Contact Us Array Formulas and Functions The worksheet formulas that we described in Excel Spreadsheets return a single value that is assigned to the cell that contains the formula. Excel also allows you to define a formula that assigns values to a range of cells at the same time. These are called array formulas and they will be used quite often throughout this website. Array formulas We now show how to create formulas that modify multiple cells at the same time.

High School Statutory Authority: Algebra I, Adopted One Credit. Students shall be awarded one credit for successful completion of this course.

This course is recommended for students in Grade 8 or 9. Mathematics, Grade 8 or its equivalent. By embedding statistics, probability, and finance, while focusing on fluency and solid understanding, Texas will lead the way in mathematics education and prepare all Texas students for the challenges they will face in the 21st century.

The placement of the process standards at the beginning of the knowledge and skills listed for each grade and course is intentional. The process standards weave the other knowledge and skills together so that students may be successful problem solvers and use mathematics efficiently and effectively in daily life.

The process standards are integrated at every grade level and course. When possible, students will apply mathematics to problems arising in everyday life, society, and the workplace. Students will use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution.

Students will select appropriate tools such as real objects, manipulatives, paper and pencil, and technology and techniques such as mental math, estimation, and number sense to solve problems.

Students will effectively communicate mathematical ideas, reasoning, and their implications using multiple representations such as symbols, diagrams, graphs, and language.

Students will use mathematical relationships to generate solutions and make connections and predictions. Students will analyze mathematical relationships to connect and communicate mathematical ideas. Students will display, explain, or justify mathematical ideas and arguments using precise mathematical language in written or oral communication.

Students will study linear, quadratic, and exponential functions and their related transformations, equations, and associated solutions.

Students will connect functions and their associated solutions in both mathematical and real-world situations. Students will use technology to collect and explore data and analyze statistical relationships.

In addition, students will study polynomials of degree one and two, radical expressions, sequences, and laws of exponents. Students will generate and solve linear systems with two equations and two variables and will create new functions through transformations. The student uses mathematical processes to acquire and demonstrate mathematical understanding.

The student is expected to: The student applies the mathematical process standards when using properties of linear functions to write and represent in multiple ways, with and without technology, linear equations, inequalities, and systems of equations.

The student applies the mathematical process standards when using graphs of linear functions, key features, and related transformations to represent in multiple ways and solve, with and without technology, equations, inequalities, and systems of equations.

The student applies the mathematical process standards to formulate statistical relationships and evaluate their reasonableness based on real-world data. The student applies the mathematical process standards to solve, with and without technology, linear equations and evaluate the reasonableness of their solutions.

The student applies the mathematical process standards when using graphs of quadratic functions and their related transformations to represent in multiple ways and determine, with and without technology, the solutions to equations.

The student applies the mathematical process standards to solve, with and without technology, quadratic equations and evaluate the reasonableness of their solutions.

No. & Date Asked Question # 12/24/ Suppose a sample of farmers is to be selected for estimating the cost of cultivation of maize per hectare. Statistics Calculator will compare two percentages to determine whether there is a statistically significant difference between them. It will also calculate confidence intervals around a percent. Statistics For Dummies, 2nd Edition () was previously published as Statistics For Dummies, 2nd Edition (). While this version features a new Dummies cover and design, the content is the same as the prior release and should not be considered a new or updated product.

The student formulates statistical relationships and evaluates their reasonableness based on real-world data. The student applies the mathematical process standards when using properties of exponential functions and their related transformations to write, graph, and represent in multiple ways exponential equations and evaluate, with and without technology, the reasonableness of their solutions.

The student applies the mathematical process standards and algebraic methods to rewrite in equivalent forms and perform operations on polynomial expressions. The student applies the mathematical process standards and algebraic methods to rewrite algebraic expressions into equivalent forms.

The student applies the mathematical process standards and algebraic methods to write, solve, analyze, and evaluate equations, relations, and functions. Students shall be awarded one-half to one credit for successful completion of this course.Statistics Principles of Statistics has been evaluated and recommended for up to 4 semester hours and may be transferred to over 2, Resampling Statistics.

Rationale Much of modern statistics is anchored in the use of statistics and hypothesis tests that only have desirable and well-known properties when computed from populations that are normally distributed.

While it is claimed that many such statistics and hypothesis tests are generally robust with respect to non . A normal distribution is more commonly known as a bell curve. This type of curve shows up throughout statistics and the real world. For example, after I give a test in any of my classes, one thing that I like to do is to make a graph of all the scores.

I typically write down 10 point ranges such. How to perform the Shapiro-Wilk test for samples with up to 5, elements using Excel formulas. Statistics Calculator will compare two percentages to determine whether there is a statistically significant difference between them. It will also calculate confidence intervals around a percent.
