P (x>14)=e^(-14/16)= 0.4169=41.6% P(X>/=k) Solve for K as K will be the median value. e^(-k/16)=1/2 Shorthand to find the median of an exponential distr. is: Meanxln(2)=k meaning 16xln2=11.09 This is the value of a median, not a percentage.

Ok and thanks alot. But those two are without parentheses.

Precalculus (Logarithmic)
Express each of the given question in logarithmic form. i) e^2x = 15 ii) e^x-4 = 1/2 iii) a^x+1 = 5 Solutions But am not sure if this is the way it should be done. i) e^2x = 15 In (15) = 2x ii) e^x-4 = 1/2 In (1/2) = x-4 iii) a^x+1 = 5 Log 5 with base "a" = x+1

Suppose you are told that log(2)=0.3562 and log(3)=0.5646. All of them with the base of 'a'. Find: i) log(6) ii) log(9) Solutions i) log(6)= log (3)(2) = log 3 + log 2 = 0.5646 + 0.3562 = 0.9208 ii)log(9)= log 3^2 = 2 log 3 = 2 (0.5646) = 1.1292
