Hey maaaaaaaan my brother will help you dsddd
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
.
<span>-5x < 35
5x > -35
x > -35/5
x > -7</span>
Answer:
1/2 or one half
Step-by-step explanation:
Answer:
-2x^2 - 5x
= -2-4^2 - 5*-4
= -2(-4 * -4 ) - (-20)
= -2(-16) +20
= -32 + 20
= -12
