Problem #10: The standard deviation of X, denoted by SD(X), is defined by SD(X) = V Var(X) Suppose that SD(X) 7. Find SD(9X+ 3). Problem #10:
Theobromine (C7H8N4O2; M=180.2 g/mol) is an alkaloid found in chocolate. 1)Despite having several nitrogen atoms in its sturcture, it is an extremely weak base in water. Provide a reasonable explanation for this behavior? 2)Propose and draw a structural modification to the molecule of theobromine that would transform the substance into a stronger base. Justify your reasoning.

Problem 1: Steady-state error analvsis (a) A block diagram of a feedback control system is given below. Assuming that the tunable constant Khas a value that makes this closed-loop system stable, find the steady-state error of the closed-loop system for (a a step reference input with amplitude R, r(t)- R u(t) (ii) a ramp reference input with slope R, r(t) = Rt-us(t) R(s) Y(s) (s+2)(s +5) (b) A block...
Stuck on this problem any help
would be great thank you
