Consider the cross: A/a; b/b; C/c; D/d; E/e x A/a; B/b; c/c;
D/d; e/e
a) what proportion of the progeny will phenotypically resemble
the first parent?
b) what proportion of the progeny will genotypically resemble
neither parent?
Let A = {a, b, c, d} and B = {b, d, e}. Write out all of the
elements of the following sets.
(a) B ∩ ∅
(b) A ∪ B
(c) (A ∩ B) × B
(d) P(A\B)
(e) {X ∈ P(A) | |X| ≤ 3}
For the relation R(A,B,C,D,E) with the following Functional
Dependencies:
A → B, A → C, BC → D, AC → E, CE → A,
list all non-trivial FDs following from the above.
Generate all possible keys for R.
Check whether R is in 3NF. If it is in 3NF, explain the
criteria you used. If it is not in 3NF, convert it into 3NF,
showing the new relations and their FDs.
please i need the solve for A&B&C&D&E

The rate of a chemical reaction depends on the concentrations of
the reactants. For the general reaction between AA and BB,
aA+bB⇌cC+dDaA+bB⇌cC+dD

Find A, B, C, D, E such that the rule Af(a − 2h) + Bf(a − h) +
Cf(a) + Df(a + h) + Ef(a + 2h) approximates f"'(a) with the error
O(h^p) for the largest order of convergence p. What is this p equal
to? Please be clear and show all steps, thanks!
