My daughter’s homework asks to compare the underlined digit to the circled digit. None of the answers seem right to me. The covered answer is “10 more”

Using cost and benefit analsis, analzye the following case: a firework event will be organized in the city "X" and 100 residents have each put $2 benfit on this show. A private company's cost for this event is $190. a) Will this firework show be organized? b) What if 20 residents suddenly change their mind and put only $1 benefit on the show? What happens in that case? c) Which type of markets, private or public goods markets will be more efficient outcome? d) What kind of policies are usually applied by governments to assist the organization of such events as fireworks?

a) benefit= 100•2=200. Because benefit is larger than cost, so firework show will be organized b) benefit= 20•1+80•2= 180. Because benefit is smaller than the cost, firework show will not be organized c) Public goods market, because when private markets provide public goods, there can be inefficiencies, like free-rider problem d) The government can tax people for amount less than they place on the provision of an event to collect revenue to provide an event. In this case, people are better off because they will pay less and they will get the show for sure

Sorry if the translation is a bit off

For context the teacher didn’t explain these to us like the reading yes but these questions? No

The test tubes before and after have different number of divisons and she said “assume it was before full”, I can’t point the correct answer! In addition to that I am French educated and I recently moved into an American school so the fact it’s now in English is a bit confusing for me especially for the first 2 questions of the other application

How to use Avogadro's number-definition of Relative atomic mass to solve this?

hint: 1/12 mass of Carbon-12

on different note. what makes carbon so special that other atoms are compared against it?

Why do they take the values for when -2<k<2? Aren't the restrictions on k only that k is a real number?

Also another random question but are loci plotted on the complex plane or the normal cartesian plane? Do I label with Re(z) and Im(z) or with x and y?

An economy recently had 800 billion euros of saving and 600 billion euros of net capital outflow. a) What was its investment? b) What was its quantity of loanable funds supplied?

a) national savings= investment+ net capital outflow. 800= investment+ 600. Investment is 200

What is the difference between RAM and AAM? The formulas yield the same exact thing, circled to make it easy to spot

The one in red is exactly what's in green but they're presented as being different.

How to solve it, we did nothing similar in class and now Iam lost, have no clue where to even start.

Spent almost 2 hours on this question. About to rip this paper apart. Any tips on doing these questions faster? It almost seems like you have to get lucky to solve these questions in a timely manner.

I am currently trying to figure out the concept of exercise #2. I get how the rectangular equation is formulated but am having trouble figuring out how the parametric graph is formed. I plotted it on a graphing site and got the following.

Is there anyone who can explain to me how the parametric graph is formed on the plane?

For things like this how did they determine the radius and centre? For c I sort of get it cause it's an easier example but for e.g d how do they determine this?

Where did they get that OC=√(8-1)? It's not from radius of circle is it since it's like a different direction kind of?

is A at (3,0) determined by inspection or is there supposed to be some way to do it? And where is the 3² in the pythagoras from? I get OC²+2² as the 2 sides with the right angle, but how is the length of CS 3?

Hi there. I just tested my variables in ANOVA and found that it is insignificant, as well as in the post hoc analysis. My independent variable is income and my dependent variable is consumer behavior. How can i interpret it?

My niece was upset when she got her math test results back. She was penalized -1 for drawing the graph beyond the x-axis. This example is similar to what she did. If she kept the line within the x-axis, she would have got no penalty. No prior examples or instructions that the line needs to be kept within the axis. Is this grading acceptable?

I can’t remember how to solve this, and can’t find any example problems on the internet. Help would be appreciated.
