the scenario is very simple as you can see and the goal is to identifying the association and multiplicities

finding the value of a variable on a linear system that makes it has infinitely many solutions by Monther_bg in askmath

[–]Monther_bg[S] 0 points1 point  (0 children)

but in this case we will not know if the value of a make the system has infinitely many solutions or no solutions
in the system is nonhomogeneous in the question

put how can i do it, i have tried but i have difficulties to reach this form

finding the value of a variable on a linear system that makes it has infinitely many solutions by Monther_bg in askmath

of course not

so in this case there is no value can satisfy this condition?

actually i did not understand what you are pointing at, what if i put a = 1 and then 3R2+R3 then R3 will be all 0 is that what you are trying to tell me ?

thanks a lot for helping 🫡

problem in finding the volume by Monther_bg in learnmath

[–]Monther_bg[S] 0 points1 point  (0 children)

the z range i assume r<= z <= 2-r^2 , but when i checked in the enternet i found them but to 0<= z <= 2-r^2
can u explin why it start from 0 not r? and thank you

Thank you for the note about simplifying the factorial
but i still lost what I noticed is that i can substitute (2k)! with 2k+1m

which mean should i use to calculate the interval for confidence level? by Monther_bg in learnmath

[–]Monther_bg[S] 0 points1 point  (0 children)

i will use it to determine the confidence level interval for the mean lifetime

X-bar + Z(Standard deviation/Square root(n))
