must the number of people at a party who do not know an odd number of other people be even? Solution In a graph theory, know that “the number of vertices of odd degree is even”. By applying the above principle to the graph with each person as a vertex and an edge between two people who do not know each other. Then yes. it must the number of people at a party who do not know an odd number of other people be even.

4. Use your solubility table to predict whether the following compounds will be soluble in water
at 25°C: (5 points) CompoundSoluble/Insoluble CaSO4 K2SO4 Ba(OH)2 BeS CuCl2
Solubleinsolüble Compound Mg(NO3)2 CaCl2 Al2S3 (NH4)3PO4 SrCO3
Solution
First see the rules of solubility:1)Rule for phosphates says all phosphates are insoluble except for
the alkali metals and NH4+.
2) Rule for nitrates: All nitrates are soluble.
3) Rule for sulfides: All sulfides are insoluble except those of the alkali metals, alkali earths, and
NH4+.
4) Rule for Chlorides: All chlorides are soluble except AgCl, Hg2Cl2, and PbCl2
Mg(NO3) Soluble in water
CaCl2 Soluble in water
Al2S3: Aluminum sulfide actually reacts with water to form aluminum hydroxide and hydrogen
sulfide gas.Thus it decomposes in water instead of dissolving.
(NH4)3PO4: Soluble in water
SrCO3: not soluble in water. t dissolves in water
caso4 : yes Soluble in water
K2SO4 :yes Soluble in water
Ba(OH)2 : yes Soluble in water
BeS: yes Soluble in water
CuCl2: yes Soluble in water.
Acids are substances that form hydrogen ions, H+(.pdf
Acids are substances that form hydrogen ions, H+(aq), when dissolved in water In
acid solutions there are more H+ ions than OH- ions. Bases which are soluble in water are called
alkalis e.g. NaOH sodium hydroxide, KOH potassium hydroxide or Ca(OH)2 calcium hydroxide.
Bases which are water insoluble include CuO copper(II) oxide, MgO magnesium oxide. After a
neutralisation, the salt solutions consist of a mixture of positive and negative ions (and their
names are in the salt name!) e.g. sodium chloride (NaCl) is a mixture of Na+ and Cl- ions,
calcium chloride (CaCl2) is a mix of Ca2+ and Cl- ions; magnesium nitrate (Mg(NO3)2) is a
mix of Mg2+ and NO3- ions, aluminium sulphate (Al2(SO4)3) consists of Al3+ and SO42- ions
etc. You can test for chloride ions by adding a few drops of dilute nitric acid followed by a few
drops of silver nitrate solution. If chloride ions are present you will see a white precipitate of
silver chloride. However, chlorine water itself will contain chloride ions as chlorine in aqueous
solution disproportionates to form chloride and chlorate(I) ions. Cl2 + H2O --> Cl- + ClO- +
2H+ Testing for the presence of nitrate via wet chemistry is generally difficult compared with
testing for other anions, as almost all nitrates are soluble in water. In contrast, many common
ions give insoluble salts, e.g. halides precipitate with silver, and sulfates precipitate with barium.
The nitrate anion is an oxidizer, and many tests for the nitrate anion are based on this property.
Unfortunately, other oxidants present in the analyte may interfere and give erroneous results.

Acids, bases and salts
The three main categories of chemical compounds are acids, bases and salts. These compounds are always part of our daily lives in terms of what we eat and use. The human body contains some very common acids like dilute hydrochloric acid in the stomach, which aids in digestion of food. If the contents of our stomach become too acidic, it results to a burning sensation in the stomach. Acids and bases also regulate metabolic activities in the human body through equilibrium processes. Acids contain hydrogen ions (H+). A base is a substance, which on dissolving in water yields hydroxyl ions (OH-) as the only negative ions. Salts are formed by the combination of an acid and base.

