Parallelograms are shapes with equal and parallel opposite sides
The most descriptive name for the quadrilateral is rhombus
<h3>How to name the quadrilateral</h3>
The endpoints of the diagonals are given as:
- Endpoints 1: (4,6) and (-3,-1)
- Endpoints 2: (-2,5) and (3,0)
Next, we plot the endpoints on a coordinate plane (see attachment)
From the attached figure, we can see that the quadrilateral is a rhombus
Hence, the most descriptive name for the quadrilateral is rhombus

Step-by-step explanation:
<h3><u>Initial</u><u> </u><u>reading</u><u>:</u></h3>In the box, there are:
- 6 Black pens
- 4 blue pens
- 7 red pens
Total number of pens in the box = 6 + 4 + 7
<u>= 17</u>
<em>If we count pens as outcomes the total number of possible outcomes are 17</em>.

<h3><u>New</u><u> </u><u>reading</u><u>:</u></h3>Clarissa takes out a black pen from the box.
That reduces the number of black pens by 1 which increases the total number of pens by 1 as well.
So now:
- Number of black pens = 6 - 1 =<u> 5 </u>
- Total number of pens = 17 - 1 =<u> </u><u>16</u><u> </u>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
<h3><u>Probability</u><u>:</u></h3>If we want her to pick up a black pen, and she ends up picking one. So, we can say that the outcome is in our favor.
That makes it,
- the number of favorable outcomes = number of black pens
= 5
- and total outcomes = Total number of pens
= 16
For showing it as some percent we'll just multiply the fraction by 100
