what is the distance between the two points in simplest radical form
(−2,−7) and (5,0)
The distance between the two points in simplest radical form(−2,−7) and (5,0) is 9.8995
What is the distance?Distance can be described as the differences that exist between two points and this can be expressed i different form such as the radical form.
We can calculate the distance between the two points by firstly expressed them as :
(−2) - (5) = -7
(-7) - 0 = -7
Then the distance between them can be found as :
Distance = (-7)^2 + (-7)^2 = 49 +49 = 98
Then we will find the square root of the the figure as
= [tex]\sqrt{98}[/tex] = 9.8995
The formula can as well be used to find this by substituting the values of x and y into the formula as :
x1=-2
y1=-7
x2=5
y2=0
[tex]d = \sqrt{ ( x_{2} - x_{1} )^{2} + ( y_{2} - y_{1} )^{2}}[/tex]
then [tex]d = \sqrt{ ( 5 - (-2 )^{2} + ( 0 - (-7) )^{2}}[/tex]
= [tex]\sqrt{ 49^{2} + 49^{2} }[/tex]
= [tex]\sqrt{98}[/tex]

in the presence of changing variability, the estimated standard errors of the ols estimators are inappropriate. what does this imply about using standard testing?
The error term, which refers to the sum of the deviations within the regression line and explains the discrepancy between the theoretical value of the model and the actual observed results, denotes the margin of error inside a statistical model.
What does OLS regression's error term mean?The error term, often referred to as the residual, disturbance, or remaining term, is denoted by the letters e,, or u in various ways in models.Use of an Error Term in a Formula : An error term basically denotes that the model is not entirely precise and yields varying outcomes when used in practical applications. Assume, for instance, that a multiple linear regression function has the following shape:Y=αX+βρ+ϵ
where:
α,β=Constant parameters
X,ρ=Independent variables
ϵ=Error term
During an empirical test, if the actual Y is different from the expected or projected Y in the model, the error term does not equal 0, indicating that other factors affect Y.The OLS estimators will continue to be linear, impartial, and consistent in the presence of autocorrelation. However, because to the absence of a minimal variance, the estimators will no longer be BLUE. It implies that the predictions made using the OLS estimators will be ineffective if the error terms are autocorrelated.To Learn more About error term refer to:

For a particular rectangle, twice the width is 4 meters shorter than the length. The area of the rectangle is 126 square meters. What is the perimeter of the rectangle? ? meters
Let l be the length of the rectangle and w its width.
Then its area is given by:
a = l*w
Its perimeter is given by:
p = 2l + 2w
We also know that, for this specific triangle, we have:
2w = l - 4
l = 2w + 4
a = 126 m²
Applying this result in the area formula, we have:
w*l = 126
w(2w + 4) = 126
2w² +4w = 126
2w + 4w - 126 = 0
Therefore, w = 7 m and l = 2*7 + 4 = 10 m
Then, the perimeter is given by:
p = 2*18 + 2*7 = 36 + 14 = 50 m
A 21-foot beam is to be cut into three pieces so that the second and third piece are each 3 times the length of the first piece. If X represents represents the length of the first piece find the length of each piece.
The length of the first piece is 3 inches, and the second and third pieces are each 9 inches
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Given that a 21-foot beam is to be cut into three pieces so that the second and third pieces are each 3 times the length of the first piece.
We have to determine the length of each piece.
Let x represents the length of the first piece
As per the given condition,
x + 3x + 3x = 21
7x = 21
x = 21 / 7
x = 3
Thus, the first piece is 3 inch
So 2nd piece is 3×3 = 9 inches ( 3 times to first piece )
And 3rd piece is 3×3 = 9 inches ( 3 times to first piece )
Therefore, the length of the first piece is 3 inches, and the second and third pieces are each 9 inches

Given f(x)=2x-5, describe how the graph of g compares with the graph of f.
g(x)=2(0.2x)-5
The graph of g and f have equal intercepts while the slope of the graph of f is 5 times larger than the slope of the graph of g
How to compare the graph of g with the graph of fGiven: f(x) = 2x-5 and g(x)=2(0.2x)-5
To compare the two graphs, we can make use of the equation of a line:
The general form of the equation of a line is y = mx + c
Where m is the slope and c is the intercept
So we will compare two the functions with the equation of a line:
Comparing f(x) = (2x-5) with y = mx + c
The slope(m) of the line = 2 and the intercept(c) = -5
Also, comparing g(x) = 2(0.2x)-5 with y = mx + c
The slope(m) of the line = 2(0.2) = 0.4 and the intercept(c) = -5
Since the slope of f(x) = 2 and the slope of g(x) = 0.4. Thus:
slope of f(x) / slope of g(x) = 2/0.4 = 5
So we can say the slope of f(x) is 5 times the slope of g(x)
Therefore, the graph of g and f have the same intercept. But the slope of f(x) is 5 times the slope of g(x)

A) If the number of nights spent is n, then the function rule here for the total cost is;
T = 25n + 15
B) We are told that the number of nights is 6 nights. Thus, we will just plug in 6 for n into the total cost equation to get;
T(6) = 25(6) + 15
T(6) = $165
C) The cost of 3 nights would be;
T(3) = 25(3) + 15
T(3) = $90

Marques works in a department store selling clothing. He makes a guaranteed salary of $200 per week, but is paid a commision on top of his base salary equal to 10% of his total sales for the week. How much would Marques make in a week in which he made $750 in sales? How much would Marques make in a week if he made x dollars in sales?
The most appropriate choice for percentage will be given by -
Total salary of Marques in a week = $825
If Marques makes $x in sales, his total salary in a week = $([tex]750 + \frac{x}{10}[/tex])
What is Percentage?
Suppose there is a number and that number has to be expressed as a fraction of 100. The fraction is called percentage. For example 2% means [tex]\frac{2}{100}[/tex]
Here,
Guarantee salary of Marques = $200
Sales made by Marques in a week= $750
Percentage commission on total sales = 10 %
Commission received by Marques = [tex]\frac{10}{100} \times 750\\[/tex]
= $75
Total salary of Marques in a week = $(750 + 75)
= $825
If Marques makes $x in sales, his total salary in a week = $([tex]750 + \frac{10}{100}\times x[/tex])
= $([tex]750[/tex] + [tex]\frac{x}{10}[/tex])
