What grade give this kind of work
Answer:
1. distributive
2. associative
Step-by-step explanation:
In the first one, they are distributing 16 + 23 by the 4.
Therefore it is distributive property as they are splitting and then separately multiplying.
In the second one, the parentheses are shifted. The shifting of parentheses indicates priority, and the associative property says in addition you can choose what you'd like to do first and it won't change the answer.
Answer:
a. 199,389
b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
Step-by-step explanation:
a. Population in 2009 = 192,370
This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389
b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
