1 Merino is one of the softest types of wool available, because of finer fibers and smaller scales.  Merino has an excellent warmth-to-weight ratio compared to other wools, in part because the smaller fibers have microscopic cortices of dead air, trapping body heat similarly to the way a sleeping bag warms its occupant.
Transistorâtransistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT) and resistors.
Report Abuse. The relative frequency of a particular category is the proportion of observations that fall into the particular category. The cumulative frequency (or proportions) is addition of the frequencies in each category from zero to a particular category. If your chart is a histogram, the proportions (areas) of all the bars should add up to 1. There is no practical equation, it's just a matter of counting.
