The mathematical operation “n choose r” denotes all ways of choosing r elements from a set of n elements. For example: ExpressionResultExplanation4 choose 41there is 1 way of choosing 4 items from a set of 4 (take them all!)4 choose 14there are 4 ways of choosing 1 item from a set of 4 (pick one!)4 choose 26there are 6 ways to choose 2 – try it4 choose 34there are 4 ways to choose 3 – try it3 choose 40can’t take 4 items from a set of 3 Write a recursive function called choose which takes as input two integers, n and r, and returns the number of possible ways of choosing. Hints: To choose 3 marbles from a collection of 5, decide if the first marble is “in” (part of the chosen set) or “out”. If it is “in” then recursively choose 2 more from a collection of 4. If it is “out” then recursively choose 3 from a collection of 4. Combine these two scenarios to form the recursive case.Consider the possible base cases - there are more than one! Declare and implement a recursive function to display a decimal integer (i.e. base 10) in binary notation. It should have the following signature in recursion.h: void show_as_binary (int n); The iterative solution to this function might be something like: void show_as_binary (int n) { int bit = 0; string bin = ""; while (n > 0) { bit = n % 2; n /= 2; bin = to_string(bit) + bin; } cout << bin; } However, the recursive solution does not need a string accumulator - you can cout the bits directly.

What do sociologists mean by "welfare policies" and "welfare states" or "the welfare state"? Select any or all of the statements below that give correct answers to this question. This test question doesn't offer you slides. You are encouraged to think across units and concepts that you've learned in Intro to Sociology. Of course, you're welcome to look up whatever you'd like, if time permits. Question 1 options: U.S. Tea Party activists' paraded in support of Democratic president Barack Obama's effort to expand the U.S. welfare state with greater medical coverage for low cost or no cost. Finland and Norway are examples of small countries yet with relaively big welfare states. Welfare states sometimes are funded with higher tax rates on rich people in a society. To the extent people with higher incomes are made to pay higher tax rates, social scientists call this progressive taxation. Modern welfare states use taxes and transfers to relieve poverty in various ways, to varying degrees among the rich democracies. The USSR under Stalin, was a capitalist welfare state that competed with negihborhood co-ops.

give a guide on how to find the output of an LTI system given an input or another output. Also provide an answer to this question: For an input x(t) = u(t), the output of an LTI is y(t) = [1-e-2t] u(t). What is the output of the LTI if the input is 4[ u(t) - u(t-1) ]

Objective: Use wildcards to search for files and directories. Description: In this activity, you use the common wildcards * and ?. You also see the results of more uncommon wildcards. 1. If necessary, start VMware Player and start an openSUSE virtual machine. Log in to openSUSE as a user other than root, and open a terminal window. 2. Use the absolute method to change to the /etc directory by typing cd /etc and pressing Enter. 3. Display a long list of files and directories in the /etc directory by typing ls -l and pressing Enter. 4. Display a long list of files and directories in the /etc directory starting with the letter "h" by typing ls -l h* and pressing Enter. How are the results different from Step 3? 5. Display a long list of files and directories in the /etc directory and use two wildcards by typing ls -l *.2 and pressing Enter. How are the results different from Step 3? 6. Display a long list of files and directories in the /etc directory starting with a, c, or k by typing ls -l [ack]* and pressing Enter. 7. Display a long list of files and directories in the /etc directory starting with a, b, or c by typing ls -l [a-c]* and pressing Enter. 8. Display a long list of files and directories in the /etc directory that don't start with the letters a through s by typing ls -l [!a-s]* and pressing Enter. 9. Change the current directory by typing cd /h* and pressing Enter. What happened, and why? 10. Leave the terminal window open and the virtual machine running for the next activity.
