A: ### Quick Answer

**The number Pi, symbolized by a Greek letter, has a constant value that approximately equals 3.14159.** Pi is an irrational number, which means it cannot be expressed as a common fraction, and it has an infinite decimal representation without any repeating pattern.

Pi, by definition, is the ratio of a circle’s circumference to its diameter (Pi = C/d). This constant is used to solve the area of a circle, with the formula “Pi r squared” or “the product of Pi and the square of the length of the radius.” The rounded-off version of Pi is accepted for general computations. Here’s Pi up to 20 decimal digits: 3.14159265358979323846.

## What is a cumulative binomial table?

A:A cumulative binomial table is used in statistics to calculate the probability that the value of a random variable falls within a specific range. Often used to solve binomial distribution problems, cumulative binomial tables usually refer to the probability that the value of the random variable is less than or equal to a specified value.

## What is the formula for linear interpolation?

A:

Full Answer >**The value of y in the linear interpolation equation is defined as a sum of y0 and the product of y differential (y1 – y0), multiplied by the ratio between differentials of x ((x – x0) divided by (x – x1)).**This is a method of calculating the unknown value of y for any given x on the interval between two known points with coordinates (x0,y0) and (x1,y1).Filed Under:
