Almost ALL of Sam Lloyd's puzzles and their solutions are in the public domain, i.e., on the Internet!!!

Here is this question and one solution: https://www.mathsisfun.com/puzzles/our-columbus-problem-solution.html

Oh alright sure ok have a good day!

I've got to go now,NSS....but...I'll come back later and show you the general proceedure.....!!!

can you show how you got them both?

Well....if I keyed everything in correctly....

Variance  = 2056.52

Std Dev   = 45.35

EDIT to correct an earlier error....

HAPPY EARLY BDAY SYNTH!!

OK, thanks...I'll have to take your word for it....LOL!!!

Thanks!!

happy b-day!! 

Congrats. That is exactly the monthly payment and the total payback.

congrats man 

Yes, that is the correct answer.

Happy B'Day, Synth  !!!!

Answered the first one in your other post

x^4 + 3x^2 - 4     factors as

(x^2 + 4) ( x^2 - 1)  =

(x + 2 i) ( x - 2 i )  (x + 1) ( x - 1)

x^3 + 4x^2 -9x - 36     we can factor this ( by grouping ) as

x^2 ( x + 4)  - 9(x + 4)   =

(x + 4) ( x^2 - 9) =

(x + 4) ( x + 3) ( x - 3)

So...the second, third and fifth answers are  correct...!!!!!

Is the answer $3799.20?

I'll give this my best shot...although I'm not sure of the answer

m = .08/12 = (1/150)

P = $3500

n = 2 years

a  = 12 payments per year

So...the monthly payment is

3500(1/150) [ (1 + 1/150)^(12 * 2)] / [ (1 + 1/150)^(12 * 2)  - 1 ]  ≈ $158.30

If this is the monthly payment...then the total payment is  24 * 158.30  = $3799.20

[ If anyone  else is more familiar with this....please point out any mistakes !!! ]

Welcome !!!

6* 10^(-8)  + 7* 10^(-5)  =

.00000006  +  .00007  =

.00007006   =

7.0006  x 10^(-5)

13*10^-5
