Tables are used to show the relationship between variables in a visual form. The equation of the situation is: [tex]y = 7x[/tex]

The complete table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Given that:

[tex]2\ page = 14\ photos[/tex]

Let:

[tex]y \to pages[/tex]

[tex]x \to photos[/tex]

So, we have:

[tex]2y = 14x[/tex]

Divide by 2

[tex]y = 7x[/tex]

To fill the table, we simply multiply both sides by the same constant.

Multiply by 0.5

[tex]2\ page \times 0.5= 14\ photos \times 0.5[/tex]

[tex]1\ page = 7\ photos[/tex]

Multiply by 2

[tex]2\ page \times 2 = 14\ photos \times 2[/tex]

[tex]4\ page = 28\ photos[/tex]

Multiply by 3

[tex]2\ page \times 3 = 14\ photos \times 3[/tex]

[tex]6\ page = 42\ photos[/tex]

So, the table is as follows:

[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

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).

Answer:

13

Step-by-step explanation:

Since the angles form 180 degrees, it will be what the equation is equal to.

Make the equation:

8r + 5 + 5r + 6 = 180

Combine like terms:

8r + 5 + 5r + 6 = 180

13r + 5 + 6 = 180

13r + 11 = 180

Solve:

13r + 11 = 180

Answer:

-1/2

Step-by-step explanation:

3(y+13 )=36

y+13=12

y=-1

(1/2) x -1 = -1/2

3(y + 13) = 36

Distribute the 3

3y + 39 = 36

Subtract 39 from both sides.

3y = -3

Divide both sides by 3

y = -1

1/2y = 1/2(-1) = -1/2

A calculator can help with these, especially if it is able to deal with rational numbers. (Many graphing calculators and some scientific calculators will do that more or less nicely. My favorite Android calculator app makes arithmetic with fractions and mixed numbers very easy.)

Answer:

7x³ + 7x² + 2x - 8

Step-by-step explanation:

Let the unknown polynomial be a

a + -3x³ + 2x - 5 = 4x³ + 7x² - 3

a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)

a = 4x³ + 7x² - 3 + 3x³ + 2x - 5

a = 7x³ + 7x² + 2x - 8

Answer:

  x = 42

Step-by-step explanation:

You know from your multiplication tables that ...

  42/7 = 6

  x = 42

__

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 ;

___________________

So; we have:  " x = 42 " ; which is our answer.

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
