A car manufacturing company is evaluating the effect of a new engine design on fuel efficiency. A random sample of 55 cars is assembled using the new design, and their miles per gallon (mpg) are recorded. The mpg values are assumed to be normally distributed with a known variance of 9. The sample mean mpg is found to be 32. Calculate the 99% confidence interval for the average mpg of all cars assembled with the new engine design.

QUESTION 3 [TOTAL MARKS: 25] Part 1 Three parallel plate capacitors and a power supply are connected as shown. C V 3C C Q3(a) [5 Marks] Calculate the equivalent capacitance. Show your work. Q3(b) [5 Marks] The charge on the top plate of the top capacitor is Q. What is the charge on each of the other five plates? Copy the circuit diagram and clearly indicate which plate has which charge. Q3(c) [3 Marks] Derive an expression for Q in terms of C and V (i.e., write an equation in the form Q=..., where the right hand side only contains constants and the variables C and V). Part 2 Three resistors and a power supply are connected as shown. R V RO 2R Q3(d) Calculate the equivalent resistance. Show your work. Q3(e) [5 Marks] [4 Marks] The current through the battery is /. What is the current through each of the resistors? Copy the circuit diagram and clearly indicate which resistor has which current. Q3(f) [3 Marks] Derive an expression for / in terms of V and R (i.e., write an equation in the form /=..., where the right hand side only contains constants and the variables V and R).

Consider the functions f: AB, g: BC, and h: CD, where A = {b}, B = {a, b, z}, C = {}, and D = {1, 2, 3}. The functions are defined by the following relations: f = {(b, b)}, g = {(a, a), (y, y), (z, z)}, h = {(2, 2), (3, 3)}. (a) Define f^(-1) or explain why it is not invertible. (b) Define h o g (as a set of ordered pairs). (c) Define g o f (as a set of ordered pairs). (d) Are h o g o f and h o g o f the same function? Why or why not?
