Need help understanding this question and what the answer would be.

Answer:
Step-by-step explanation:
A quadrilateral is a parallelogram when opposite sides are parallel. This will be the case when ...
- one pair of opposite sides are parallel and the same length (choice B)
- each pair of opposite sides is the same length (choice E)
An isosceles trapezoid has one pair of parallel sides and the other pair of opposite sides the same length, so that is not sufficient to describe a parallelogram. (Choices A and C describe this condition.)
A line segment is always congruent to itself, so that fact establishes nothing about a parallelogram. (choice D)
_____
<em>Comment on opposite sides equal</em>
Choice E can also describe an hourglass-shaped figure. We assume here that the quadrilateral is convex, with no sides crossing each other.

Answer:
The mean is of 45.
The standard deviation is 2.28.
Step-by-step explanation:
The mean is the sum of all values divided by the number of values.
The standard deviation is the square root of the sum of the difference squared between each value and the mean, and divided by the number of values.
Mean:
The mean is of 45.
Standard deviation:
The standard deviation is 2.28.
Answer:
- Only Drawing D has KL being a symmetrical segment.
- Drawings A, B and C have no axis of symmetry.
- Tylko rysunek D ma KL będący segmentem symetrycznym.
- Rysunki A, B i C nie mają osi symetrii.
Step-by-step explanation:
English Translation
In which drawing was the symmetrical segment of KL drawn? Which of these letters has no axis of symmetry?
Solution
The attached image to the question is presented in the attached image to this Solution.
Symmetry is a concept where a figure/shape has half of its part being a mirror image of the other part.
About the line or axis of symmetry, the structure or figure can be rotated at right angles or whole number multiples of right angles and the resulting structure is still the same as the one we started with.
Of the 4 drawings, only drawing D satisfies this conditions/criteria. And Hence, it is the only drawing amongst the four with an axis of symmetry.
In Polish/Po polsku
Załączony obraz do pytania jest przedstawiony na załączonym obrazku do tego rozwiązania.
Symetria to koncepcja, w której figura / kształt ma połowę swojej części stanowiącą odbicie lustrzane drugiej części.
W odniesieniu do linii lub osi symetrii, strukturę lub figurę można obracać pod kątem prostym lub wielokrotności liczby całkowitej pod kątem prostym, a wynikowa struktura jest nadal taka sama jak ta, od której zaczęliśmy.
Z 4 rysunków tylko rysunek D spełnia te warunki / kryteria. I dlatego jest to jedyny rysunek wśród czterech z osią symetrii.
Hope this Helps!!!
Mam nadzieję że to pomoże!!!
