The sum of 5,238 and 2,794 is 8,032.
What is addition?In math, addition is the process of adding two or more numbers together. Addends are the numbers that are added, while the sum refers to the result of the operation.
Given: 5,238 + 2,794
To add the estimate, we place the given 4-digit number 2794 below the given 4-digit number 5238, and then group the numbers into columns according to their places, such as once, tens, hundreds, and thousands.
The numbers are now added column-by-column. First, we add the number in the one's column (8+4=12), then in the tens column after carrying 1 (9+3+1=13), in the hundreds column carrying 1(2+7+1=10) and in the thousands column carrying 1 again (5+2+1=8).
So the final result of the addition is 8,032.

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.

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

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.

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.

Determine whether each sequence is geometric. If so, identify the common ratio and find the next two terms. 1,3,5,7, . . . .
The sequence is in an arithmetic sequence, common difference is 2, next two term is 9 and 11.
The arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
Here the sequence is 1, 3, 5, 7....
Here the sequence is in arithmetic sequence, so the common difference(d) is 3-1 = 5-3 = 2
So the common difference is 2
Now we need to find the next two terms, and for this, we have the formula to find the nth term of the sequence,
[tex]a_{n}[/tex] = a + (n-1)d
We have to find the 5th and 6th terms.
[tex]a_{5}[/tex] = 1 + 4×2

An executive invest $21,000, some at 8% and the rest at 5% annual interest. if he receives an annual return of $1,470, how much is invested at each rate
Using algebraic expression and equation, an executive assistant invested $14,000 and $7,000 at the rate of 8% and 5% annual interest, respectively.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that an executive invest a total of $21,000, we can express this as:
x + y = 21,000 ⇒ x = 21,000 - y (equation 1)
where x = amount invested at 8% annual interest
y = amount invested at 5% annual interest
If the annual return is $1,470, then the sum of the product of the rate and the amount is equal to the annual return.
8%x + 5%y = $1,470
0.08x + 0.05y = 1,470 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
0.08(21,000 - y) + 0.05y = 1,470
1680 - 0.08y + 0.05y = 1470
-0.03y = -210
y = 7000
amount invested at 5% annual interest = $7000
x = 21,000 - y
x = 21,000 - 7000
x = 14,000
amount invested at 8% annual interest = $14000

W is equal to -22
W=22
Answer:
-22
Step-by-step explanation:
First, lets flip the equation so That we can find W
-8 - 14 = W
The rules of math state that a negative minus a positive can be equal to that negative turned positive plus that positive, the answer turned negative
For example
8+14 = 22
-8-14 =-22
So this means W is -22

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
