The three inequalities are y ≤ 18 - x, x + y ≤ 1.50, and x > 4.
What is inequality?Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given that Rashaad has x dimes and y nickels having no less than 18 coins. The total amount is $1.50. The number of dimes is at least 4.
The inequalities formed by the given data are:-
y ≤ 18 - x,
x + y ≤ 1.50,
x > 4.
The graphical representation of the inequalities is shown in the attached graph below with the answer.
Therefore, the three inequalities are y ≤ 18 - x, x + y ≤ 1.50, and x > 4.

Answer:
Asking people at an international airport can be thought of as bias because there might a lot of people at the airport who are old and who like to travel.
Asking people whether they’d prefer Italy or France could be bias because what if the people are Italian? Then they’d obviously choose Italy. Or maybe they’re French and they’ve lived in France and been to France too many times and they’d rather visit Italy.
If 86% of people asked took a French course, you can assume they want to learn French (obviously) and that they probably want to learn French so they can visit and be able to communicate with others in France.

Charlie's phone number is 555-3703. If he places each of the digits in a bowl and randomly selects one number at a time without replacement, what is the probability that lie will choose his phone number?
The probability that he will choose his phone number is 1/420.
we are given the phone number 555- 3703, which contains 7 digits : 3 5s, 2 3s, 1 0s, and 1 7s,
The formula for the probability of an event is:
no.of possible cases / total number of cases.
For the final result, we need to find the individual digits' probabilities and multiply them.
So, the probability of first digits: 3/7
the probability of Second digits: 2/6
the probability of third digits: 1/5
the probability of fourth digits: 2/4
the probability of fifth digits: 1/3
the probability of Sixth digits: 1/2
Therefore the probability of picking up his phone number is
= 3/7 * 2/6 *1/5 * 2/4 * 1/3 *1/2
= 1/420

Answer:
Step-by-step explanation:
Use the distributive property to remove the parentheses. Then use the addition property of equality to move the variables to the left and the constants to the right. Then simplify both sides of equation. Divide -1.76 to both sides of equation to solve for d.
1.8(6.4d + 4) = 1.6(8.3d + 6.7)
11.52d + 7.2 = 13.28d + 10.72
11.52d -13.28d = 10.72 -7.2
-1.76d/-1.76 = 3.52/-1.76
d = -2

What is the equilibrium condition given by ? (that is, what does this derivative equal in equilibrium?)
The second derivative is zero tells us nothing about stability.
What is a solution's equilibrium?
Differential equations can have solutions called equilibrium solutions when the derivative along those solutions equals zero. In other words, at that solution, the slope is a horizontal line.
Consider the following potentials:
U(x) = [tex]x^{4}[/tex]
U(x ) = [tex]x^{6 } - x^{4}[/tex]
U( x ) = [tex]x^{4} + x^{3}[/tex]
All three of these potentials have an equilibrium point at x=0. All three of these potentials are such that the second derivative of U(x) at this equilibrium point is zero.
However, you should convince yourself (perhaps by plotting these potentials) that in the first case the equilibrium is stable, in the second case it is unstable, and in the third case the equilibrium is, as you put it, "stable in one direction but unstable in the other".
The second derivative is zero tells us nothing about stability.

Quadrilateral W X Y Z is a rhombus. If m∠ X Y Z=110° , find m∠ Z W Y .
If quadrilateral WXYZ is a rhombus and ∠XYZ = 110°, then ∠ZWY is equal to 110°.
Rhombus is a quadrilateral that is similar to a parallelogram since its opposite sides are parallel with each other and its opposite angles are equal. All four sides of a rhombus are of equal length and the diagonals bisect each other at 90°.
Rhombus has 4 interior angles whose sum is 360°. The opposite angles of a rhombus are equal to each other while the adjacent angles are supplementary.
∠XYZ is the opposite angle of ∠ZWY and opposite angles of a rhombus are equal to each other.
If the measure of ∠XYZ is 110°,
∠XYZ = ∠ZWY
110° = ∠ZWY

In this problem, you will explore changing dimensions in circles.
e. The scale factor from ®A to ®B is b/a . Write an equation relating the circumference (CA) of ®A to the circumference (CB) of ®B .
The equation relating the circumference (CA) of ®A to the circumference (CB) of ®B is a(CA) - b(CB) = 0.
What is scale factor?A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object.
Now it is given that,
scale factor from ®A to ®B = b/a
⇒Ks = b/a
∵ Ks = A/B
By comparison we get,
A = b
and B = a
Thus, circumference (CA) of ®A = 2πr = 2πb
and, circumference (CB) of ®B = 2πr = 2πa
Dividing both we get,
circumference (CA) of ®A/circumference (CB) of ®B = b/a
by cross multiplication we get,
a * circumference (CA) of ®A = b * circumference (CB) of ®B
or, a * circumference (CA) of ®A - b * circumference (CB) of ®B = 0
or, a(CA) - b(CB) = 0
this is the required equation.
Thus, the equation relating the circumference (CA) of ®A to the circumference (CB) of ®B is a(CA) - b(CB) = 0.

In 2004,8 million Americans over the age of 7 participated in mountain biking, and in 2006,8.5 million participated.
c. If participation continues at the same rate, what will be the participation in 2013 to the nearest 10,000 ?
If participation continues at the same rate, the participation in 2013 will be 5.75million i.e. 5750000 .
Slope(m) for given two points (x₁,y₁) and (x₂,y₂) is calculated using the formula
m=(y₂-y₁)/(x₂-x₁)
In the given question ,we will take year as x coordinate and the participation as y coordinate.
Given " The participation in 2004 was 8milllion" , So
The point becomes (2004,8)
and "the attendance in 2006 was 8.5 million" So
the point becomes (2006,8.5)
Now as we have the two points (2004,8) & (2006,8.5) ,
x₁=2004 , y₁=8 , x₂=2006 , y₂=8.5
slope can be calculated as
m=(8.5-8)/(2004-2006)
m=0.5/2
m=0.25
Hence , the rate of change is 0.25 million participants per year.
It is given in the question that rate of change remains constant.
To predict the attendance for the year 2013.
Let the attendance for the year 2013 be x.
we have (2004,8) and (2013,x)
let m=0.25, x₁=2004 , y₁=8 , x₂=2013 , y₂=x
m=(y₂-y₁)/(x₂-x₁)
Substituting the values above we get
[tex]0.25=\frac{8-y}{2013-2004} \\ \\ 0.25=\frac{8-y}{9}[/tex]
By cross multiplying we get
[tex]0.25*9=8-y\\ \\ 2.25=8-y\\ \\ y=8-2.25[/tex]
[tex]y=5.75[/tex]
Therefore , If participation continues at the same rate, the participation in 2013 will be 5.75million i.e. 5750000.
