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.

He is known for his ability to create shots for himself and is a standout three-point shooter, sharing the single-game NBA record for three pointers made with twelve. Bryant is often cited as one of the highest scorers in the NBA. Though his 45.5 percent career field goal average is considered moderate, on the floor, some of Bryant's best moves are his turnaround jump shot, and his ability to post up his defenders and score with a fade away jump
The first class in a relative frequency table is 50–59 and the corresponding relative frequency is 0.2. What does the 0.2 value indicate? Answer: ____Convert 0.2 to a % by times by 100. So 0.2 = 20%, so 20% of the data is between 50 and 59______________ 3. When you add the values 3, 5, 8, 12, and 20 and then divide by the number of values, the result is 9.6.

Solutions may have infinitely many solutions, one solution, or no solution. Identify four-steps to solving a linear system in three variables The best way to solve a linear equation with three variables is by using the elimination method. To fully explain how to solve this type of linear system it would be nine steps. But here it is broken down into four steps. Choose which variable you want to eliminate; the coefficients of the variables must be exact opposites.
Department Product 1 Product 2 Product 3 Hours Available per week A 2 3.5 3 1200 B 3 2.5 2 1150 C 4 3 2 1400 (29 marks) Answer: Suppose we produce x units of Product 1, y units of Product 2, and z units of Product 3. Then, we expect that 2x + 3.5y + 3z = 1200, 3x + 2.5y + 2z = 1150, and 4x + 3y + 2z = 1400. We then need to solve this system. 3 marks i. Convert the given system to the matrix form: [pic][pic] = [pic] 2 marks ii.
Multiplication: add the exponents. EX: 3. Division: subtract the exponents. EX: Graphical Analysis Why do we do G/A? To determine the equation.
What value is stored in uninitialized variables? * Some languages assign a default value as 0 to uninitialized variables. Algorithm Workbench Review Questions: 3-10 3. Write assignment statements that perform the following operations with the variables a, b, and c. * Adds 2 to a and stores the result in b * Set b= 2 +a * Multiplies b times 4 and stores the result in a * set a= b*4 * Divides a by 3.14 and stores the result in b * set b= 3.14/b * Subtracts 8 from b and stored the result in a * set a= b-8 4. Assume the variables result, w, x, y, and z are all integers, and that w = 5, x = 4, y = 8, and z = 2.
