When more than 12 patients arrive in a given hour, the ER finds itself short staffed. Define a new random variable Y = the number of hours in a day that the ER is short staffed. Describe the distribution of Y.

F(x) = (x^2 + 3x − 4) and g (x) = (x+4) find f/g and state the domain.

Consider the graph of the exponential function y=3(2)×

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
