The answer should be D
Step by Step: |2x-2| <(or equal to) 6
Add 2 on both sides should give you, |2x| < 8
Divide both sides by 2, giving you 4
Other way, is doing the same but -2
Step-by-step explanation:
hi im not really sure if this is right
The event that either M1 or M2 fails has probability

by the addition rule. Failure events are independent, so

so that

Denote this probability by
. Then
follows a geometric distribution with this parameter
and has density

The expectation is
.
Answer:
8
Step-by-step explanation:
500/(2*(4.4*3.2+3.2*2+2*4.4)) = 8.5382513661
