The number of emails that Dave receives each day at his actuarial job has a Poisson distribution with mean 2 during each weekday and mean 1 each day during the weekend. The number of emails that Dave receives on one day is independent of the number of emails that he receives on the other days. Dave does not receive any personal emails. If today is Thursday, what is the probability that Dave receives his first email two days later, on Saturday

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
