Question: I'll medal

OpenStudy (howard-wolowitz):

@Michele_Laino

OpenStudy (michele_laino):

here, you have to do the scatter plot, first

OpenStudy (howard-wolowitz):

ok

OpenStudy (howard-wolowitz):

can you show me the example because just looking at the numbers. which is what i did I am thinking C because it had a lot of growth

OpenStudy (michele_laino):

from your data, I see that the number of bacteria is decreasing, and, I think that this behaviour can be modeled by an exponential decay

OpenStudy (michele_laino):

the function which can model your data is like below: \[\huge y = A{e^{Bx}}\] so, using your data, we have to establish the value of the constants \(A,B\)

OpenStudy (michele_laino):

In general, we don't work on that function, above, we prefer to work on this equivalent function: \[\huge \ln y = \ln A + Bx\]

OpenStudy (michele_laino):

so we have to apply the linear regression method, to the last function above

OpenStudy (michele_laino):

can you a drawing of the corresponding scatter plot, please?

OpenStudy (michele_laino):

oops.. can you make a drawing...

OpenStudy (howard-wolowitz):

yes
