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.
y-y1=m(x-x1) y-5=1/2(x-3) 5. Convert the equations you arrived at in question 2 and question 4 into slope-intercept form. 2: 2(y-4)=(x-1) 2y-8=x-1 2y-x=-1+8 2y=x+7 4: 2(y-5)=(x-3) 2y-10=x-3 2y=x-3+10 2y=x+7 6. Does the point you select matter when your write a point-slope equation? Explain your reasoning using complete sentences.
(TCO 16) What is a “dummy activity?” 7. (TCO 3, 4, & 5) What is the formula for linear regression? Define each part. 8. (TCO 1) What are the four qualitative forecasting approaches that are available to us?
INEQUALITIES 1 BMI Brandon Picone MAT 221: Introduction to Algebra Instructor: Gregory Dlabach Dec 2, 2013 INEQUALITIES 2 BMI and You For this assignment I will be demonstrating how you can find out how to use Inequalities to find whether or not you are overweight. You can use my equations and the examples of my work to find out exactly what category you might fall in. In this equation we are asked to use our own height to find out exactly if I might have a longer life span than the usual person. Before we get started, remember that W=my weight, and H=my height. W=176 and then H=65” In this first compound inequality, I had to take the equivalent inequality and replace it with
c. Incomplete dominance introduces a third phenotype for a gene with two alleles. d. Codominance introduces a third phenotype for a gene with two alleles. e. Epistasis eliminates a progeny class when a gene masks another's expression. f. Incomplete penetrance produces a phenotype that does not reveal the genotype. g. Variable expressivity can make the same genotype appear to different degrees.
Show the mapping or truth table that you used to solve this logic problem. = 22112200 3. Determine the result of 110011002 OR 111111002. Show the mapping or truth table that you used to solve this logic problem. = Lab 1.3 1.
The assignment must include (a) all math work required to answer the problems as well as (b) introduction and conclusion paragraphs. Your introduction should include three to five sentences of general information about the topic at hand. The body must contain a restatement of the problems and all math work, including the steps and formulas used to solve the problems. Your conclusion must comprise a summary of the problems and the reason you selected a particular method to solve them. It would also be appropriate to include a statement as to what you learned and how you will apply the knowledge gained in this exercise to real-world situations.
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.
MAT221: Introduction to Algebra Week 5 Discussion Factoring According to what I calculated, the GCF of 92 and 64 is 4. I found this answer by : Divisor 92 divided by 4 equals 23 and 64 divided by 4 equals 16. I used the factor of numbers to help me. 92/4=23 1,2,4,23,46,92 2/24 2/12 2/6 3/3 64/4=16 1,2,4,8,76,32,64 24=2x2x2x3 Prime factors are also know as natural numbers. It means a number that is more than one and I can only divide it by one, and has no remaining numbers.
