Begin by writing the corresponding linear equations, and then use back-substitution to solve your variables. 10–1301–8001 159–1 = x-13z=15y-8z=9z=-1 = x-13(-1)=15y-8(-1)=9z=-1 = x=2y=1z=-1 x,y,z=(2 , 1 , -1) Determinants and Cramer’s Rule: 2. Find the determinant of the given matrix. 8–2–12 = 8*2 - (-1)(-2) = 16 - 2 = 14 3. Solve the given linear system using Cramer’s rule.
A VPN. 5. What is the difference between MD5sum and SHA1sum hashing calculations? Which is better and why? One of the big differences is that MD5 uses 128bit and SHA1 160bit for the length, this makes it stronger but slower to generate.

The sampling distribution for the difference in sample proportions has what standard deviation? (a) 1.3 (b) 0.40 (c) 0.047 (d) 0.0002 (e) None of the above. 2. What is the best reason for performing a paired experiment rather than a two–independent sample experiment in this case? (a) It is easier to do since we need
When teaching a student about constructing explanations it is important to understand what the purpose of the explanation is trying to say; being thorough is going to be the best option as the more details that are available the more likely the person reviewing the experiment will understand what was trying to be done. The use of computational thinking requires a student to be logical, this is required to be able to solve problems that are more complicated, it involves many aspects such as mathematics (to solve equations), gathering information from many sources; it also requires that the student be able to understand how to gather information from different sources such as the internet or different scientific books (which can be accessed in many locations
The most common verbs in algebra are = ( is equal to ), < ( is less than ), > ( is greater than ), ≤ ( is less than or equal to ), ≥ ( is greater that or equal to ), ≠ ( is not equal to ), and ≈ ( is approximately equal to ). Some algebraic sentences are A = π r ^ 2, a + b = b + a, and 3x + 9 < 22. Algebra is the study of expressions , sentences, and other relations involving variables. Because many expressions and sentences are based on patterns in arithmetic, algebra sometimes is called generalized arithmetic. Writing Expressions and Sentences From your earlier study of algebra, you should know how to write expressions and sentences describing real situations, and how to evaluate expressions or sentences.
Two real irrationals solutions Two real rationals solutions f(x) has two real rational solutions and and g(x) has two real irrational solutions. After matching these functions, explain to Professor McMerlock how you know these functions meet each condition. Remember, he is a professor, so use complete sentences. When the function crosses the x axis meaning f(x) = 0 there are two real numbers of x that satisfy the equation. Numbers where you can't write them as a fraction, and thus can't write them as a decimal which repeats are irrational.
Composition and Inverse Functions MAT 222: Intermediate Algebra Instructor October 12, 2014 Composition and Inverse Functions Functions are helpful in algebra to determine model dependencies among different variables. For example, some situations require many levels of dependencies and are useful to express the final variable in terms of the first variable. Function composition defines a variable in terms of another one while reducing the level of dependencies; and an inverse function comes into play when checking a correlation between dependent and independent variables. This paper will outline and solve a true composition and inverse function. The functions are: fx=2x+5 gx=x2-3 hx=7-x3
Examples 2.4 (pages 55-56), 2.6 (page 57), 2.10 (page 67) - Descriptive Statistics The first task in analyzing a data set is to describe it. In addition to the graphical methods covered in examples 2.1 and 2.2, this usually involves computing the numerical measures of central tendency (i.e the mean and or median), and numerical measures of the variability of the data (i.e., the standard deviation and the variance). This tutorial will demonstrate how to use Minitab to compute the descriptive statistic(s) for a dataset for text examples 2.4, 2.6, and 2.10. After loading the dataset R&D.MTW into Minitab begin by: 1. Clicking on Stat.
Many other terms carry a similar or slightly different meaning to data mining, such as knowledge mining from data, knowledge extraction, data/pattern analysis, data archaeology, and data dredging. Many people treat data mining as a synonymfor another popularly used term, Knowledge Discovery fromData, or KDD. Alternatively, others view data mining as simply an essential step in the process of knowledge discovery. Knowledge discovery as a process is depicted in Figure 1.4 and consists of an iterative sequence of the following steps: 1. Data cleaning (to remove noise and inconsistent data) 2.
