The relation of a right angle vertices interior and exterior is 1:4. Where we can work with other ratio that does not have right

angles, if comparing an exterior angle to an interior angle where a ratio 1:3 is found- how many sides does the polygon have.

Answer:1:3

Answer:

The picture just shows the beginning logic. We now know that we need to find a polygon with an interior angle that has a ratio of 1:3 with its exterior angle.

We can use this formula to find the number of sides of the polygon:

((n-2)×180)/n = 120

(n-2)×180 = 120n

180n - 360 = 120n

60n = 360

n = 6

We now know that the shape has 6 sides with 120 degree interior angles.

A shape with 6 sides is a hexagon.

Answer:  The correct answer is:  

_________________________  

The given "graph" in the bottom right, lowest corner

Step-by-step explanation:

_________________________

Note:  When there is only one (1) equation give for a graph;

          and/or:  only one (1)  "inequality given";  

         we  look for the symbol.

If the symbol is "not" an "equals" symbol (i.e. not an:  =  symbol) ;

 we check for the type of "inequality" symbol.

If there is a:  "less than" (<) ;  or a "greater than" (>) symbol;  the graph of the "inequality" will have "dashed lines" (since there will be a "boundary").

If there is an "inequality" that is a: "less than or equal to" (≤) ;

                                                 or a: "greater than or equal to" (≥) ;

       →   then there will be not be a dashed line when graphed;

          but rather—a "solid line" ;  since "less than or equal to" ;

          or "greater than or equal to" —is similar to:

          "up to AND including"; or: "lesser/fewer than AND including".).

 _________________________  

Note:  We are given the "inequality" :

            →   " y <  x²  + 4x  "  .

_________________________________

Note that we have a "less than" symbol (< ) ; so the graph will have a:

   "solid line" [and not a "dotted line".].

_________________________________

Note that all of the graphs among our 4 answer choices have "dotted lines".

Not that all values (all x and y coordinated) within the "shaded portion" of the corresponding graph are considered part of the graph.  

As such, given any point within the shaded part,  the x and y coordinates must match the inequality (i.e. the given inequality must be true when one puts in the "x-coordinate" and "y-coordinate" into the "given inequality" :

→   " y <  x²  + 4x "  .

_________________________

Likewise, we can take any point within the "white, unshaded" portion of any of the graph, and take the "x-coordinate" and "y-coordinate" of that point, and the inequality: →   " y <  x²  + 4x  "  ;  will not hold true when the "x-coordinate" and "y-coordinate" values of that point— are substituted into the "inequality".  

_________________________

What is the median of this data set? {10, 15, 12, 6, 2}
Vedmedyk [2.9K]

Hello there!

Median is the middle of the data set.

So, first we have to arrange it into proper numerical order (least to greatest).

2,6,10,12,15

Then, we look for the middle number.

It is 10, therefore 10 would be the median of this data set.
