Need help!!!!!!!!!!!!!!!

If x~MW(alpha1,beta1,lambda1) and y~MW(alpha2,beta2,lambda2)

and we have aserial system with two components x and y (x and y independent)

if alpha1=0.05, beta1=0.02, annd lambda1=1

if alpha2=0.0005, beta1=0.6, annd lambda1=0.1

MW is Modified Weibull distribution Lia and xei 2003

writ R code to
1)simulte from this system with sample size n=10,20,30,40,50,60,70,80,90,100
2)compute the MLE for each sample size
3)compute the standerd erorr and plot it for each parameters with simple size

do anyone know this how to solve????

hi MShrieves1

Welcome to the forum! 

Please, when you have a question, post it in a new post rather than inside someone else's post.

But, to answer your question:

scalene means all angles are different (or all sides ... it comes to the same thing)

obtuse means one angle is over 90

Your last triangle is the only one that has both these properties.

This question is still open from post #1: (sorry for the interruption...)
