Answer:
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
Step-by-step explanation:
let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that
U≤ l and 1-U ≤l
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
this means 1-l≤U≤l
so we have
if we have L [1/2,1]
then apply the formula we have E(L)=3/4
Answer:
hello good morning.have a nice day
Answer:
34 degrees
Step-by-step explanation:
ok so 180-111=69
then the opposite angle from 37 is also 37
the the missing angle from the left triangle has to be 103
so then the angle below x is 77
and so we know x = 34 degrees
I hope that made sense.
D would be the correct answer. Post brainliest if this helped plz :)
1/4 : 2 or 1/8 : 1. That is how I would have done it. I hope this helps you.
