I would like to find all the expressions that can be created using nothing but arithmetic operators, exactly eight $8$'s, and parentheses. Feb 24, 2023 · Question Statement An investor has $\$20,000$ to be invested amongst $4$ possible investments. Then the sum of all primes below 1000 is (a) $11555$ (b) $76127$ (c) $57298$ (d) $81722$ My attempt to solve it: We know that below $1000$ there are $167$ odd primes and 1 even prime (2), so the sum has to be odd, leaving only the first two numbers. May 13, 2014 · 1 the number of factor 2's between 1-1000 is more than 5's. If all the money needs to be invested then how many investment strategies are available? What if not all the money need be invested? Jan 1, 2018 · Further, $991$ and $997$ are below $1000$ so shouldn't have been removed either. can u continue? Jul 17, 2019 · I understand that changing the divisor multiplies the result by that, but why doesn't changing the numerator cancel that out? I found out somewhere else since posting, is there a way to delete this? A hypothetical example: You have a 1/1000 chance of being hit by a bus when crossing the street. Here are the seven solutions I've found (on the Internet) May 13, 2014 · 1 the number of factor 2's between 1-1000 is more than 5's. This gives $224+2+2=228$ numbers relatively prime to $210$, so $1000-228=772$ numbers are divisible by $2$, $3$, $5$, or $7$. so u must count the number of 5's that exist between 1-1000. Each investment must be a unit of $\$1,000$. May 13, 2014 · 1 the number of factor 2's between 1-1000 is more than 5's.

Feb 5, 2017 · Compute 3^1000 (mod13) Ask Question Asked 9 years, 1 month ago Modified 9 years, 1 month ago Jun 27, 2018 · A big part of this problem is that the "1 in 1000" event can happen multiple times within our attempt. Oct 23, 2016 · The exponent of 13 on the factorisation of $1000!$ is $\lfloor\frac {1000} {13}\rfloor+\lfloor\frac {1000} {13^2}\rfloor$ do the same for $326!$ and $674!$ and you'll find that after dividing the exponent on 13 will be greater than one, so the residue modulo 13 is 0. Compare this to if you have a special deck of playing cards with 1000 cards in it, exactly one of those cards is the ace of spades.
