    Inflation high -> Domestic prices rise -> Export prices become more expensive and import prices become cheaper If there's a fall in its inflation rate, then export prices will decrease and import prices increase -> leads to deterioration in terms of trade

    y = 2x + c and y^2 = 4x x = (y-c)/2 and x = y^2/4 Since the line is a tangent to the curve, then (y-c)/2 = y^2/4. And then you'll get 2y^2 - 4y + 4c. Their discriminant must be equal to zero. Thus, 16 - 32c = 0 -> c = 16/32 -> c = 1/2

    (i) E(x) = np > (or equals to) 8 p = 0.65. Thus, n x 0.65 > (or equals to) 8 n = 12.3 thus minimum trial is 12.3, make it to 13.
