What is categorical data?
Ex: Hair color data: {blonde, black, red, blonde, blonde, black, brown, red}
The number represented by a closed dot is a part of the solution set.
Non-real solutions: a parabola that does not intercept the x-axis is said to have complex solutions.
Data that are based on “qualities” such as color, taste, or texture rather than qualities.
When one event causes another to happen.
What is causation?
Ex. Hours of work in income: a change in hours worked causes a change in income.
When one event causes another to happen.
Data that are based on “qualities” such as color, taste, or texture rather than qualities.
When a function is multiplied by a coefficient greater than zero but less than 1.
Property that states that integers are closed under addition, subtraction and multiplication, because the sum, difference
What is a center?
Ex. In a data set {1, 2, 2, 2, 2, 3, 4, 5, 5, 9}. The center can be the median {2.5} or the mode {2}.
Contains at least two inequalities that are joined by either “and” or “or”.
Value at the center or middle of a data set that can be the mean, median, or mode.
A number used to multiply a variable.
A technique used to solve quadratic equations where a quadratic equation is written as the sum or difference of a perfect square and a constant.
Define what a closed dot in a graph means.
Ex. <---
Value at the center or middle of a data set that can be the mean, median, or mode.
The number represented by a closed dot is a part of the solution set.
A set of numbers is said to be closed for a specific mathematical operation when the result obtained after performing the operation on two elements of the same set.
A technique used to solve quadratic equations where a quadratic equation is written as the sum or difference of a perfect square and a constant.
What is closure property?
Ex. {natural numbers} if you add or multiply a natural number with another natural number, you get a natural number {for example, 2 + 3 = 5 or 3 x 4 = 12}, so it is closed; but if you subtract or divide natural numbers you do not always get another natural number {for example: 1 - 2 = -1: or 1 / 2 = 0.5} which is not closed.
A set of numbers is said to be closed for a specific mathematical operation when the result obtained after performing the operation on two elements of the same set.
A technique used to solve quadratic equations where a quadratic equation is written as the sum or difference of a perfect square and a constant.
Contains at least two inequalities that are joined by either “and” or “or”.
When a function is multiplied by a coefficient greater than zero but less than 1.
Define Closure property for integers.
Ex. -2 + 6 = 4; 6 - 7 = -1: 3 / 5 = 0.60 {and 0.60 is not an integer}
When one event causes another to happen.
A number used to multiply a variable.
Non-real solutions: a parabola that does not intercept the x-axis is said to have complex solutions.
Property that states that integers are closed under addition, subtraction and multiplication, because the sum, difference or product of two integers is.
What is a coefficient?
Ex. x^2 + 8x + 16, where 8 is the coefficient of x in the term 8x.
A number used to multiply a variable.
Property that states that integers are closed under addition, subtraction and multiplication, because the sum, difference or product of two integers is.
Contains at least two inequalities that are joined by either “and” or “or”.
Data that are based on “qualities” such as color, taste, or texture rather than qualities.
What does "complete the square" mean?
Ex.
x^2 + 6x + 16 = 0
x^2 + 6x = -16 .
x^2 + 6x + 9 = -16 + 9
(x + 3)^2 = -7
(x + 3)^2 + 7 = 0
Non-real solutions: a parabola that does not intercept the x-axis is said to have complex solutions.
A set of numbers is said to be closed for a specific mathematical operation when the result obtained after performing the operation on two elements of the same set.
When a function is multiplied by a coefficient greater than zero but less than 1.
A technique used to solve quadratic equations where a quadratic equation is written as the sum or difference of a perfect square and a constant.
What are complex solutions?
Ex. For x^2 = -9, no real number can be squared to get -9.
Value at the center or middle of a data set that can be the mean, median, or mode.
Data that are based on “qualities” such as color, taste, or texture rather than qualities.
Non-real solutions: a parabola that does not intercept the x-axis is said to have complex solutions.
The number represented by a closed dot is a part of the solution set.
What is a compound inequality?
Ex.
2 < 3 + x < 10
-1 < x < 7
Contains at least two inequalities that are joined by either “and” or “or”.
Hours of work in income: a change in hours worked causes a change in income.
When a function is multiplied by a coefficient greater than zero but less than 1.
A number used to multiply a variable.
What does "compressing a function" mean?
Value at the center or middle of a data set that can be the mean, median, or mode.
When a function is multiplied by a coefficient greater than zero but less than 1.
A set of numbers is said to be closed for a specific mathematical operation when the result obtained after performing the operation on two elements of the same set.
The number represented by a closed dot is a part of the solution set.