Below are the sequences of portions of the yfg1 mRNA and three yfg1 mRNA variants (A, B,
and C) from zebrafish embryos.
5’...GAUGAAAGAUCAGGUCUGAAUGUAU...3’ yfg1 mRNA
5’...GAUGATTCAUCAGGUCUGAAUGUAU...3’ Variant A
5’...GAUGAAAGAUCAGGACAGAAUGUAU...3’ Variant B
5’...GAUGAAAGAUCAACUCUGAAUGUAU...3’ Variant C
You’ve created a probe which is 100% complementary to the sequence of the yfg1 mRNA:
5’...TTCAGACCTGATCTTTCATC...3’.
You hybridize the probe to a blot of total zebra fish RNA at room temperature (20C), and then
want to adjust the stringency by washes at 50C. Which of the four mRNAs will you “see” as
bands on film when you develop your northern blot?
A. yfg1 alone
B. yfg1 and A
C. yfg1 and B
D. yfg1 and C
E. all of them
F. none of them
PLEASE ANSWER ALL QUESTIONS AND EXPLAIN I WANT TO UNDERSTAND!
Solution
the reverse compliment of 5’...TTCAGACCTGATCTTTCATC...3’is :
GATGAAAGATCAGGTCTGAA. the sequence similarity for the 4 mRNAs will be:
5’...GAUGAAAGAUCAGGUCUGAAUGUAU...3’ yfg1 mRNA
5’...GAUGATTCAUCAGGUCUGAAUGUAU...3’ Variant A
5’...GAUGAAAGAUCAGGACAGAAUGUAU...3’ Variant B
5’...GAUGAAAGAUCAACUCUGAAUGUAU...3’ Variant C
50C is high stringency wash, and it allows up to 5% mismatch.
from our observation, variant A has 3 bp mismatch, and B&C has a 2bp mismatch. 5% of 20 mer
probe is 1bp. thus all the 3 variants have more than a 1bp mismatch, all 3 variants will not be
visible/detected as bands on film. Hence, the answer is option A. yfg1 alone.

a) void cleanse(vector & v)
Implement a function that replaces in a vector each occurrence of the number 0 with the number
1 and the number 13 with the number 7 and leaves all other values unchanged. For example, the
function would convert (13, 1, 0, 26, 7) to (7, 1, 1, 26, 7). A declaration of the function is shown
above
b) int minValue(const vector & v)
Provide an implementation of the minValue function whose declaration is shown above. The
function takes a single argument, which is a vector of int. The function returns the smallest int
that is in the vector.
c) int search(const vector & v, int k)
Implement a function that searches for a given value in a vector of integers. If the value is found,
the function returns the index of the value in the vector otherwise it returns 1. Do not assume the
values are in order do not use binary search. For example, for v = ( 2, 4, 18, 6) the function
returns 1 for k = 1 and 2 for k = 18. A declaration of the function is shown above.
Solution
Hi,
I have implemented function that you have posted. I have one changes in function signature.
While declaring any vector, we need to specify its type. In your question, you have written
function siganture nut this signature is not valid.
Ex.: void cleanse(vector & v) // Its wrong
void cleanse(vector & v)
#include
#include
#include
using namespace std;
void cleanse(vector& v)
{
for (vector ::iterator itr = v.begin(); itr != v.end(); itr++)
{
if (*itr == 0)
*itr = 1;
else if (*itr == 13)
*itr = 7;
}
}
int minValue(const vector & v)
{
int min = v[0];
for (int i = 1; i < v.size(); i++)
{
if (min > v[i])
min = v[i];
}
return min;
}
int search(const vector & v, int k)
{
int retVal = 1;
for (int i = 0; i < v.size(); i++)
{
if (v[i] == k)
{
retVal = i;
break;
}
}
return retVal;
}
int main()
{
vector vect = { 13, 1, 0, 26, 7 };
DisplayData(vect);
cleanse(vect);
DisplayData(vect);
cout << \"\ Min : \" << minValue(vect);
int val;

What is the number of intersection of n points, where no 3 are on the same line?
Solution
two points are required to form a line if we have n points then there will be n/2 points
If you choose n lines randomly, they will intersect at (n2n)/2different points almost surely.
More systematically: Choose n directions for the nn lines such that no two lines are parallel.
Then every line will intersect every other line, and you get (n2n)/2 points of intersection unless
there happens to be some point where three or more lines intersect
so we have n/2 lines so we have (n2/4n/2)/2 points.

