How do I express the difference in the measures of center as a multiple of the measures of variation?
The difference between the measures of center is equal to the measure of variation.
How to illustrate the information?The IQR of the given box plot:
Q1 = 10
Q3 = 18
IQR = Q3 − Q1 = 18 − 10 = 8
Median = 15
Q1 = 4
Q3 = 12
IQR = Q3 − Q1 = 12 − 4 = 8
The difference between the measures of center as a multiple of the measure of variation:
Median of first data set - median of the second data set
IQR = 15 − 7 / 8
= 1
Therefore, the difference between the measures of center is equal to the measure of variation.

As per the question statement, the total cost for cars entering President George Bush Turnpike at Beltline Road is related to the number of cars entering the turnpike at Beltline Road. The costs of different numbers of cars entering the turnpike at Beltline Road are as follows: 1 car, $0.75; 2 cars, $1.50; 3 cars, $2.25; 4 cars, $3.00; 5 cars, $3.75.
Before solving the question we need to know what is domain and range basically.
Ordered pair : {(1,0.750 , (2,1.50) , (3,2.25) , (4,3.00) , (5,3.75)}
Domain is the set which consists of all the first elements of all the ordered pair of the given relation, therefore Domain is {1, 2, 3, 4, 5}.
Range is the set which consists of all the second elements of all the ordered pair of the given relation, therefore Range is {0.75,1.50,2.25,3.00,3.75}
And yes, the given relation is also a function because as the number of cars increases the total cost is also increasing but gradually with a constant value.

Let f(x)=2 x²+8 and g(x)=x-3 . What are f+g and f-g ? What are their domains?
Domain of f + g ( x) = R and f - g ( x) = R
Given :
F(x) = 2x^2 + 8 and g(x) = x-3
From this, we get to know that f(x) and g(x) assume real values for all values of x.
Hence, domain (f)= Real(R) and domain (g)= real ( R ) .
Therefore D (f) and D(g) are Real Number
Now,
A > (f + g ) : R ----> R is given by (f + g) (x)
= f(x) + g(x) = 2x^2 + 8 + x- 3
= 2x^2 + x + 5
Hence, domain ( f + g ) = Real ( R )
B > (f – g) : R---> R is given by ( f-g ) (x)
= f(x) – g(x) = 2x^2 + 8 – ( x – 3)
= 2x^2 -x + 11
Hence, domain ( f - g ) = Real ( R ) .

Write each expression in simplest form. (x⁴/x⁻¹)⁻¹/₅
The simplest form of the expression [tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex] is [tex]\frac{1}{x}[/tex].
The simplest form of a fraction is one with a reasonably prime denominator and numerator. It indicates that, except for 1, there is no common factor between the fraction's numerator (upper portion or top) and denominator (lower part or bottom).
A fraction is a number that has been expressed as a quotient by dividing the numerator by the denominator. Both are integers in a simple fraction. In a complex fraction, a fraction can be found in either the numerator or the denominator.
An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. Two expressions joined by an equal sign form an equation.
Consider the expression,
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex]
Now we know,
[tex]x^{-1}=\frac{1}{x}[/tex]
Therefore,
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{\frac{x^4}{x^{-1}} })^{\frac{1}{5} }[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{x^{-1}}{x^4})^{\frac{1}{5}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{x \times x^4})^{\frac{1}{5}[/tex]
Using the exponential rule,
[tex]n^{b} \times n^{a} = n^{a+b}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = (\frac{1}{x^{5}} )^{\frac{1}{5}[/tex]
[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = \frac{1}{x^{5 \times \frac{1}{5} }}[/tex]

The area of the isosceles triangle is 60 square units
How to determine the valueThe formula for area of an isosceles triangle is expressed as;
Area = bh/2
Where;
b is the base of the triangleh is the height of the triangleNow, let's find the height of the triangle.
Using Pythagorean theorem, we have;
13^2 = 5^2 + h^2
Find the square
169 = 25 + h^2
collect like terms
169- 25 = h^2
h^2 = 144
Find the square root of both sides
h =√ 144
h = 12
Let's find the area
Area = 10 × 12/2
Area = 120/2
Area = 60 square units.

If we want Joe's brother to have more money at the x week, then B(x) has to be greater than J(x)
[tex]B(x) > J(x) \\ 80 + 40x > 170 + 20x \\ 40x - 20x > 170 - 80 \\ 20x > 90 \\ x > \frac{90}{20} \\ x > 4.5 \: \: \: so \: \: \: x = 5[/tex]

For each annual rate of change, find the corresponding growth or decay factor.+ 500%
The corresponding growth factor of +500% is 6
The formula for the annual rate of change is
1 ± r (1)
where r = rate of change
and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.
According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.
Thus, r = + 5
Putting this value in equation (1) we get

The value of K is 2 so that the point A lies on the line given by the equation A (2,1), 3x+ky=8.
Given: Equation is 3x+ky=8
Points A (2,1)
We need to determine the value for K
3x+ky=8 — 1 (Take as equation 1)
Substitute the points in equation 1
So, we take x = 2 and y = 1
3(2) +k (1) = 8
6+k = 8
k = 8 - 6
k = 2
When graphing points on a coordinate plane, it is often helpful to find the value of k that makes the point lie on a line. For this problem, k = 2 so that A (2,1), 3x+ky=8.
