"The set of natural numbers less than 2 express the set of natural numbers less than 2 in roster form"   Gabby, I'd like to help, but I'm confused. What is your question?

Theresa, you wrote the initial factored problem as P(x) = −1/3 (x+3) (x+1) (x−1) (x−2).   In order to "state the 'zeros' of the function," we have to see what values of x will make P(x) = 0.   Each of the elements are multiplied, so if...

I borrowed this answer from Wikipedia. I could not word it better myself, but it explains how confounding variables work: As an example, suppose that there is a statistical relationship between ice-cream consumption and number of drowning deaths for a given period. These two variables have a...

Jenna,   The question of "cups" in this story problem is NOT the same as "cups" in American Standard Measurement. Remember to keep you units in Metric, and your solution will be very easy to find.   You were correct, too, that it IS Metric conversion,...

I suggest you view this website: http://www.umuc.edu/writingcenter/onlineguide/chapter2-01.cfm. Look at page 4 for targeting your audience.   In addition, remember the purpose of your writing. If you are going to make any statistical declarations, you must include data from a control...

I hope I understand your question correctly.   The 4 angles of a quadrilateral add to 360o. (Property of quadrilaterals.)   If you add 6x+4x+5x+3x= 360o, then 18x=360o, and x=20.   However, if you are looking for an x value in a coordinate plane,...

You have to use the trig functions sine, cosine, and tangent to solve this. (SOH CAH TOA: Sin = opposite/hypotenuse; Cos = adjacent/hypotenuse; Tan = opposite/adjacent.) Trig functions are ratios of side lengths, see above, as compared to an angle that we call theta Θ.   If...

This is a monologue.   Watch an episode of Saturday Night Live. At the beginning of every episode, the guest gives a monologue of about 2 minutes.   Hope that helps!

Kirill and Felice gave good answers, but I wanted to add this to eliminate any confusion.   We can only use trig functions with right triangles, so you have to use Pythagorean's Theorem to solve for the hypotenuse: a2+b2=c2. a and b = 4 and 11, in either order, according to the...

Ryan Y. gave a great answer! I just wanted to add that  you can use the Poisson Formula. (Yes, I know poisson=fish...) If you need to look up how he did his data, that's the name to use.

weight (American): oz (ounces), lbs (pounds), tons weight (metric): grams volume (American): tablespoon, teaspoon, oz (fluid ounces), cup, pint, quart, gallon volume (metric): litres or cubic centimeters (cc's) count.....? legth (American): inches, feet, yards, miles length...

(1/3)*(3.14)*2*sqrt(6)*4 = 20.5 Order of operations does not aply here since each factor is being multiplied.

If you can give an example from the book or worksheet, it will be much easier to answer your question. I also have not heard the term "6 moves long," but I think it might relate directly to a classroom activity, not necessarily a common math term.

counterexample (answer)

Julie, you will see the term "counterexample" throughout the year. It means to provide an example that proves the hypothosis false. For example, "All bunnies have ears. Fluffy has ears. Therefore Fluffy is a bunny." The counterexample is that fluffy could be any animal with ears...

You can also learn the quadradic formula. It will never let you down, and you have to learn it eventually. :) Check out the video on you-tube for a memory trick/song. http://www.youtube.com/watch?v=CnJT1ojHT28 ; (jingle bells tune)

Converting between units can be challenging because it doesn't really make sense. When you convert feet into yards, like Elisha said, you will DIVIDE BY 3. However, when you convert feet into inches, you will MULTIPLY BY 12. The part that confuses people is when to multiply and when to divide. Imagine...

ajacent angles (answer)

I added a link to clarify "adjacent" angles, as well as other angle relationships. Hope that helps. (It has pictures and definitions.) http://www.mathsrevision.net/gcse/pages.php?page=17

2x - 3y = 10 + 3y + 3y (add 3y to both sides) 2x = 10 + 3y 2x/2 = 10/2 + 3y/2 (divide each coefficient by 2 to isolate x) X = 5 + 3/2 y (this is the SIMPLIFIED answer for X) ---or if you are solving for 'y'--- 2x -3y = 10 - 2x - 2x (minus 2x from...
