Answer:

The polygon is a concave polygon

The polygon is irregular polygon

Step-by-step explanation:

Convex polygon is polygon that has all interior angles less than 180°

In a convex polygon, every diagonal of the figure passes only through interior points of the polygon

A line drawn through a convex polygon will intersect the polygon in exactly two points

Some of convex polygons can be regular polygons

Concave polygon is a polygon that has one or more interior angles greater than 180°

In a concave polygon, at least one diagonal of the figure contains points that are exterior to the polygon

A line drawn through a concave polygon, can intersect the polygon in more than two points

Concave polygon never be a regular polygon

From the attached figure

∵ The polygon has one diagonal lies out the interior of the polygon

∴ The polygon is a concave polygon

∵ All the concave polygons are regular polygons

∴ The polygon is irregular polygon

September 6 is a Read Book Day.Polina read 5 times as many pages as Marcus read.Together,the read 108 pages.How many pages did e

Gemiola [76]

Answer:

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Step-by-step explanation:

Let

x -----> number of pages that Polina read

y ----> number of pages that Marcus read

we know that

x+y=108 ----> equation A

x=5y -----> equation B

substitute equation B in equation A and solve for y

$5y+y=108\\6y=108\\y=18$

Find the value of x

$x=5y -----> x=5(18)=90$

therefore

The number of pages that Polina read was 90 and the number of pages that Marcus read was 18

Seven times a number decreased by three-fourths of the same number is 25. What is the number?

Tomtit [17]

Answer:

103/28

Step-by-step explanation:

Let the number be 'x'

Equation:-

7x - 3/4 = 25

7x = 25 + 3/4

7x = 100/4 + 3/4

7x = 103/4

x = 103/(4 x 7)

x = 103/28

Answer:

<h3>"In a linear regression model, the variable that is being predicted or explained is known as <u>_dependent variable</u> It is denoted by y and is often referred to as the response variable".</h3>

Step-by-step explanation:

Given that "In a linear regression model, the variable that is being predicted or explained is known as <u>dependent variable</u> It is denoted by y and is often referred to as the response variable".

Because linear regression models for variables are used to explain or predict the relationship between two variables.
The variable in the given model that is being predicted is called the dependent variable.
