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)
Answer:
$C$8
Explanation:
The Symbol $ means that by copying and pasting to another cell, the cell references will not change.
In this case, the references are "locked" onto column C. Copying the formula to some other location will not change the references since they are absolute.
Answer: b.the principles of management are much the same at large and small firms.
Explanation:
Quinn will find that Management Principles do not discriminate against different sizes of firms and that the principles that work in one size can work across ALL sizes.
She will find that the same Principles that helped her in her big NGO will help her JUST AS WELL in this small but pioneering business.
Answer:
D
Explanation:
Profit is Maximize when MR = MC
since MR=40 - 0.5Q
and MC= 4
Therefore:
40-0.5Q = 4
-0.5Q = 4 - 40
-0.5Q= -36
divide through by -0.5
Q = 72
since Q = 72
from Q = 160 - 4p
72 = 160 - 4P
-4p = 72 - 160
-4P = -88
divide through by -4
P = 22
Answer:
Principal-agent.
Explanation:
This problem comes to play when one has to make decisions on behalf of another person.
The principal-agent problem is a conflict in priorities between a person or group and the representative authorized to act on their behalf. An agent may act in a way that is contrary to the best interests of the principal.
It can occur in any situation in which the ownership of an asset, or a principal, delegates direct control over that asset to another party, or agent.
