The statement that is not an indication of potential multicollinearity problems is "A sign on a regression slope coefficient is negative when the sign on the correlation coefficient was positive"
The multicollinearity is defined as the theory that several independent variables in the given model is correlated. The variables that does not affected by any other variable is called independent variable
But here the independent variables will be correlated. in option b when the sign on the correlation coefficient was positive a sign on a regression slope coefficient is negative. So the independent variables in the given statements are not correlated
In other options the independent variables are correlated

From a hot-air balloon, Justin measures a 34° angle of depression to a landmark
that's 1424 feet away, measuring horizontally. What's the balloon's vertical distance
above the ground? Round your answer to the nearest hundredth of a foot if necessary.
Answer:
960.50 feet
Step-by-step explanation:
You want to know the height of a balloon if it is 1424 feet horizontally from a landmark at an angle of depression of 34°.
TangentThe geometry of the problem can be modeled as a right triangle with a base angle of 34°, the adjacent leg 1424 feet, and the opposite leg being the height of the balloon. The tangent relation tells us ...
Tan = Opposite/Adjacent
Opposite = Adjacent·Tan
height = (1424 feet)·tan(34°) ≈ 960.50 feet
The balloon's vertical distance from the ground is 960.50 feet.
__
Additional comment
If the angle is measured to the nearest degree, then the height of the balloon is somewhere between 943 feet and 979 feet. The only purpose served by reporting the distance to the nearest 0.01 foot is to see if you can use your calculator correctly.
To make that precision for the height meaningful, the angle would need to be measured with an error less than 0.00014°, about 1/2 arc-second. This is better resolution than the best surveying instruments offer, by a factor of about 30.

Given f(x) = 6x − 8 and g(x) = −5x + 2, what is (f − g)(x)?
The expression which represents the composite function (f - g) (x) as required in the task content is; 11x - 10.
Which expression represents the composite function; (f - g) (x)?It follows from the task content that the expression which represents the composite function (f - g) (x) as required in the task content be determined.
Since the given functions are;
f(x) = 6x − 8 and g(x) = −5x + 2
The composite function; (f - g) (g) is equivalent to;
f (x) - g (x)
Therefore, we have;
(f - g) (x) = 6x - 8 - (-5x + 2)
(f - g) (x) = 6x + 5x - 8 -2
(f - g) (x) = 11x - 10.
On this note, the required expression which represents (f - g) (x) is; 11x - 10.

Evian:_ Toby:_ Jillian:_ b. Which student is running at the fastest rate? Expl c. Jillian is trying out for the cross country team. To make the team, she must run in less than . Will Jillian make the team? Explain.
The time for each of them to cover 1 mile is; Evian = 10 min, Toby = 9 min and Jillian = 12 min. The fastest is Toby and No, Jillian can't make the team.
What is unit rate?A unit rate means a rate for one of something.
Given that, Students at Polk Middle School are given a fitness test.
The fitness test result is;
Evian can run [tex]1\frac{1}{2}[/tex] miles in 15 minutes, Toby can run 2/3 miles in 6 minutes and Jillian can run 3/4 miles in 9 minutes
a) The rate of running in 1 mile = (total miles covered)/(total time taken)
Evian =
3/2 miles in 15 minutes
1 mile = 15x2/3
1 mile = 10 minutes
Toby =
2/3 mile in 6 minutes
1 mile = 6x3/2
1 mile = 9 minutes
Jillian =
3/4 miles in 9 minutes
1 mile = 9x4/3
1 mile = 12 minutes.
b) Since, Toby is covering 1 mile in the least minutes in comparison with other two, therefore Toby is fastest among them.
c) Jillian's rate = 1 mile in 12 minutes
Speed = 1/9 miles per minute
Therefore, she will cover 7/2 miles in = 12x7/2 = 42 minutes
That means, she can't make the team.
Hence, the answers are a) Evian = 10 min, b) Toby = 9 min and Jillian = 12 min, the fastest one is Toby and Jillian can't make the team.

