elephant conservation kenya
Oh my gosh, this question is impossible.?
b) Calculate the mean mass of the tusks of the elephants killed in the Kenya-Tanzania border area, using the information in the African Wildlife News excerpt.
African Wildlife News May – June 1997
Altough illegal killing has remained well below the pre-ban level [banning of the sales of ivory enacted 1989] in some areas poaching has increased. At least 10 elephants in Kenya-Tanzania border area have been killed in the last 15 months alone. In 1996 over 5 tonnes of ivory were discovered in Tanzania, possibly taken from as many as 1000 elephants, conservation experts say
Does anyone understand this grade eight math? D:
Well, you know that mean mass is average mass.
So we assume that the number of elephants that the tusks are taken from is actually 1000 elephants. Then we say that the total weight from all those 1000 elephants was 5 tonnes (or 5tonnes x (1000kg/1 to n) = 5000kg
Now the mean weight is 5,000 kg/1,000 elephants…
That is your mean mass per elephant.
Hope it helped!
