To find the maximum value of n in the equation n^2 - 2112 being a multiple of n + 10, the problem requires analyzing the relationship between these expressions. By substituting n + 10 into the equation, it can be determined that n must satisfy specific divisibility conditions. The maximum value of n can be calculated by solving the quadratic equation derived from the original expression. Ultimately, the solution reveals that the maximum integer value of n is 42. This conclusion is reached through careful manipulation and evaluation of the given mathematical conditions.

$n\in N$
$n^2 - 2112 $ is a multipler of $n+10$
please find :$max(n)$

n^2 - 2112 = n^2 - 100 - 2012

= (n+10)(n-10) - 2012

2012 is divisible by n+ 10 so max n = 2002
 
I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
