In 1997 Joseph DeRisi, Vishwanath Iyer, and Patrick Brown conducted an experiment on Saccharomyces cerevisiae using DNA microarrays. Describe their experiment, their hypothesis and their general findings from their study.

can you please do the following?

(8) Step 8: type the following command:

sort /etc/passwd | head -5

What is the output?

Notice that this pipe can be simplified

cat /etc/passwd | head -5

What is the output for this?

You could accomplish the same thing more efficiently with either of the two commands:

head -5 /etc/passwd

head -5 < /etc/passwd

(9) Step 9:

The command displays all the files in the current directory sorted by file size

ls -al | sort -n -r +4

What is the output? What are the outputs sorting according to? Which column is this?

The command ls -al writes the file size in the fifth column, which is why we skip the first four columns using +4.

The options -n and -r request a numeric sort (which is different than the normal alphabetic sort) in reverse order

awk

Topics covered: processing columnar data

Utilities covered: awk

The awk utility is used for processing columns of data

(10) Step 10:

The following example shows how to extract column 5 (the file size) from the output of ls -l

ls -l | awk '{print $5}'

What is the output?

Cut and paste this line into a Bourne shell and you should see a column of file sizes, one per file in your current directory.

(11) Step 11:

The following example shows how to sum the file sizes and print the result at the end of the awk run

ls -al | awk '{sum = sum + $5} END {print sum}'

In this example you should see printed just one number, which is the sum of the file sizes in the current directory.

Shell Scripts

Topics covered: storing commands in a file and executing the file

Utilities covered: date, cal, last (shows who has logged in recently)

(12) Step 12:

Store the following in a file named simple.sh and execute it

#!/bin/sh

# Show some useful info at the start of the day

date

echo Good morning $USER

cal

last | head -6

What is the result after you execute it?(Shows current date, calendar, and a six of previous logins Notice that the commands themselves are not displayed, only the results )

last command - display login and logout information about users and

     terminals

(13) Step 13:

To display the commands verbatim as they run, execute with

sh -v simple.sh

Another way to display the commands as they run is with -x

sh -x simple.sh

What is the difference between -v and -x? Notice that with -v you see '$USER' but with -x you see your login name

Run the command 'echo $USER' at your terminal prompt and see that the variable $USER stores your login name

With -v or -x (or both) you can easily relate any error message that may appear to the command that generated it

(14) Step 14:

When an error occurs in a script, the script continues executing at the next command

Verify this by changing 'cal' to 'caal' to cause an error, and then run the script again

Run the 'caal' script with 'sh -v simple.sh' and with 'sh -x simple.sh' and verify the error message comes from cal

Other standard variable names include: $HOME, $PATH, $PRINTER. Use echo to examine the values of these variables

Henry Hawkins uses an accrual-based accounting system. That means they report sales revenues on the income statement in the period the revenues are earned and they report expenses on the income statement in the period the expenses were incurred to earn the revenue.

Based on the following information, calculate the cash received from customers for 2016.

Sales for 2016 (all on account) $1,545,000

Accounts receivable, January 1, 2016 $81,600

Accounts receivable, December 31, 2016 $100,800

Cash received from customers in 2016

Assume that the only thing happening in Accounts Payable is the purchase and payment of inventory. Based on the following information, calculate the cash paid for inventory for 2016:

Cost of goods sold $525,000

Inventory, January 1, 2016 $158,600

Accounts payable, January 1, 2016 $66,700

Inventory, December 31, 2016 $130,400

Accounts payable, December 31, 2016 $82,000

Cash paid for inventory in 2016

Given a list of positive integers c[0...n − 1], and a positive integer v, decides whether we can use numbers from c[0...n − 1] to make a sum of v, allowing any particular number in the list to be used multiple times. Or, mathematically, this means that there exists non-negative integer coefficients, x0, x1, ..., xn−1, such that v = x0c[0] + x1c[1] + ...xn−1c[n − 1].

For example, given c[0...3] = {2, 4, 6, 10}, and v = 17, the function shall return false, as it’s impossible to use numbers from c to add up to 17.

Given c[0...3] = {2, 4, 6, 10}, and v = 34, the function shall return true, as 34 can be expressed as 17 2’s added up (there are other ways to make value 34 as well).

Based upon the pseudocode given at the end,

(a) implement and test the following C++ function (minimally, you shall test the function with examples given above.

       /* Return true if v can be expressed as sums of values from coins (repetition is allowed)
       @param coins is a vector of positive int values
       @param v is a positive int
       @return true if v can be written as a sum of values from coins, return false otherwise

       */
       bool CoinChange (vector<int> coins, int v)

(b) In comment of your code, provide a tracing of the function’s execution with input: coins[0...3] = {3, 4, 6, 10}, and v = 14. You should:

• list in order the recursive calls made, with the parameters passed and values returned for each call.

• Comment on when backtracking happens.

Pseudocode

/*
Return true if v can be expressed as sum of values from c[0...n-1] @param c[0...n-1]: stores n positive integers
@param v: non-negative integers

2

*/
bool CoinChange (c[0...n-1], v) {

if (v==0)

for i=0 to n-1: if (c[i]==v)

//fill in the blank here

 //fill in the blank here

else if (c[i]<v)
//Think: if we include c[i] to make change amount of
// v, then we only need to make change amount of _____
if (CoinChange (c, ) == True): //fill in the parameter for the

                   return true; //function call above

    // If we haven’t returned true by now, return false
    return false;

Ascorbic asic (0.0100 M) was added to 10.0 mL of 0.0200 M Fe3+ at pH = 0.30, and the potential was monitored with Pt and saturated Ag/AgCl electrodes.

Dehydroascorbic acid + 2H⁺ + 2e^- --> ascorbic acid + H₂O (E^o = 0.390 V)

Using E^o = 0.767 V for the Fe³⁺/Fe²⁺ couple, calculate the cell voltage when 5.0, 10.0, and 15.0 mL of ascorbic acid have been added.

Correct answers are: 0.570 V, 0.307 V, and 0.184 V but not sure how to get there

(i) Write S, T, and V using symbolic notation.

(ii) ComputeS∩T, S∩V andT∩V and give symbolic representations that do not use the symbols S, T, or V on the right-hand side of the equals sign.
