Final answer:
The question encompasses identifying patterns, calculating probability, and categorizing types of data, all of which are aspects of mathematical literacy, focusing on the understanding of mathematical vocabulary and congruence.
Step-by-step explanation:
The question is related to the mathematical concepts of vocabulary and congruence, specifically in the context of mathematical literacy. When sorting words into groups based on the letter that comes after the or in a list of words, we are employing skills in categorization and pattern recognition. This is part of mathematical literacy because it involves understanding and using language that pertains to math concepts.
For the 'Try It Σ' part which asks about the probability in the context of picking letter tiles from a bag, we are dealing with a problem about probability and combinations. The group of interest would be the vowels, the size of the group of interest is 44 (since there are 44 vowel tiles), and the size of the sample is 7 (since you are picking seven tiles).
The terms 'quantitative discrete', 'quantitative continuous', and 'qualitative or categorical' from Solution 1.9 are types of data used in statistics to describe different kinds of variables. These concepts are important for students to grasp in order to correctly analyze and interpret data.
