That's what I was looking for. Thank you very much.

Thank you very much, drwls. I actually understand it now! (You saved me in Calculus!) :-)

The student is correct because the median is used to find the middle numeric value of a data set, the mean balances out the data so all numbers in a data set are the same. This means that the mean and median can only be used for a numeric data, so this student is correct.

thank you very much Ms.Sue!!!!!!!!

you're very welcome!!!!!

i ment what is a number that divied by 3 has a remainder of 2 also that same number divided by 4 has a remainder 3 and that same number divided by 5 has a remainder of 4

Thank you very much! It conveys exactly what I was trying to say.

Thank you very much.

Thank you Ms Sue.

Thank you Ms. Sue. You really helped me.

i have a question with my algebra hw about (7Xto the6*ytothe9)to the4/3xtothe 10*y to the 4

no the second one left a half an hour later sorry i forgot to include that

564t=744(t-.5) 564t=744t-372 564t-564t=744t-372-564t 0=180t-372 0+372=180t-372+372 372=180t 372/180=180t/180 2.07=t Is that correct?

ok thank you for all of your help

false, has to be connected to the internet

i got 14

wHAT DO I DO WITH THESE VALUES THEN...

Area of the house to be painted = A Bill pains "B" area per hour John pains "J" area per hour So, A/B = 4 hours, and A/J = 7 hours => B = A/4 and J = a/7 B and J says how much area they can paint per hour. When both of them work together, assume it takes x hours to finish the work => xB + xJ = A the total area painted x(A+B) = x(A/4+A/7)=A x (1/4+1/7)= 1 so x = 28/11

Are you sure you wrote the question correctly? I do not understand how g which is a function of x is written as a function of t, and especially with the dt.

dD/dt = A(2pi/365)*cos [(2pi/365)*(t-80)] =0 for maximum or minimum (2pi/365)*(t-80) = n*pi/2 when n=1 gives maximum , then (t-80) = 365/4, for minimum n = 3 and t-80 = 3*365/4 (3) = dD/dt = +2/60 (4) = dD/dt = -2/60

Our teacher told us that the fourth partial sum approximates the sum of the sequence 7n/(n^3+1). The fourth partial sum is also the error of the sequence and our teacher asks us to find a number X such that the error is less than X.

plot it on a graph in your calculator. then see the number where the line continues to stay on for a y value. for example, lets say it will go up and down but when it hits x=4 the y value is 2 and every y value after that is 2, then the limit for infinity would be 2. also...for b, to estimate the limit show really large values and show how their y values are all the same because the limit will stay the same as x will approach an infinite listing of numbers

Ok, I got that, but what do I do with the 3.16 ×10^23?

so it would be 6.02 x 10^23 x 50? then whattt?

Totally lost.

thanks

Is there anyway you could work this one out for me and explain what you did? I would probably learn a lot better than all of this reasoning and proportions. It's greatly appreciated.

ahhh, I get it now. thanks a lot, I actually did learn how to do it now, believe it or not.

WITH A(0,2),B(6,2)AND C(4,4) APPLY THE RULE (1.5X,1.5Y) TO THE VERTICLES OF TRIANGLE ABC TO GET TRIANGLE PQR. COMPARE THE CORRESPONDING MEASUREMENTS(SIDE LENGHTS,PERIMETER,AREA, AND ANGLE MEASURES) OF THE TWO TRIANGLES? THIS IS THE 1ST QUESTION OF 5 I HAVE TO DO, AND I DON'T UNDERSTAND, PLEASE HELP!P.S THIS IS A GRAPHING QUESTION

No,you can also multiply.

our cat katie usually drags its food out of the dish when its happy -Capital at the beginning of the sentence -Comma after cat -Capital for the noun's name -Apostrophe on both 'its' to show posession -Period at the end of the sentence so: Our cat, Katie usually drags it's food out of the dish when it's happy.

Neither sides are involved in a war perhaps.

if you are using APA, then its the (author, p. 4-9) I believe.

If 12.5 mL of 8.6 multiplied by 10-2 M NaOH is added to 32.5 mL of 6.0 multiplied by 10-4 M NaOH, what is the pH of the solution?

pH = .5 (pka1)

can you write me some kind of a equation or explain to me in a way which i can understand. because what they wrote is just flying over my head and i have already spent a good amount of time trying to figure these out. so please help

nvm i got it, thanks for the help guys.

It would be 2pi/6 because period (1 oscillation) = 2pi/b

momentum is p=mv so p(brother)=(35.6)(9.50)and p(skateboard)= (1.3)(9.50) solve and add them.

ok formula L=Iw i know I=5kgm^2 and i am finding w. How would i go about finding L give me a hint.

I do not see how Reiny went from: cosx(2sin^2x-1)/sinx TO (cosx/sinx)(-cos2x) if you break it up you get (cosx/sinx)((2sin^2x-1)/sinx) help im doing a take home exam lol

still questionable not understanding how to get the problem with the correct answer

httth

It should be D. If the hypotenuse and leg of a right triangle are congruent to the hypotenuse and leg of another right triangle, then the triangles are congruent

Thank you Jen. U r great

Yes, thank you. I was doing it that way, but didn't know if I was correct.

