Question 166726: The management of White Industries is considering a new method of assembling its golf cart. The present method requires 42.3 minutes, on the average, to assemble a cart.
The mean assembly time for a random sample of 24 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes.
Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?

x^2-2x-3=2
x^2-2x =5
x^2-2x+1=6 completing the square
(x-1)^2=6

the sum of an infinite geometric series with first term a and common ratio r<1 is given by a/(1-r).
------------------------------------
the sum of a given infinite geometric series is 200, and the common ratio is 0.15. What is the second term of this series?
Solve:
a/(1-r) = 200
a/0.85 = 200
a = 170 (that is the 1st term)
----
2nd term: a*r = 170*0.15 = 25.5

PS Use * for multiply. x is often used for other things.
And, ^ is used for exponents, or powers.

Question 525854: What are Roman Numerals And what do they do in a Math problem?

It's an unsuccessful, clumsy and obsolete method of counting, and should be forgotten.
-------------
And what do they do in a Math problem?
I don't know what you mean by that.

You can put this solution on YOUR website!
basically they are the numbers romans used
It goes...
I
II
III
IV
V
VI
VII
VIII
IX
X
Ecetera. so I=1 V=5 X=10 L=50 and it depends on what you are working on

Question 399887: what is the answer in roman numeral form 197,631,204
You can put this solution on YOUR website!
197=CXCVII
631=DCXXXI
204=CCIV
Check: There is a good explanation of this in Stan Gibilisco's "Algebra Know-It-All"

Question 396281: how do u figure out how to do roman numerals
You can put this solution on YOUR website!
There are seven of them to remember.
1=I
5=V
10=X
50=L
100=C
500=D
1000=M
Use as few symbols as possible to build each number.
Example:
I,II,III,IV,V (1,2,3,4,5)
Once you get to 4, you write IV meaning V take away I. You do this instead of writing IIII to save space and avoid confusion. The same rule applies at 9, IX means 10 take away 1. Of course 6,7,8 are VI,VII,VIII, and their form means 5 plus 1, 2, and 3 respectivly.
Example:
X,XX,XXX,XL,L (10,20,30,40,50)
Again, start using the shorter script at 40. XL means 50 take away 10.
XX,XXI,XXII,XXIII,XXIV,XXV,XXVI,XXVII,XXVIII,XXIX are the twentys, again demonstrating the rules for making roman numerals.
Example:
C,CC,CCC,CD,D (100,200,300,400,500)
Symbols in roman numeration change to the "take away" form every time 4 and 9 come up.
My book calls it a "kind of" base five system.
My book shows no symbol for 5000 however.
Build hundreds like this:
534: DXXXIV (D for 500, XXX for 30, IV for 4)
Build thousands like this:
3564: MMMDXLIV (MMM for 3000, D for 500, XL for 40, IV for 4)
I hope that got you at least started.

Question 421922: how can you fine the plane
You can put this solution on YOUR website!
Planes are determined by three points on a flat surface.
A plane is found by solving three linear equations in three variables.
This is also known as solving equations three by three.

Question 284499: write an equation to represent
x increased by 50 is 72
a score of at least 90 on the test is considered an "A"
two times a number n plus 3 is at most 5

You can put this solution on YOUR website!
Something or other plus 50 is 72?
Then x + 50 = 72
Check it by subtracting fifty from both sides.
x = 22
That's if 50 plus 22 is 72.
It is.
OK, I'll do the other two even though there's only supposed to be one problem per question.
A is greater than or equal to 90% questions correct.
You'd have to write A is greater than or equal to 90 using > with a line under it.
2n plus three is at most five. That means its less than or equal to five.
2n + 3 is < or = 5
