From being called an Archimedes’ Constant to becoming the modern-day “pi”, π has certainly come a long way. The complex nature of this number or mathematical constant charms everybody even in modern times; it is used in a variety of situations and not just as a relationship defined between a circle’s circumference and its radius.

Company A: Let the cost prior to discount be represented by x. Company A offers a discount of 10%. 10% of x is the discount. It is derived at by product of x and 10/100(0.1).Therefore 0.1x is the discount. The cost subsequent to

In any distribution, outliers tend to pull the measures of central tendency with them. Depending on the type of skewness, outliers can either pull up or drag down the mean. Extremely high values pull the mean up while very low values pull the mean down. Outliers result in negatively or positively skewed distributions.

2. The equation gives the approximate distance, D, in miles that a person can see to the horizon from a height, h, in feet, assuming there are no obstructions in the way and accounting for atmospheric refraction.
‘x’ and ‘y’ so that h(x) = y = (7 - x) / 3 becomes x = (7 - y) / 3 and upon arranging the equation, this makes 3x = 7 - y. Getting ‘y’ by itself on one side, y = h-1(x) = -3x + 7.
