I'll do it with a fraction, so let's say 15/45. 15 of the cards are baseball cards, 30 of them are other cards. I would say 15/45, because 45 is the total amount of the cards he has. Only 15 are BASEBALL cards, so it would make sense to say he has a 15/45 chance to pull a baseball card.

Identify the independent and dependent variables. The equation A=25w gives the area A (in square feet) of a rectangular dance fl
kozerog [31]

Answer:

The dependent variable is A

The independent variable is w

Step-by-step explanation:

Given

A = 25w

Required

Identify the variables

In A = 25w

The value of w is independent of the value of A.

In other words:

A derive its own value from w; by multiplying 25 and w.

Take for instance:

w = 3

The value of A would be:

A = 25 * 3

A = 75

Hence:

The dependent variable is A

The independent variable is w

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!
Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>
  • For Example : Let x and y be two monomials which is linear
  • If we product the two linear monomials we get
  • x\times x=x^2 which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let x^2 be the Quadratic monomial has one term with degree 2 and x^2+2x+3 be the quadratic trinomial ( has 3 terms with degree) </h3>
  • If we product the quadratic monomial and quadratic trinomial we have
  • x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)
  • =x^4+2x^3+3x^2
  • Therefore x^2(x^2+2x+3)=x^4+2x^3+3x^2 which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and x^2+5 be the linear binomial has two terms with degree 1</h3>
  • If we product the linear monomial and quadratic binomial we get
  • x\times (x+5)=x(x)+x(5)
  • =x^2+5x
  • Therefore x\times (x+5)=x^2+5x which is a quadratic binomial with degree 2

What is the range of f(x) = -x2 4, if the domain is {2,0,1}?
MrMuchimi
Range is {-(2)^2 + 4, -(0)^2 + 4, -(1)^2 + 4} = {-4 + 4, 0 + 4, -1 + 4} = {0, 4, 3}
