Ski resorts are interested in the average age that children take their first ski and snowboard lessons they need thisinformation to optimally plan their ski classes match the vocabulary word with its corresponding 1. all children who ski and snowboardparameter2. the 92 children who were asked when they took their first lesson3. the average age that all children take their first to lesson4. the average age then the 92 children took their first lesson5. the age that children take their first listen6. the list of the 92 ages that the children from the study took the first listen

Matching the vocabulary word with its corresponding example:

1. All children who Ski and Snowboard = population (a group of items, units or subjects which is under reference of study e.g inhabitants of a region, numbers of cars in a city e.t.c)

2. The 92 children who were asked when they took their first lesson = Sample (a part or fraction of a population selected on some basis)

3. The average age that all children take their first to lesson = Parameter (the number that summarizes some characteristics of a population

4. The average age that the 92 children took their first lesson = statistic (a sample characteristic corresponding to the population parameter used when a sample is use to make inference about a population)

5. The age that children take their first listen = variable (anything that has attribute, quality or quantity that varies or a characteristic/attribute that describes a place, person or thing)  

6. The list of the 92 ages that the children from the study took the first listen = data (facts that are collected together for analysis)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
