Hey Everyone,

Since we seem to have a few nibbles of interest in another thread, how about a thread in which math problems are presented for other users to solve?

All are welcome to answer, whether you show your work or not, but I would like to ask that for those who can, please show us how you came up with your answer so that the rest of us can learn. :)

We'll see how it goes. When one problem has been answered several times, maybe we'll then try opening the floor to present another problem. Hopefully this will be a bit of a challenge as well as some fun for all you mathematically gifted folks. :) As I said in another thread, I love the idea that some of the God-given skills others may have made fun of some of you for... Are considered totally cool here!

I hope we all have a great time in this thread!

Our very own MollyConnor has generously provided us with the first problem:

Here is a story problem. Have fun y'all!

Kathy's Kandies features a mixture of chocolate creams and chocolate-covered caramels that sells for $9 per pound. If creams sell for $6.75 per pound and caramels sell for $10.50 per pound, how much of each type of candy should be in a 1-pound mix?
And, to get this party started right, I'll end this first post with a math pun:



(This pun kind of reminds me of all my OP's... :D)

Thanks for participating and I'm looking forward to learning some amazing things!!

Oh, good. Can somebody explain to me why at the end of an exploratory factor analysis it turns completely theoretical and I can just name the latent factors arbitrarily? I'd really like to know so I can discuss it in my lit review. I'd be happy to share my data, provided you use "R" as your Statistics analysis tool, and you can see what kind of magical unicorn bull-crap I am dealing with. The variables load clean, I have parsimony, the reliability and Cronbach's alpha look AWESOME, but why am I able to just pick a name for the factor and discuss it like it ain't no big deal?

Okay, okay...not derailing.

Give an example of a function that is defined everywhere on the number line, yet is never continuous.

*hint

X = if,

X = if,

Think of the difference between rational and irrational numbers.

Judging from these first two posts...

The first thing I'm going to need in this thread...

Is a good translator.

As much as I like to market myself as someone who understand mathematics, I have a minimal understanding. I struggled with them in primary and secondary school. College is when they made sense to me and I understood that the only reason a person needs to learn Algebra is to navigate Calculus. When I was married to my first wife, one of her friends was married to a professor in the Physics department at ISU, and he was more than willing to talk about his work, which was highly theoretical, and he would walk me through his calculations. It helped that he was a major Linux nerd, so we had a few things in common. Between my coursework, my relationship with that guy, and my graduate studies, I've learned to appreciate math, but I still think it sucks the big one. I can do some fairly high-level math, but I am not a mathematician by any means. I just appreciate it for what it is. It kind of makes sense to me.

I would like to add that the above is an Algebra I problem. So it's a bit challenging but nothing super hard either. In other words, you have to use X. :eek:

The problem does not specify what the answer should be. Are we looking for a percentage of total, or are we looking for ounces?

Either way it's going to be moot, because I'll eat up all the chocolate creams AND all the chocolate caramels. A bag of Riesen doesn't last long around me. :D

Anyway, the ratio is two to three, creams to caramels. For every two creams in the mix, three caramels should go in the mix. Or the resulting mix in a pound should be two thirds of a pound caramels, one third of a pound creams.

I didn't use algebra though, I used the difference between each of the candies and the total. The difference between $6.75 and $9 is $2.25 and the difference between $10.50 and $9 is $1.50. So the ratio that should go in the bag reflects the difference in price between each of these and the desired total.

$2.25 against $1.50
Divide each by 75 reduces to
3 against 2

A very unprofessional approach, but I got the right proportion of creams and caramels in the bag. Now gimme candy!

Ok Molly, I hope you have the answer handy so u can verify that this is correct... :rolleyes:

I used the allegation method.. I can't type it out because its a tic-tac-toe diagram. :p

Answer is:

9.6oz. of the $10.50 caramels

and 6.4oz. of the $6.75 creams

totalling 16oz. (1lb)

Yes its english lol. Its what we use when we have to mix 2 different strength medications to come up with a specified strength. Like if the doctor ordered a 50% solution and we only had on hand a 20% solution and a 70% solution.

And 6.4 over 9.6 equals... 2/3. :cool:

I have a numbers problem but I've already run it here on the forum before so somebody with a good memory would solve it right fast.

I hate to be that guy, but you put in half a lb of each.

6.75/2= 3.38
+
10.50/2= 5.25
. 8.63 . 9.00-8.63= $00.37 extra profit. This is a business, not a charity. ;)
