“Complex does not mean complicated” (Math is Fun, 2014). Complex means a combination of numbers. These combinations of numbers that form a complex number consists of real numbers and imaginary numbers. The complex number system is an extension of the real number system because it introduces the imaginary number system to the real number system. The complex number system can be visualized in two dimensions and the numbers within the system can be plotted using a Cartesian plane. However, the axes are not exactly the same as a traditional Cartesian plane (x-axis and y-axis). To plot the

For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.

Misconceptions and confusions between the “+” signs and “÷” signs are easy to make when the font size is too small. There was a misconception that led to there being no correct answer for one of the questions.

1. A 95 percent confidence interval estimate will have a margin of error that is approximately + 95 percent of the size of the population mean.

I am confident that my results are correct because when I was doing my research to find the mean of heights of males in the United States, I found similar sites that gave the same mean average. The results of the average mean of males in the US is relatively close to the result I found during my research, which made me feel pretty confident that I was headed in the right direction. To find the standard deviation of heights of males in the US is impossible because you would have to measure everyone’s height, which no one has done before. When I found my confidence interval the values was consistent with the data I collected. Most of the data that I found were between the numbers 68 and 70 with very few of them falling above and below the intervals.

Confidence intervals can be computed for any level of confidence typically, 95% confidence intervals are used to understand population mean (Schindler, 2016). However, confidence levels of 90% and 99% can also be used to decrease or increase the level of confidence (Schindler, 2016). A 90% confidence interval, means that there is a 90% chance the confidence interval includes the sample mean (Schindler, 2016).

In the 16th century of the European nations there were great theories about algebra, they rejected the method that negative numbers could be used in an algebraic equation and many of the mathematicians would quickly accepted zero as a number but

The earliest reference to complex numbers is from Hero of Alexandria’s work Stereometrica in the 1st century AD, where he contemplates the volume of a frustum of a pyramid.

is known as logic gates. There are logic gates: AND, OR, XOR, NOT, NAND, NOR, and

The sample- 200 randomly selected employees from the marketing department from each business selected. Therefore, the total sample would be 600 employees.

(1) A and O as well as E and I both serve as negations of each other

Numbers notation is a way that scientist used to reformat numbers especially, very large numbers and vary small numbers. Numbers notation has many useful properties, so it used by scientist, mathematicians, and engineers. (a x 10^b) is the form of all numbers written in scientific notation ,where b is an integer number , and a is real number . Also, we can read as 'a' times 10 raised to power b. However, any number can be written in scientific notation (ax10) .for any number greater than 1 the exponent b is positive. Otherwise, when number between 0 & 1 the exponent b is negative and it can be written as ( ax10^-b). For example 0.0015 can be written as .5 x 10^-3.
