combinatorics
The number of bacteria in a culture is 1000 and this number increases by 250% every two hours. How many bacteria is present after 24 hours?
probability
A hypothetical example: You have a 1/1000 chance of being hit by a bus when crossing the street. However, if you perform the action of crossing the street 1000 times, then your chance of being
How much zeros has the number $1000!$ at the end?
1 the number of factor 2''s between 1-1000 is more than 5''s.so u must count the number of 5''s that exist between 1-1000.can u continue?
elementary probability
A big part of this problem is that the "1 in 1000" event can happen multiple times within our attempt. Compare this to if you have a special deck of playing cards with 1000 cards in it, exactly
Why is kg/m³ to g/cm³1 to 1000?
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
How many digits does $2^ {1000}$ contain?
For a quick back-of-the-envelope computation, you can note that $2^ {10}$ is only a little larger than $10^3$, so $2^ {1000} = (2^ {10})^ {100}$ is larger than $10^ {300}$, though not by much; so $2^
What Will a 1000W Solar Panel Run?
A 1000W solar panel system, often considered a baseline for residential solar energy projects, signifies the system''s capacity to produce up to 1000 watts (or 1 kilowatt) of power under

What does the sum of all the numerals from the numbers from $100$ up to $1000$ equal to?
Differential equations : A tank contains 1000 L of brine
A tank contains 1000 L of brine (that is, salt water) with 15 kg of dissolved salt. Pure water enters the top of the tank at a constant rate of 10 L / min. The solution is thoroughly mixed and
Creating arithmetic expression equal to 1000 using exactly eight 8''s
I would like to find all the expressions that can be created using nothing but arithmetic operators, exactly eight $8$''s, and parentheses. Here are the seven solutions I''ve found (on the Internet)...
algebra precalculus
Given that there are $168$ primes below $1000$. 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
How much electricity a 1000 watt solar panel can
When you use a 1000 watt solar panel, you can expect it to generate between 4 and 6 kilowatt-hours (kWh) of electricity each day. This range comes from real
