Mathematics
Investigative Work
S1E3 Group 4
Group members: Esther(24), Jia Wen(21), Shi Bin(39), Sean(33)


Part A
Ans:22.14
Explanation: We use 16 758 114(people from Chille) divide by 756 950Km2 to get the answer 22.13899729 and estimate to 22.14 as the question stated that we must round off the answer to 4 significant figure.

Part B
Ans:3/1700%
Explanation:The question stated that to round off the people in Chille which is 16 758 114 to the nearest million which is 17 000 000 and also told us that 300 people were killed in that earthquake. We were then asked to find the people that were killed as a percentage of the estimated total of people in Chille and we use 300/17000000 x100% and we will get the answer 3/1700%.

Part C
Ans:34.85km and 35.24km
Explanation:The question stated that write any 2 possible numbers that when round off to 4 significant figure, you will get 35km. Therefore, we use these 2 possible answers 34.85km and 35.24km, convert them to metres which is 3485m and 3524m and then round off by 4 significant figures to derive at the answer 3500m which is also the same as 35km.

Part D
Ans:6863440 litres
Explanation: We used the previous questions answer in question part A, 22.14 to find out what is 'c' in this question and the question stated that 'a' is 1.07 litres. Then, we use 22.14 and times (1.07+2.03) and we will get 68.634. After that, we use 68.634 x 1 000 000 to derived at the answer 6863440 litres.

Part E
Ans:13726880
Explanation: the question stated that "For a country to have adequately stocked up on the water supply, they will have to store an amount which is equal to twice of its daily usage". Thus, we use the answer from the previous question part D which is 6863440 litres and so we times 2 which gives us 13726880.

Part F
The price will increase after the earthquake. This is because the people in Chille needs more money, hance the price will become more expensive. The copper would be more difficult to find and also people would need to make even more money to support themselves to survive. Hence, the price will increase.