What is outsourcing?
- When would it make sense based on quantitative factors only for companies like Toyota and
Boeing to outsource?
- What are 3 qualitative factors that companies like Toyota and Boeing should consider before
outsourcing?
Solution
Outsourcing is when one company hires anther company to perform some of its functions on a
contract basis.The main motive is to save costs and increase profits.For eg. A call centre.
It would not make sense for companies like Toyota and Boeing to outsource based only on
quantitative factors
such as costs.
Qualitaive factors they should consider before outsourcing:
1) Employee Morale : outsourcing leads to lay offs , which may have an adverse effect on the
remaining employees
who may fear that they may be the next to be laid off.
2)Quality :The quality of the goods or services supplied by the external company should be good
, other
wise the reputation of these companies is at stake.
3) Stability of the external company: The company should be financially stable , because if it

What is a current liability? Distinguish between a current liability and a long term debt.
Solution
Current liabilities are those liabilities which become due or obligation are to be meet within
a(one) normal accounting cycle.
Examples of current liabilities are accounts payable, expenses payable, short term loans, etc
Difference:-
Current liabilities becomes due or obligation are to be made within a(one) accounting cycle and
these are also recurring in nature.
But long term debts are debts which becomes due or obligation for payment arises after a period
of one accounting cycle i.e.after 12 months, and these are non reccurring in nature..

visit a local specialty store(e.g., sporting goods, cooking product, electronics) and identify a
generic product or commodity that might be de-commoditized and differential through
innovation .
the name of the book is design of pruduct edition 6th ch3 q1
Solution
Decommoditization is the opposite of commidization, where the value of product enriched and
differentiated through innovation and enrichment. In electronics one thing is LED bulb. Now
most of the elecetronics manufacturer produce LED bulb which save energy and have more life.
It can be de-commoditized by innovation and adding value in the LED bulb.Now people are

Validating Credit Cards Credit card numbers are not randomly chosen. There are rules that
determine which credit card numbers are valid. This is a limited attempt to prevent fraud. If you
just make up some number, it is unlikely to be valid. You are going to write a program to
determine if a number is a valid credit card number. A credit card number must have between 13
and 16 digits. The first digit or two deter mines what type of card it is: Begins with Card Type
Visa MasterCard 37 American Express Discover For our purposes, a number that doesn\'t begin
with one of these sequences is not a valid credit card number. The algorithm for validating credit
cards is credited to Hans Luhn of IBM. To illustrate the algorithm, we will use the sample
number 4388576018402626. First, we see that this must be a Visa card, since it starts with 4. To
validate it 1. Double every second digit from right to left. If doubling of a digit results in a two-
digit number, add up the two digits to get a single-digit number. 2 2 4 2 2 4 2 38 1 2 12 2 3) 5 2 8
2 16 (1 6-7) 4 2 2. Now, add all the single digit numbers from the previous step. 4 4 8 2 3 1 7 8
37 3. Add all the digits in the odd places from right to left in the number. 6 6 0 8 0 7 8 3 38 4.
Add these two values together. 37 38 75

What are some of the evolutionary evidence that suggests we evolv.pdf
Use Gauss\'s approach to find the following sum (do not use formulas): 8 + 14 + 20 + 26+ ... +
86. The sum of the sequence is .
Solution
The sequence given is: 8+14+20+............+86
Now to calculate the sum of this sequence using Gauss approach we use the following steps:
Now, 8+86=94;14+80=94;20+74=94 and so on..(basically we are trying to show that the sum of
extreme terms.ie.the sum of 1st and last term,2nd and the second last term and so on, are the
same in a sequence with common difference)
Now,we have to find the number of terms in the sequence.
8=8+0*6 (We are using 6 here as the common difference between the terms of the sequence is 6)
14=8+1*6
20=8+2*6............
86=8+13*6
Hence,the no of terms(n) is 14......Therefore no of pairs is : n/2=14/2=7....This indicates that we
have 7 pairs of numbers whose sum is 94.
The sum of the sequence is= 94*7=658.

