The probability density function (p. d.f.) of a continuous random variable xx is defined to be:

f(x)={x/6+k for 0

0 otherwise,

for some constant k. for these problems, ensure your answers are accurate to within 3 decimals.

part a)

find the value of k that makes the above function a proper p. d.f.

part b)

hence find p(0.5)

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the answer is simply just 6n add the two together as they have an n

114 plus 113 times 2 and 114 times 3