I agree with SraJMcGin, that will give you the answers.

so than... 70's to 80's - 265000 increase 265000/124000=2.137= 213.7% Right?

how did you get 114???

just wondering...

i'm guessing to Megan that it is 717.7%???

the percent i think is because in the early days the price wasn't that high or expensive as today. my bad, heres my other, i think, ummm.... to start 10000 so if you add 10000 to 25000= 35000 then, 35000+89000=124000 nest, 124000+265000=389000 i'm guessing the total will be 540000???

man than i must such at math than...oh well sorry megan .

no really were all just in the library helping each other get ready for a bug chem test

The example we were given was - He was a fine doctor, but he was growing old. My assignment was to find 5 sentences that use this pattern.

Thanks for your help.

2a) (4,1)x(4,4)/ (8,5)=4/56 For 2a, why is student 4,4? I don't understand that. I know that for 1 teacher, there is 4 student because there is 5-person committee. I don't know question b.

So, for b it is (4,3)(4,4) + (4,2)(4,1)/(8,5)= 28/56= 1/2?

If possible, can you help me with this question also? From a group of 10 girls and 10 boys, 10 will be chosen to form a committee. Find the probability that atleast ONE GIRL is chosen. I did it like this At least 1 girl so therefore I separated more than 1. -------------------- 0 |1 2 3 4 5 6 7 8 9 10 n(Zero girl)= (10,0)x(10,10) = 1 n(atleast 1 girl) = # total possible - (zero) =(20, 10) - (10,10) =184,755 Is this correct? Thank you for helping me!

Thanks! T___T another question (Last one I promise, lol) The probability of a household subscribing to The Economist is 0.4 while the probability of subscribing to National Geographic is 0.6, and the probability of subscribing to NEITHER magazine is 0.2. What is the probability that a randomly selected household subscribes to: a) Either magazine? b) both magazines? I have no clue what formula to use this one...I checked my textbook but I don't know

Thank you! I think I did this before but I forgot... How do you know whether or not to use those formulas in these kind of questions? rearrange formulas? P(A U B) = P(A) + P(B) - P(A and B) and P(A U B) = P(A) + P(B)

Ah, ok thank you!

Do you suggest any other topics that has a lot of information?

second one

Not really having trouble with this one for some reason

6*6+6*6-6=24 Where would the parenthesis go?

Woops sorry and thanks lol

I don't understand? Can you please explain?

What i got was : a) K = (3.0x10^-6)(0.12)/(0.12)(0.12)= 0.6 b) i got 1.90%

i got K= (HOBr2)(OH)/(HOBr) 2.0x10^-9 = (x)(x)/0.18M x= 11x10^-6 (OH-) =11x10^-6 (H3O)= 1.0x10^-14/11x10^-6 =9.0x10^-8

K is the chemical symbol for which element?

Last one. What is the first element on the periodic table? I already answered these questions but I'm making sure they are correct:D Thanks

Because DeVry is asking you this question in this week's discussion...seriously, do the research yourself...see you in the threads!

1/2 is the same as .5 and 50% 2/5 is the same as .4 and 40% fractions, decimals and percentages are all interchangeable, however percentages are generally just used in charts for a marketing group to understand (they like percents better).

metals have lots of free or lose electrons that allows the energy to move freely while insulators electrons are tightly bound and don't allow for lots of energy movement

x^2 +6x+9=24+9 (X+3)^2=33 x+3=sqrt(33) x=+-sqrt(33)-3 or look up Quadratic formula

Thanks-got it cubic trinomial. Here's another one when I have to change signs of negatives and positives for addition and subtraction. How do I do for example 5w^2-4w-7-8w^2+3w-3?

No I do not want the Name I want to know how to figure it out once the numbers are all lined up and it is very confusing when signs need to be switched. Can you please explain that?

Thanks. There was ( ) on the 8 and the rest because your answer is not one of the answers

stratified sampling

Thank you, it worked... I was diving the wrong way

Is this the thesis: "Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe to assure the survival and the success of liberty." ?

Seven was correct. Political culture is defined as a commonly shared set of beliefs and values about politics and government. The culture affects how people believe that politics should be carried out. Most countries have a unique political culture affected by their history and people.

Yeah, what I accidently did was I tried to solve it further, but I completely over thought that. Thank you Bob!

Yeah, I was forgetful and forgot it was the Quotient Rule. Thank you all, I got it!

I believe B is correct :)

I had to miss my last week of Calculus due to some personal things, so I had not been through any lectures of optimization. It hurt me greatly, now I have a few of these that I don't know how to set up at all.

Thx

I know how to solve it to get .21, but I need to write it using positive exponents only. I know this isn't technically Calculus, but it is what we are reviewing currently. I am a bit rusty with this one, can't quite remember how to do it. I am trying some different things, but would greatly appreciate an explanation. Thank you!

That's interesting you say that, listed under my professor's list of things we need to study, he has that listed. Do you believe it to be a mistake? Should I email him perhaps? I see what you are saying here. Thank you Bob.

Actually not because the problem is asking for 3 digits such as 100

Sorry made a mistake you are right
