The value of the unknown fourth interior angle of the polygon is 114 degrees.

Hence option B)114° is the correct answer.

A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.

The formula for calculating the sum of interior angles of a polygon is;

S =  ( n − 2 ) × 180°

Where n is the number of sides.

Given that the polygon is the diagram has 4 sides, n = 4

Hence

the sum of interior angles of the polygon is;

S =  ( n − 2 ) × 180°

S =  ( 4 − 2 ) × 180°

S = 2 × 180°

S = 360°

Now, we add the total interior angles in the given polygon and equate to the sum of interior angles of a polygon with 4 sides.

82° + 51° + 113° + x = 360°

246° + x° = 360°

x = 360° - 246°

x = 114°

The value of the unknown fourth interior angle of the polygon is 114 degrees.

Hence option B)114° is the correct answer.

Step-by-step explanation:

First, find the slope using the slope formula,

[tex]m=\frac{5-\left(-2\right)}{-3-\left(-4\right)}[/tex]       solve and simplify, m=7

plug in one pair of coordinates for the y and x for the slope intercept form,

(I'll just use (-3,5))

y=mx+b

5=7(-3)+b

Rewriting the whole as an Equivalent Fraction

Rewrite the whole as a fraction using  9  as the denominator :

        6     6 • 9

   6 =  —  =  —————

        1       9  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :

6.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 -v-59

 ————— • 9 = 0 • 9

   9  

Now, on the left hand side, the  9  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -v-59  = 0

Solving a Single Variable Equation:

6.2      Solve  :    -v-59 = 0

Add  59  to both sides of the equation :

                     -v = 59

Multiply both sides of the equation by (-1) :  v = -59

Answer:

c. there is a positive correlation in-between x and y

Step-by-step explanation:

A regression line is a line that suggests that all the points in a scatter diagram lie on or near one particular line. In a simple regression analysis in which y is the dependent variable and x is the independent variable. If the slope is positive, the bivariate data is also said to have a positive correlation. The positive correlation in-between two variables x and y implies that in general, an increase in x goes hand in hand with an increase in y.

Regression Analysis is defined as the set of statistical and reliable processes for establishing the relationship between the independent and dependent variables.

The correct statement can be given as:

In a simple regression analysis (where y is a dependent and x an independent variable), if the slope is positive, then it must be true that there is a positive correlation between x and y.

The regression line suggests that all the points lie near a particular line. It can be explained as:

1. In a simple regression analysis, the dependent variable is y.

2. Similarly, the independent variable is x.

3. Given, if the slope is positive, then the correlation will be positive.

4. The positive relation implies that if x increases then they will also increase in simple regression analysis.

Thus, in the simple regression analysis there exists a positive correlation between x and y.

Answer:

The percent of increase from 6 to 9 is 50%

Step-by-step explanation:

Percentages

To calculate the percentage increase:

Work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Divide the increase by the original number and multiply the answer by 100.

We are required to find the percent increase from 6 to 9. Here: New number=9, Original number = 6

Increase = 9 - 6 = 3

Divide 3 by 6 and multiply the answer by 100:

3 / 6 * 100 = 50%

The percent of increase from 6 to 9 is 50%

The percent of increase from the number 6 to 9 is 50 percent.

The given numbers are 6 and 9.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The difference of the given numbers

= 9-6

= 3

The percent of increase = 3/6 ×100

= 0.5×100

= 50%

Therefore, the percent of increase from the number 6 to 9 is 50 percent.
