Suppose we have a bag with 10 slips of paper in it. eight of these have a 2 on them and the other two have a 4 on them.
what is the expected value of the number shown when we draw a single slip of paper?

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4

Step-by-step explanation:

We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.

The total value of all the slips when added together is:

= (8)(2) + (2)(4)  

=  16 + 8 = 24

The expected value of one draw is the average value of these 10 slips of paper which is:

24 / 10  =  2.4  

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.
