The residual plot represents a linear model because (a) there is no clear pattern
How to determine the if the residual plot represents a linear model?The given parameters are:
The graph
The table
For a residual plot to represent a linear model, the following must be true
The points on the residual plot must be randomly dispersed on the plot
This means that all residual plots that have random points are linear models
From the attached graph, we can see that the points on the graph are randomly dispersed
Hence, the residual plot represents a linear model because (a) there is no clear pattern

What is the slope of the line that passes through the points (-7, -10) and
(-19, -10)? Write your answer in simplest form.
Answers
To find the slope, we subtract the two y’s then do the same for x. That would look like:
(-10) - (-10) = 0
(-19) - (-7) = -12
Our fraction answer is 0/12. Because the slope has 0 as a numerator, we identify this as a slope of 0. This forms a horizontal line.
Final answer: The slope of the line is 0.
A spaceship has a mass of 9000kg. The spaceship is launched from Earth and lands on a distant planet, where it has a gravity of 25 m/s2. What is the weight?
Answers
The weight of the spaceship that has a mass of 9000kg is 22936kg.
How to illustrate the information?It should be noted that the mass in a body simply means the measure of the quantity if the matter that the body has.
It should be noted that it is also the body of the inertia.
In this case, the spaceship has a mass of 9000kg. The spaceship is launched from Earth and lands on a distant planet, where it has a gravity of 25 m/s². Therefore, the weight will be:
= 9000 /9.81 × 25
= 22936kg
Therefore, the weight of the spaceship that has a mass of 9000kg is 22936kg.

Find the length indicated FIND IK HELP
Answers
Answer:
Here is the answer, let me know if I did it wrong.
Answer:
IK = 13 and x = - 12
Step-by-step explanation:
Let's write down each segment and if available express it in terms of x which has to be determined in order to find length of segment IK
We have IK = x + 25 (to be determined)
JK = 2x + 30 (1)
KL (unknown)
IL = x + 34 (2)
JL = 15 (3)
The entire segment
IL = IJ + JL
Substituting for JL = 15 we get IL = IJ + 15
But we are given IL = x + 34
IJ + 15 = x + 34
IJ = x + 34 -15 = x + 19 (4)
IK = IJ + JK
Substituting for IJ = x + 19 from equation (4) and JK = 2x + 30 from equation (1) we get IJ + IK = x + 19 + 2x + 30 = 3x + 49
But we are given that IK = x + 25
So
3x + 49 = x + 25
Moving x from the RHS to the LHS and 49 from the LHS to the RHS we get
3x-x = 25 - 49
2x = -24
x = -12
IK = -12 + 25 = 13
We can verify this by finding the lengths of each segment and seeing they are consistent
We have
IJ = x + 19 = -12 + 19 = 7
JK = 2x + 30 = 2(-12) + 30 = -24 + 30 = 6
IL = x + 34 = -12 + 34 = -23
We also have the fact that JK + KL = JL = 15
Substituting for JK we get
6 + KL = 15
KL = 15-6=9
Total segment length = 7+6 + 9 = 22
x + 34 = -12 + 34 = 22
So it is consistent
One side of a rectangle is 9 feet shorter than three times another side. Find the length of the shorte
ide if we also know that the perimeter of the rectangle is 126 feet.
F=?
Answers
The shorter side of the rectangle is 18 feet.
How to Find the Perimeter of a Rectangle?Perimeter of a rectangle = 2(l + w), where w is the width of the rectangle and l is its length.
Given the following:
Another side of the rectangle = width = w
One side of the rectangle = length = 3w - 9
Perimeter of the rectangle = 126 feet
Therefore:
2(3w - 9 + w) = 126
2(4w - 9) = 126
8w - 18 = 126
8w = 126 + 18
8w = 144
8w/8 = 144/8
w = 18
One side of the rectangle = 3w - 9 = 3(18) - 9 = 45
Therefore, the shorter side of the rectangle is 18 feet.

