Mathematics
Investigate Work
S1E3 Group 5
Group Members: Celine Koh (3), Evita Satrio(9), Dzulhaily(28), Moses(29)


Part A
- 22.14
Explaination: We divide 16 758 114 people from 756 950km2 and we get the answer 22.13899729 and we estimate it to 22.14 beacuse the question ask us to round off the answer to 4 significant figures.

Part B
- The Answer is: 3/1700%
Explaination: The question asked us to estimate the total population of Chile to the nearest million and hence, we estimate 16758114 to the nearest million and the answer is 17000000.The question says that there isan estimated population of 300 people and we have to find out the number of people killed as a percentage of the estimated total population of Chile.So, we take 30/17000000 X 100% and the final answers is 3/1700%.

Part C
- 34.89km and 34.95km.
Explanation: 35km is equals to 3500m and the possible values are 34890 and when 34890m is corrected to the 4 significant figures, it is 3400m.

Part D
- 6863440 litres
Explanation: We have to find ‘y’ and ‘y’ is = c(a+2.03)x1000000.’y’ is the amount of water needed by the country per day(in litres),’c’ is the population per square kilometers and ‘a’ is the reserve needed per person, which is 1.07 litres.Hence, we take 22.14 which is the population per square kilometers times (1.07+2.03) and the answer is 68.634.After that we take 68.634 times 1000000 and the final answer is 6863400 litres.

Part E
- 13726800 litres.
Explanation: The question said ‘For a country to be adequately stocked up on water supply, they will have to store an amount which is equal to twice of its daily usage’. Hence, we have time the daily usage of water which is 6863400 tires by 2.So, the answers is 13726800 litres after we take 6863400 litres times 2.


Part F
-After the earthquake, I think the price of the copper will increase. It is because, after the earthquake, many of the people affected lost everything and many of them are homeless and poor. With this situation, the price of the copper will increase because most of the people there would use what they could sell to earn money for their families to provide needs for themselves, for examples, buying food, to fill their stomach.
