard deviations from the mean.
