Answer:
Step-by-step explanation:
If the ratio of triangle = 6:3:7
Total ratio = 6+3+7 = 16
The sum of angle in a triangle is 180°
1st angle= 6/16 × 180 = 6 × 11.25
= 67.5°
2nd angle= 3/16 × 180 = 3 × 11.25
= 33.75°
3rd angle= 7/16 × 180 = 7 × 11.25
= 78.75°
Largest is 78.75° and smallest is 33.75°
Answer:
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)
Step-by-step explanation:
–1 > –2(x – 4) – 5(4x – 7)
distribute
-1> -2x+8-20x+35
combine like terms
-1> -22x+43
subtract 43 from each side
-44> -22x
divide by -22 (remember to flip the inequality symbol)
2<x
