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

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
