Please help and explain. Will rate. Thank you suppose that a takes place between and the sample was the second sample sample, namely that after the second sample was collected but before the third collected. In order to describe the the third sample is inside the control limits probability that which one of the following expression should be used? (a) Prob E [LCL, UCL]I00C) (c) Prob(R e [LCL, UCL] IC) 1 a; [Note: IC stands for \"process in control\", and ooc stands for \"process is out of control l is Solution IN THESE TYPE OF QUESTIONS THE NOTATIONS ARE VERY INPORTANT TO JUDGE AND AS IT IS GIVEN THAT THE CHANGE HAS TOOK PLACE BETWEEN 2ND AND THE 3RD THE NOTATION THAT EVENT 3 LIES INSIDE THE CONTROL LIMITS WILL BE THE OPTION C AS IN OPTION C IT IS GIVEN THAT X E WHICH MEANS X BELONGS TO THE LCL , UCL (IN CONTROL) = 1- ALPHA ALPHA IS THE VALUE BY WHICH IT IS DEVIATED HENCE, OPTION C IS CORRECT..

Solution
1.valence electrons are located in the orbitals of outermost orbit
2.An atom of an element is convert to positive ion by loss of electrons.
Na------------ Na+ + e-
An atom of an element is convert to negaive ionby gain of electrons
Cl + e- -------------- Cl-
3.
Al2S3------------- 2 Al+3 + 3 S-2
metal atom Al is exists as Al+3 (+3)= A
CoSO4 ------------ Co+2 + SO4-2
metal atom Co is exists as Co+2. (+2) =B
AgCl ------ Ag+ + Cl-
metal atom Ag exists as Ag+ ( +1) = C
VS3--------- V+6 + S-2
metal atom exists as V+6 ( +6) = D
NiO---------- Ni+2 + O-2
metal atom exists as Ni+2 ( +2) =B
Mn3(PO4)5------------ Mn+5 + PO4-3
metal atom exists as Mn+5 (+5) =E
4,8 electons, octet ruel
5. Poly atomic ions contains morethan one atom in its formula

Based on the following data, what is the working capital? Accounts payable $ 30,000 Accounts receivable 60,000 Accrued liabilities 5,000 Cash 40,000 Fixed assets 670,000 Intangible assets 50,000 Inventory 69,000 Long-term investments 80,000 Long-term liabilities 100,000 Prepaid expenses 1,000 Temporary investments 30,000 a. $130,000 b. $95,000 c. $30,000 d. $165,000 Solution Total current assets=Accounts receivable+Cash+Inventory+Prepaid expenses+Temporary investments =(60000+40000+69000+1000+30000)=$200,000 Total current liabilities=Accounts payable+Accrued liabilities =(30000+5000)=$35000 Working capital=Total current assets-Total current liabilities =(200,000-35000) =$165000..

Which of the following wireless standards uses direct sequence spread spectrum (DSSS) by default? A. Bluetooth B. 802.11a C. 802.11b D. 802.11ac Solution C. 802.11b uses direct sequence spread spectrum (DSSS) technology. DSSS is a transmission method that transmits the data along with a chipping bit to increase the signal’s resistance to interference. Answer A is incorrect because Bluetooth uses frequency-hopping spread spectrum. Answer B is incorrect because 802.11a uses orthogonal frequency-division multiplexing. Answer D is incorrect because 802.11ac uses MIMO-OFDM.

Why do you need to use aprotic solvents (THF, diethyl ether) in a Grignard Reaction? Solution RMgX is general representation of grignard reagent it exist as R- and MgX+ R- is very strong base. if we use any protic solvents like H2O and ROH R- abstracts proton from solvent becomes neutral R- + H2O -------------> RH so there will be reaction between grignard reagent and protoc solvent. so we must use aprotic solvent to avoid above mentioned problem..

Which has more power, business or society? In a major confrontation, which will win? Explain with an example. Solution I think society has more power than business. Therefore, in a major confrontation, the society will win. Businesses cannot survive in a conflict with the society. Businesses survive as long as they fulfill the needs of the society. Therefore, society is primary and businesses are secondary. Society comes with people, systems, traditions, emotions, ethics, etc. Businesses must adapt to the realities of the society and businesses cannot survive without being in a very cohesive and integrated relationship with the society. It is the resources, people, etc. of the society which makes the existence of businesses possible. For example, would Walmart be able to survive without hiring workers from the society, or sourcing materials from different stakeholders of the society, or using infrastructure, the judicial system, political system, payment system, education, system, or selling its goods and services to the society? Walmart will collapse in a day without active support from various stakeholders of the society. In a major confrontation, Walmart will cease to exist and the society will win..

Which of the following statements is true for ideal gases, but is not always true for real gases? Choose all that apply There are no attractive forces between molecules. Pressure is caused by molecule-wall collisions Replacing one gas by another under the same conditions, has no effect on pressure. Molecules are in constant random motion. Submit Answer Retry Entire Group 2 more group attempts remaining Solution 1. It is true that in real gases the attractive forces cannot be neglected. 2.In the real gas, the compressibility factor is not equal to 1. This implies that the molecule-wall collisions are in fact carry a prominent significance in projecting Pressure. 3. In ideal gases, the particle size is assumed to be constant and the interatomic spacing is considered to be almost negligible but it\'s not true in case of real gases..

What special problems does ECB? confront? A. The ECB must function with a highly centralized structure. B. The ECB is required to employ separate interest rate policies for each of the member nations. C. The ECB must coordinate the use of multiple currencies. D. The decentralized organization of the ECB with the governors of the national central banks holding a majority of the? votes, instead of the executive? board, may make it harder to achieve a consensus during a crisis. Solution D) The decentralized organization of the ECB with the governors of the national central banks holding a majority of the votes, instead of the executive board, may make it harder to achieve a consensus during a crisis. (The ECB is the central bank for the euro while managing monetary policy of the Eurozone, consisting of 19 EU member states).
