Answer:
The answer is below
Explanation:
Probability distribution are statistical function that shows all the possible outcomes of a random variable within a given range of values.
a) The mean (
) of a probability distribution of a discrete random variable is:
![\bar x=\Sigma\ [xP(x)]](https://tex.z-dn.net/?f=%5Cbar%20x%3D%5CSigma%5C%20%5BxP%28x%29%5D)
= (0 * 0.8) + (1 * 0.15) + (2 * 0.04) + (3 * 0.01) = 0.26
b) The standard deviation (σ) of a probability distribution of a discrete random variable is:
![\sigma=\sqrt{ \Sigma\ [(x-\bar x)^2*P(x)]}\\\\\sigma=\sqrt{(0-0.26)^2*0.8+(1-0.26)^2*0.15+(2-0.26)^2*0.04+(3-0.26)^2*0.01} \\\\\sigma=0.577](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt%7B%20%5CSigma%5C%20%5B%28x-%5Cbar%20x%29%5E2%2AP%28x%29%5D%7D%5C%5C%5C%5C%5Csigma%3D%5Csqrt%7B%280-0.26%29%5E2%2A0.8%2B%281-0.26%29%5E2%2A0.15%2B%282-0.26%29%5E2%2A0.04%2B%283-0.26%29%5E2%2A0.01%7D%20%5C%5C%5C%5C%5Csigma%3D0.577)
If there is a withdrawal of cash from a bank which does not go below the required reserves, the withdrawal will not change money supply but will reduce bank checkable deposits.
<h3>What does withdrawing from a bank do?</h3>
If one withdraws money from a bank, it will reduce the bank's checkable deposits as these are made of cash that was deposited by entities.
As regards total money supply however, these withdrawals will only have an impact if the withdrawal causes bank reserves to fall below the required reserves.

Answer:
The correct answer is controlled maintenance.
Explanation:
It is the maintenance whose mission is to maintain a certain level of service in the equipment, programming the interventions of their vulnerable points at the most appropriate time. It usually has a systematic character, that is, it intervenes even if the team has not given any symptoms of having a problem.
Some data transmission networks mess up the messages they send, so if the messages are sent in a certain sequence, they are not guaranteed to arrive in that same sequence. To solve this, the protocol must incorporate a mechanism that allows it to reorder the messages at the destination. This mechanism can be the numbering of the fragments, for example.

Answer: 62 percent
Explanation: A sustainability survey commissioned by the consulting firm KPMG, stated that approximately 62 percent of large and mid-sized companies worldwide have an active sustainability program in place, and that another 11 percent are developing one. Sustainable development is aimed at replacing
economic development, thus encouraging better environmental
