1. ### Is there any wrong in this question statement?

In 8 years, amount becomes 17 times of P. So in 15 years, amount becomes how much? A) This is the shortcut: \large \frac{8}{?} = \frac{17-1}{n_{2}-1} â†’ \frac{8}{15} = \frac{16}{n-1} â†’ n = 31 \; times Is there any wrong in question: Is it amount becomes 17 times of P or P becomes 17...

6. ### Is This A Statement About Probability That Is Always True?

If there are x trials, the same x possibilities for each trial, and the probability of each outcome on each trial is 1/x, what is the probability that x trials will have each outcome happen once. Am I correct in saying that it is x!/(x^x). It works for two coins, where the probability of one...
7. ### Is it a true statement ?

9. ### Use proof by contraposition to prove that the following statement

Hi, can someone please help me out on this, it's been driving me crazy for 2 days. The question is Use proof by contraposition to prove that the following statement is true for all positive integers n. If 5(^n) âˆ’ 4 is prime, then n is odd. I've used contraposition to change the...
10. ### Interpreting a statement f(x,y)

f(x,y) = a function in x and y so for a circle f(x,y) will be plotted on the x,y plane. However sometimes at school a function f(x,y) = function in x and y is sketched on the x,y and z axis. Is there a detail i am missing? I can't picture this in my mind.
11. ### How to write a statement

I have a problem So my variables will be Y = Youngest M = Second youngest (middle) O = Oldest T = Total I know so far T = 54000 Y = M x 2 O = (M + Y) / 2 How do I write this so the state ends = 54000? Or am I really trying to find the value of M to solve this?
12. ### Need help in proving that this statement is valid.. (for propositional logic)

Hi guys.. good day. I was tasked to prove that this statement is valid using Chain of Reasoning, Proof by Contradiction, and Proof by Resolution: (Q â‡’ P) â‡’ P (Q â‡’ Q) â‡’ S (S â‡’ R) â‡’ ~(R â‡’ P) âˆ´ S However, I'm having a tough time in doing so, as I am stuck on simplifying...

One of the judges for the Math Art show asked me to clarify or strengthen the math behind the art. Maybe someone can help me with this? I was thinking that this might be the Galileo paradox but unsure. Well, if you can then let me know; thanks! "An infinite amount of radii in any circle...
17. ### Is there a statement equivalent to its own converse?

I know of a lot of pairs or sets of mathematical statements that are equivalent to each other, e.g.: Pasch's axiom and the plane separation axiom, the different statements of the axiom of choice, Playfair's axiom and Euclid's fifth postulate. That got me wondering, is there any mathematical...