Use the definition of the Laplace transform to find L{f(t)}
f(t) = {t, 0 ? t ?
{2
Solution
Definition - Laplace transform of a function f(t) is defined as follows
L{f(t)} = integrate[0, inf] f(t)e-st dt
So for 0 t 1, the questions says f(t) = t and you just plug it into the definition and get integrate[0,
inf]{te-st}dt and evaluate the integral. First step of the intgral is integration by parts, let u=t and
dv/dx = e-st , then integration by part formula says uv - integrate v(du/dx), which gives us [-
(1/s) te-st] - integrate[0, inf] {-(1/s)e-st}dt. Note that the \"uv\" part [-(1/s) te-st] is equal to zero,
and then you just have to integrate by parts the integral part again to get 1/s2
same thing for t 1 . plug in 2-t, and you get L{f(t)}=integrate[0, inf]{(2-t)e-stdt. Notice that the
-t term you already did it in part a so you really just have to integrate 2e-st . which gives you 2/s.

A farmer has the utility function U=C0.5 and faces a choice between planting a risky high yield
variety of maize or planting the traditional variety. The outcomes and probabilities are
summarized in the table below:
Different from the example in class, the farmer is now endowed with an initial wealth level of
500. So his/her consumption is the amount that they get from the Maize planted +500. (e.g., if a
farmer gets 1444 income from maize planting, their consumption is 1444+500=1944).
Q1. What is the farmer\'s Expected Utility should they plant the High-Yield
Maize?VarietyProbability of Good outcomeIncome in Good outcomeProbability of Bad
outcomeIncome in Bad outcomeHigh-Yield Maize0.514440.5100Traditional
Maize0.56250.5625
Solution
In case of High Yield Maize we have Expected Utility equals to
E(U)=Probability of good outcome*U((initial ealth level+Income in good
outcome))^0.5+Probability of bad outcome*U((initial ealth level+Income in bd outcome))^0.5
E(U)=0.5(1944)^0.5+0.5(600)^0.5=34.30

On the basis of the general solubility rules given in the table belo.pdf
- 1. On the basis of the general solubility rules given in the table below, predict which of the following substances are likely to be soluble in water. (Select all that apply.) zinc chloride lead(II) sulfate magnesium carbonate ammonium carbonate Simple Rules for the Solubility of Salts in Water 1. Most nitrate (NO) salts are soluble. 2. Most salts containing the alkali metal ions (Li", Na, K, Cst, Rb*) and the ammonium ion (NH,) are soluble. 3. Most chloride, bromide, and iodide salts are soluble. Notable exceptions are salts contain- ing the ions Ag", Pb", and Hgr. 4. Most sulfate salts are soluble. Notable exceptions are BaSO4. PbSO4, Hg,SO, and CaSO4. 5. Most hydroxide salts are only slightly soluble. The important soluble hydroxides are NaOH and KOH. The compounds BalOH), Sr(OH), and Ca(OH), are marginally soluble. 6. Most sulfide (S), carbonate (CO²), chromate (Cro.?"), and phosphate (PO.') salts are only slightly soluble. Solution There are no such rules about the solubility of ZnCl2 so it is not be soluble in water. According to rule four lead sulphate is soluble. According to rule 6, Magnesium carbonate may be soluble in water. From rule 2 and 6 so ammonium carbonate is soluble in water.
