I suppose K is the matrix
[tex]K = \begin{bmatrix}14 & -13 & 0 \\ 3 & 8 & -1 \\ -10 & -2 & 5\end{bmatrix}[/tex]
To compute det(K), you can use a simple cofactor expansion along the first row:
[tex]\det(K) = 14\times\det\begin{bmatrix}8 & -1 \\-2 & 5\end{bmatrix} - (-13)\times\det\begin{bmatrix}3 & -1 \\ -10 & 5\end{bmatrix} + 0\times\det\begin{bmatrix}3 & 8 \\ -10 & -2\end{bmatrix} \\\\ \det(K) = 14\times(8\times5-(-1)\times(-2)) + 13\times(3\times5-(-1)\times(-10)) + 0 \\\\ \det(K) = 14\times38 + 13\times5 = \boxed{597}[/tex]

Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more _______________ predicted values will be.
a.
accurate
b.
quadratic
c.
scattered
d.
variable
The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.
What is Regression analysis?
A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.
Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).
Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

The value of a car dropped from $23,600 to $21,900 over the last year. Determine the actual and relative change in this situation.
Actual Change: ? This car's value decreased by $
last year.
Round your answer to the nearest dollar.
Relative Change: ? This car's value decreased by
% last year.
Round your answer to the nearest tenth of a percent.
Answer:
The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.
Step-by-step explanation:
It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].
So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].
So, the actual change in this car's value is $[tex]1700[/tex].
The relative change can be given by the expression,
[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]
Substituting values, the relative change can be given by,
[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]

Hi there!
Given;
f(x) = 5x-1
Now; Simply keep the value of x in the given function.
f(1) = 5*1-11
= -6
Again;
f(3) = 5*3-11
= 15-11
= 4
Therefore, f(1) = -6 and f(3) = 4.

Make up a data set (n = 10) that has the same minimum value, same median, and same maximum value, but a larger IQR than the boxplot shown.
a. Give your 10 numbers.
b. Give the 5-number summary for your data.
c. Describe your strategy for figuring this out.
The 10 hypothetical numbers which meets the conditions given on the question may include :
1, 2, 3, 5, 6, 6, 7, 10, 10, 12
The five number summary include the maximum, minimum, lower quartile, Median and upper quartile of a distribution.
The five number summary of the hypothetical data are:
Median: 6
Minimum: 1
Maximum: 12
Lower quartile: 2.75
Upper quartile: 10
Comparing the 5 - number summary of the hypothetical data with that of the given boxplot.
From the given boxplot shown :
Minimum value = 1
Maximum value = 12
Median = 6
LOWER QUARTILE, Q1 = 4
UPPER QUARTILE, Q3 = 8
IQR = (Q3 - Q1) = 8 - 4 = 4
THE 10 made up numbers :
1, 2, 3, 5, 6, 6, 7, 10, 10, 12
The five number summary for the made up data :
Median = 1/2(n+1)th term = 5.5th term = (6+6)/2 = 6
Minimum: 1
Maximum: 12
First quartile = 1/4(n+1)th = 2.75th term = (2+3)/2 = 2.5
Third quartile: 3/4(n+1)th term = 8.25 = (10+10)/2 = 10
Interquartile Range: (10 - 2.5) = 7.5
The original data values and hypothetical data have the same minimum and maximum and median values. The hypothetical data has an higher IQR value than the original data.Learn more : https://brainly.com/question/12992903?referrer=searchResults

If you like, you can solve this by multiplying both sides of the equation by 7.
(x/7)(7) = 6(7)
x = 42
Answer: The correct answer is: " x = 42 . "
_____________________
Step-by-step explanation:
------------------------------------------
Given:
x/7 = 6 ; Solve for "x" ;
_____________________
"x" divided by "7" equals "6" ;
to solve for "x"
______________________
Multiply Each Side of the equation by "7" :
______________________
→ " 7 * [tex](\frac{x}{7}) = 6 * (7)[/tex] ;
______________________
On the "left-hand side" of the equation; the "7's" cancel out;
→ {since: " 7 / 7 = 1 " } ;
___________________
and on the "right-hand side" of the equestion:
→ 6 * 7 = 42 ;

please show work 3d – 4 + d = 8d – (-12)
Answer:
d = -4
Step-by-step explanation:
3d – 4 + d = 8d – (-12)
3d - 4 + d = 8d + 12
4d - 4 = 8d + 12
(4d - 4d) - 4 = (8d - 4d) + 12
-4 = 4d + 12
-4 - 12 = 4d (+ 12 - 12)
-16 = 4d
-16/4 = 4d/4
d = -4
Answer:
d= -4
Step-by-step explanation:
3d- 4 +d = 8d + 12
4d - 4 = 8d + 12
4d = 8d + 16
-4d = 16
d= -4

The trick to this is looking at the denominator. If the numerators are the same for all fractions you are comparing then things are going to be a bit easier for comparing them. The one that has the biggest denominator is small and the one with the smaller denominator is a bigger fraction.

A. 2
B. 3
C. 5
D. 8
Answer:
The value of m is 3
Step-by-step explanation:
(5^4)m =5^12
M = 3
(5^4)3 =5^4*3=12
(5^4)3 = 5^12
Answer:
(5 ^4)^m = (5)^12
625^m = (5)^12
Taking logs of both sides
log(625) *m = log (5) *12
m = log (5) *12 / log(625)
m = 0.69897000434 * 12 / log (625)
m = 0.69897000434 * 12 / 2.7958800173
m = 0.69897000434 * 12 / 2.7958800173
