You invested $2,300 in a stock. your account now has a value of $2,643. your percentage gain on the investment (rounded to the nearest percent) was: a)0% b)5% c)10% d)15%

15℅

Explanation:

Amount invested = $2,300

Present account balance = $2643

%gain on the investment can be calculated as;

Current balance-initial amount invested/initial amount invested× 100%

Substituting the figures given in the formula we will have;

% gain = {$2643-$2300/$2300}×100%

% gain = ($343/$2300)×100%

% gain = 0.1491×100%

% gain = 14.91%

= 15% (to the nearest percent)

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
