Step-by-step explanation:
The values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.
What is the matrix?It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.
We have a matrix A shown in the picture:
| 2 3 3 |
A = | 3 1 2 |
| 7 8 9 |
It is required to find the inverses of a matrix.
To find the inverse of a matrix:
Augment with a 3x3 identity matrix
[tex]=\begin{bmatrix}2&3&3&\mid \:&1&0&0\\ 3&1&2&\mid \:&0&1&0\\ 7&8&9&\mid \:&0&0&1\end{bmatrix}[/tex]
Convert the matrix to the identity matrix.
[tex]=\begin{bmatrix}1&0&0&\mid \:&\frac{7}{2}&\frac{3}{2}&-\frac{3}{2}\\ 0&1&0&\mid \:&\frac{13}{2}&\frac{3}{2}&-\frac{5}{2}\\ 0&0&1&\mid \:&-\frac{17}{2}&-\frac{5}{2}&\frac{7}{2}\end{bmatrix}[/tex]
Simply it:
[tex]=\begin{pmatrix}\dfrac{7}{2}&\dfrac{3}{2}&-\dfrac{3}{2}\\ \dfrac{13}{2}&\dfrac{3}{2}&-\dfrac{5}{2}\\ -\dfrac{17}{2}&-\dfrac{5}{2}&\dfrac{7}{2}\end{pmatrix}[/tex]
From the inverse matrix the values of unknows can be find:
a = 7/2
b = 3/2
c = -3/2
d = 13/2
e = 3/2
f = -5/2
g = -17/2
h = -5/2
i = 7/2
Thus, the values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.

The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of −0.11 is calculated. What would this imply about the football team winning at home?
The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning.
A.The scatter plot would closely resemble a straight line with a negative slope. The data has a strong, negative correlation, but causation cannot be determined.
B. The scatter plot would not be represented by a line of best fit with a negative slope. C.There is a weak correlation between the football team playing at home and winning, and a causal relationship exists between the team playing at home and winning.
D. There is no causation and almost no correlation between the football team playing at home and winning.
Answers
Answer:
D
Step-by-step explanation:
Given a correlation coefficient of -.11 the correlation would be extremely weak therefore it would have almost no correlation or causation
Why? Well when the value of the correlation is between -.1 and .1 then the relationship is said to have no correlation
-.11 is very close to -.1 thus meaning it would have pretty much no correlation
Answer:
D. There is no causation and almost no correlation between the football team playing at home and winning.
Step-by-step explanation:
A correlation coefficient can be greather than or equal to -1, and less than or equal to 1.
If you have a negative correlation coefficient it means that the correlation between the two variables is a reverse relationship. When one of the variables increase the other one decrease.
The closes the correlation coefficient is to -1 or 1, the correlation is higher,
As -0,11 is not close to -1 it means that the correlation is almost 0 and it is not a correlation between the two variables.

x = 3 and y = 8
Step-by-step explanation:
The Opposite sides of a parallelogram are equal and parallel. It means,
[tex]\dfrac{y}{2}=4\\\\y=8[/tex]
Also,
5x - 6 = 3x
Taking like terms together,
5x -3x = 6
2x = 6
x = 3
So, the values of x and y are 3 and 8 respectively.

the changes in Mr. Connor’s bank account for five days are $50.25, -$22.50, $50.25, -22.50, and -22.50. What is the mean change in his bank account? show your work
Answers
Answer:
8.6
Step-by-step explanation:
-22.50 x 3 = -67.50
50.25 x 2 = 100.50
100.50 + -67.50 = $43
43 divided by 5

Hope this helps :)
The mean change in Connor's bank account is $6.6.
What is mean?Mean is an average of values of a set. Arithmetic mean, geometric mean and harmonic mean are the type of mean.
Given that,
Changes in Mr. Connor's bank account for five days are $50.25, -$22.50, $50.25, -22.50, and -22.50.
To find mean change in Connor's bank account,
First determine total change in Connor's bank account
Total change = 50.25 -22.50 + 50.25 - 22.50 - 22.50
= 33
Mean change = total change/ number of days
Mean change = 33/5
= 6.6

b) The division property of equality
Step-by-step explanation:
Here, we want to know the correct step to use
From the given question, to proceed;
All we have to do is to move the value that has a negative value on the left hand side to the right hand side
what accompanies this is the addition of the both terms, on the right hand side
After this, we now proceed to divide the sum by the coefficient of x
Thus, the correct choices are;
a) The addition property of equality
b) The division property of equality
Determine if line AB is tangent to the circle. Type
your answer below and EXPLAIN HOW YOU KNOW.
This should be a full sentence using the vocabulary
we have discussed.
Answers
Answer:
If AB is a tangent to the circle, the triangle ABO is right angled, as the angle where a tangent meets the circumference is always 90 degrees.
We also know that Pythogoras' theorem only holds for right angled triangles.
The hypotenuse is 12 + 8 as 12 is the radius so is 20.
16^2+12^2 = 256 + 144 = 400 = 20^2 so AB must be tangent.
A flowerbed has an area of 18 square meters. What is the largest possible perimeter of the flowerbed
Answers
Answer:
38m
Step-by-step explanation:
Area of rectangle = length x breadth
perimeter of a rectangle = 2 x( length + breadth)
The factors of 18 are 1,2, 3,6,9,18
The possible areas and perimeters of the flowerbed based on the factors are
1 x 18 = 18cm^2 Perimeter = 2(1+18) = 38
2 x 9 = 18cm^2 perimeter = 2 (2+9) = 22
3 x 6 = 18cm^2 perimeter = 2 (6 +3) = 18
the greatest is 38m
