19. Amanda exercises by swimming each month. She does not want to swim more than seven times in a month. She swims exactly seven times a month 15 % of the time, swims six times in a month 10%, five times in a month 40%, four times in a month 5%, three times in a month 5%, two times in a month 5%, once a month 10% of the time, and zero times in a month 10% of the time. Through observation, she has established a probability distribution. A. Summarize the probability distribution function in a table. B. What is the expected value of Amanda swimming? Show your work. C. What is standard deviation? Show your work. D. Find the probability that Amanda swims more than 4 times a month. E. Find the probability that Amanda swims more than less than 3 times a month.

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
