What is a Bar Model in Math? A bar model is one such tool that helps us visualize the given math problem using different-sized rectangles or bars. The size of the bars are proportional to the numbers that it represents. Let’s take up some bar model examples to understand them better....
Solution: 104/146 as a decimal is 0.71 Methods Explanation using the division method: A fraction is usually split into two parts: the first part is the number on top, called the numerator; and the second part is the number on the bottom, called the denominator. These are both separated ...
Thisbinary entropy functionis depicted in the figure below (random variable can take one of two values). It reaches its maximum when the probability isp=1/2, meaning thatp(X=a)=0.5or similarlyp(X=b)=0.5having a 50%/50% chance of being eitheraorb(uncertainty is at a maximum). The ...
What Is a Harmonic Mean? In addition to the arithmetic and geometric means, theharmonic meanis calculated by dividing the number of observations by the reciprocal (one over the value) of each number in the series. Harmonic means are often used in finance to average data in fractions, ratios...
