A newly appointed school district superintendent releases a plan for the next 20 years that affects the schools within the boundaries of the district. In this plan, there is new policy that states that if a high school has less than 100 students, then the school will be shut down. Calamanco High School has a population of 1,417 students, but it is losing students at an average rate of 109 students per year. This school used to house more than 5,000 students but the district has been struggling in recent years and losing people to more affluent nearby districts and cities. Some communities are concerned about this decreasing rate because there will be a time when the district may shut the school down. Let xx represent the number of full years that the school is operational. Part A: If this trend continues, write a function that gives the student population at Calamanco High School after xx years before the school is shut down by the district. Part B: What constraints does this situation put on the domain and range of the function?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