Answers
Step-by-step explanation:
x = apples picked from the tree
x1 = x/2 + 2
x2 = (x - x1)/2 + 2 = (x - (x/2 + 2))/2 + 2 =
= (x - x/2 - 2)/2 + 2 = (x/2 - 2)/2 + 2 =
= x/4 - 1 + 2 = x/4 + 1
x3 = (x - x1 - x2)/2 + 2 = (x - (x/2 + 2) - (x/4 + 1))/2 + 2 =
= (x - x/2 - 2 - x/4 - 1)/2 + 2 =
= (x/4 - 3)/2 + 2 = x/8 - 3/2 + 2 = x/8 + 1/2
x - x1 - x2 - x3 = 1
x - x/2 - 2 - x/4 - 1 - x/8 - 1/2 = 1
x/8 - 3 - 1/2 = 1
x/8 = 4 1/2 = 9/2
x = 9×8/2 = 9×4 = 36
she had originally 36 apples
x1 = 20

Does the given matrix, A, have an inverse? If it does, what is A-¹? (1 point)
Answers
The inverse of a matrix A is A^-1. And I, the identity matrix, is equal to A.A^-1.
The square matrix needs to be non-singular and have a non-zero determinant value in order to get the inverse matrix. Let's think about the 2 x 2 square matrix A.
Inverse of matrix:
A^(-1)=Adj A/|A|
A-1 stands for Inverse of Matrix for matrix A. There is a straightforward formula for calculating the inverse of a 2 × 2 matrix. In order to find the inverse of a matrix of order 3 or higher, we also need to be aware of the matrix's determinant and adjoint. When multiplied by the provided matrix, the other matrix that serves as the inverse of that matrix yields the multiplicative identity.
There are two ways to find a matrix's inverse. Through the use of an adjoint of a matrix and simple processes, it is possible to derive the inverse of a matrix. Row or column transformations can be used to carry out the basic operations on a matrix. Additionally, the adjoint and determinant of the matrix can be used to apply the inverse of matrix formula in order to get the inverse of a matrix.

Which point is a reflection of Z (5 1/2, 3) across the x-axis
Answers
The reflection of Z (5 1/2, 3) across the x-axis is (5 1/2, -3).
Here,
The given point is Z (5 1/2, 3).
We have to find the point of reflection of Z (5 1/2, 3) across the x-axis.
What is Reflection across x-axis?
A point after reflection across the x-axis, the x- coordinate remains the same but y - coordinate is taken to be the additive inverse.
Now,
Since, The given point Z (5 1/2, 3) is lie on first coordinate.
Hence, The reflection of the point Z (5 1/2, 3) is lie on the third coordinate.
And, In the third coordinate the x-coordinate is positive and y-coordinate is negative.
Since, The rule of the reflection across x- axis is,
(x, y) → (x, -y)
So, The reflection of the point Z (5 1/2, 3) across the x - axis = (5 1/2, -3)
Therefore, The reflection of Z (5 1/2, 3) across the x-axis is (5 1/2, -3).

The coordinates of the point 3/10 of the way from a to b is (-0.3, -6.3)
How to determine the coordinates of the point?The given parameters are:
the coordinates of b is (9,7) the coordinates of a is (-4,-6)The position of the point is given as:
Location = 3/10
Express as ratio
m ; n = 3 : 10 - 3
This gives
m ; n = 3 : 7
The coordinates of the point are then calculated as:
Point = Location * (mx2 + nx1, my2 + ny1)
This gives
Point = 3/10 * (3 * 9 + 7 * -4, 3 * 7 + 7 * -6)
Evaluate
Point = 3/10 * (-1, -21)

If m angle A=5x +29 then what is the smallest integer value of x for which angle A would be classified as obtuse
Answers
The smallest integer value of x for which angle A would be classified as obtuse is 14°
What is an obtuse angle?An obtuse angle can be defined as an angle that is greater than 90 degrees.
This can be expressed as;
Obtuse angle > x > 90°
Given the angle as A = 5x +29
Let's assume that the value of the obtuse angle is 99 which is greater than 90 degrees.
Now, we have to equate the expression for angle A to 91 degrees.
We have;
5x + 29 = 99
collect like terms
5x = 99 - 29
subtract like terms
5x = 70
To make 'x' the subject, divide both sides by the coefficient of x
5x/5 = 70/5
x = 14°
Thus, the smallest integer value of x for which angle A would be classified as obtuse is 14°
