<em />I did this in my head; it would take longer to write it out. I'll show you the trig if need be.
8-5=3
19-11=8
3/8=0.375
Rate of Change: 0.375
States that the sum of any 2 sides of a triangle must be greater than the measure of the third.<span />
P(<em>Z</em> ≥ <em>z</em>) = 1 - P(<em>Z</em> ≤ <em>z</em>) = 0.06
==> P(<em>Z</em> ≤ <em>z</em>) = 0.94
==> <em>z</em> ≈ 1.7507
