Model from Part (a) is dC/dt = E - (C/tau) C - concentration of the gas [Tg] E - emission rate [Tg/yr] t - time [yr] tau - represents the lifetime of the gas in the atmosphere, before it is removed, either by chemical reactions or deposition to the surface
P(X>0.75)= 0.2266 P(X≤−1.25)= 0.1056 E[Z]= -1/4 var(Z)= 9/16 P(−1≤Y≤2)= ?
B=3G+2 ---- (i) B+G=22 ---- (ii) => (3G+2)+G = 22 => 4G + 2 = 22 => 4G = 20 => G = 5 B = 3X5 + 2 = 15+2 = 17
