consider the fucntion f(x)=2x^3+6x^2-4.5x -13.5. state the roots of this cubic and confim using the remainder theorem.
Roots : -1.5, -3, 1.5
(This is Done)

Here's the problem :-
then,taking the roots two at a time, find the equations of the tangent lines to the average of two of the three roots. Find where the tangent lines at the average of the two roots intersect the curve again?

I dont know how to get the eq. of tangent!

I had to cross and follow the inheritance pattern of Drosophila flies with white eyes. This is a sex-linked recessive trait and is supposed to show up as a 1:1:1:1 ratio. How do I calculate an exact ratio from the data I generated?

F, whi: 103/424
F, red: 118/424
M, whi: 107/424
M, red: 96/424

I understand that it basically supports the 1-1-1-1 ratio, especially through the use of a Chi-square test, but since these values aren't exactly the expected 106-106-106-106 that they're "supposed" to be, what is the exact ratio for my data? Is it still technically 1-1-1-1? How do I go about calculating it?

Thanks!
