In the study of ecosystems, predator-prey models are often used to study the interaction between species. consider populations of tundra wolves, given by w(t), and caribou, given by c(t), in northern canada. the interaction has been modeled by the equations dcdt=ac−bcw, dwdt=−cw+dcw.
(a) what values of dc/dt and dw/dt correspond to stable populations?

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
