In this problem, students are given a picture of two triangles that appear to be similar, but whose similarity cannot be proven without further information.
Texas Instruments Activity using TI-83 or 84 series calculator showing domain and range of transformations.
Students examine two different proof techniques via a familiar theorem. Students complete proofs involving properties of an isosceles triangle.
Worksheet on basic polynomial operations.
In this Khan Academy activity, students will be given two sets and describe events as subsets of the outcomes in a sample space using characteristics of the outcomes or as unions, intersections and complements of other events.
In this task, output is given from a computer-generated simulation, generating size-100 samples of data from an assumed school population of 2000 students under hypotheses about the true distribution of yes/no voters.
The purpose of this task is to assess a student's ability to explain the meaning of independence in a simple context.
Texas Instruments activity where Students graph a quadratic function that models the shape of a bridge trestle and then solve the related quadratic equation by completing the square.
Students will use quadratic models to optimize the area of a field for a given perimeter. This is the Desmos treatment of a task that's as old as fields themselves. We emphasize estimation, construction, and formulation, in addition to the graphing and solution you find in traditional treatments.
This task is for instructional purposes only and builds on ''Building an explicit quadratic function.''
This task can be used as an instructional task to develop students' understanding of independence and students' ability to calculate the probability of intersection events using the multiplication rule for independent events.
Builds on students' previous work with conditional probabilities to define independent events. In previous lessons, conditional probabilities were used to investigate whether or not there is a connection between two events. This lesson formalizes this idea and introduces the concept of independence.
This Khan video solves a conditional probability example with probabilities like P(A|B) where the events are about lunch and breakfast.
Students calculate probabilities given a two-way table of data, construct a hypothetical 1000 two-way table given probability information and interpret probabilities in context.
This task lets students explore the concept of independence of events.
Students have the opportunity to collect and explore real data using a box of animal crackers.
The purpose of the task is to connect properties of fractional exponents with ordering of real numbers. One can place the numbers on the number line to emphasize this.
Worksheet that answers the question: How do we choose an appropriate method for solving quadratic equations?
Find remainders, by using long division and the Remainder Theorem, to help decipher a message.
In this Khan Academy activity, students will determine whether a number is real or complex.
