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:
The M2 for October 2010 is $4.4145 trillion
Explanation:
In this question, we are asked to calculate the value of M2 for the month of October 2010. We use a mathematical approach for this;
Mathematically:
M2 = M1 + Savings deposits + Money market funds + Certificates of deposit + other time deposit
We identify the parameters in the question as follows:
Savings deposit = $989.4 billion
Money Market funds = $1.9423 trillion
Certificates of deposit = $345.6 billion
Other time deposit = $243.8 billion
M1 = $893.4 billion
We thus calculate M2 as = $989.4 billion + $1.9423 trillion + $345.6 billion + $243.8 billion + $893.4 billion = $4.4145 trillion
Answer:
Instructions are below.
Explanation:
We weren't provided with enough information to answer the request. <u>But, I will give an example and formulas to guide an answer.</u>
<u>For example:</u>
Production in units:
May=20,000
June= 22,000
Beginning inventory of direct materials= 8,000
<u>To calculate the purchase for May, we need to use the following formula:</u>
Purchases= production + desired ending inventory - beginning inventory
Purchases= 20,000*7 + (22,000*7)*0.29 - 8,000
Purchases= 176,660 pounds