The value of x and y at which function P = 3x+2y becomes maximum are

What is the graph?
Graph is the pictorial representation of given data.
Graph is defined as to create a diagram that shows a relationship between two or more things. An example of graph is to create a series of bars on graphing paper.
The four most common are
1. Probably line graphs,
2. Bar graphs and histograms,
3. Pie charts, and
4. Cartesian graphs
To find the maximum, input the vertices (0,8), (5,4) and (9,0) into the objective function (P = 3x + 2y) to determine which vertex obtains the maximum value.
Note: (5,4) is not a vertex.
(0,8) :
P = 3*0 + 2*8
= 16
(5,4):
P = 3*5 + 2*4
= 23
(9,0):
P = 3*9 + 2*0
= 27.
So, the maximum value = 27 at (9,0).

There are 12 different positive two digit integers can be formed using these digits if a digit can be repeated in an integer.
Integer:
An integer is zero (0), a positive integer (1, 2, 3, etc.), or a negative integer with a minus sign (-1, -2, -3, etc.). A negative number is the additive reciprocal of the corresponding positive number. In mathematics languages, sets of integers are often denoted by a bold Z or a bold {Z}.

P(4, 2) = 4P2
We know that:
[tex]^nP_r[/tex] = n! / (n - r)!
⁴P₂ = 4! / (4 - 2)!

B: y=8x^2−64x−264
C: y=−8x^2+64x+264
D: y=−8x^2−64x+264
The quadratic equation with the given x-intercepts and that passes through the point (1, 192) is the one in option D.
y = -8x^2 -64x + 264
What is the quadratic equation?If a quadratic equation has x-intercepts x₁ and x₂ and a leading coefficient a, we can write the quadratic equation as:
y = a*(x - x₁)*(x - x₂)
Here we know that the x-intercepts are -11 and 3, replacing that in the equation above we will get:
y = a*(x + 11)*(x - 3)
We also know that the line passes through the point (1, 192), replacing the values in the quadratic equation we will get:
192 = a*(1 + 11)*(1 - 3)
192 = a*12*-2
192 = -24*a
192/-24 = a
-8 = a
So the quadratic equation is:
y = -8*(x + 11)*(x - 3)
Expanding this, we will get:
y = -8x^2 -64x + 264

The radius of the 196.25 cm³ cylinder is 2.5 centimeters
What is a cylinder?A cylinder is a solid that has three dimensions, consisting of two circular, parallel bases that enclose a curved pipe like surface in between.
The volume of one cylinder = 2009.6 cubic centimeters
The volume of the other cylinder = 196.25 cubic centimeters
The height of each cylinder, h = 10 centimeters
The formula for finding the volume of a cylinder is; V = π·r²·h

Indigo goes out to lunch.
The bill, before tax and tip, was $10.85.
A sales tax of 3% was added on.
Indigo tipped 18% on the amount after the sales tax was added.
The amount after adding sales tax is,
$10.85 x 3% = 0.3255
⇒ $10.85 + 0.3255 = $11.1755
Now to find the amount after tipped 18% on the amount after the sales tax was added.
$11.1755 x 18% = 2.01159
⇒ $11.1755 + 2.01159 = $13.18709

\sqrt{((-4 - 4)^2 + ((-1) - (-1))^2)} = \sqrt{0 + 0} = 0$
The distance between points X and Z is:
$d(X,Z) = \sqrt{((1 - 4)^2 + (3 - (-1))^2)} = \sqrt{9 + 16} = \sqrt{25}$
We can then find the perimeter of the triangle by adding up the lengths of the sides. In this case, the perimeter is $d(X,Y) + d(Y,Z) + d(X,Z) = \sqrt{41} + 0 + \sqrt{25} = \sqrt{41} + \sqrt{25} = 6.40\ldots$.
Rounded to two decimal places, the perimeter is approximately 6.40.
