Let X be an exponential random variable with parameter 2. Find the CDF of X . Express your answer in terms of x using standard notation. Use 'e' for the base of the natural logarithm (e. g., enter e^(-3*x) for e−3x ). a) For x≤0 , FX(x)= unanswered b) For x>0 , FX(x)=

    for      

and      for  

Step-by-step explanation:

Remember that the CDF of an exponental random variable is given by

where     is the parameter.  In this case      so, for this case

what does muffins have to do with anything?

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
