Answer:

Following are the solution to this question:

Step-by-step explanation:

In point a, two pairs value is= \frac{25}{108}

In point b, the three of a kind= \frac{25}{162}

In point c, the value of the full house (three of a kind and a pair) = \frac{25}{648}

In point d, the value of the four of a kind = \frac{25}{1296}

Which statement describes the graph of y + 2 ≥ –4(x – 3)2? a parabola opening up, with shading above the vertex a parabola openi
olasank [31]

Option C. The statement that describes the graph of the equation y + 2 ≥ –4(x – 3)2 is a a parabola opening down, with shading above the vertex.

<h3>How to describe the shape of the parabola.</h3>

To do this you have to create a graph of the equation as seen in the attachment.

From the attachment we can see that the parabola is shaped downwards while we have the shading to be at the top of the vertex.

Determine whether each equation below is linear or nonlinear.
Kruka [31]

Answer:

A) y=\frac{1}{2}x+3 - Linear

B) y=4x+2 - Linear      

C) xy=12 - Nonlinear

Step-by-step explanation:

To determine whether a function is linear or nonlinear.

The function of a straight line is given as :

y=mx+b

where m represents slope of line and b represents the y-intercept.

Any function that can be represented as a function of straight line is called a linear function otherwise it is nonlinear.

We will check the equations given for linear or nonlinear.

A) y=\frac{1}{2}x+3

The function is in the form y=mx+b and hence it is a linear function with slope m=\frac{1}{2} and y-intercept b=3.

B) y=4x+2

The function is in the form y=mx+b and hence it is a linear function with slope m=4 and y-intercept b=2.

C) xy=12

On solving for y

Dividing both sides by  x

\frac{xy}{x}=\frac{12}{x}

y=\frac{12}{x}

This function cannot be represented in the form y=mx+b, hence it is a nonlinear function.
