Answer: 0.05699
Step-by-step explanation:
The total number of cards in a deck = 52
The total number of black cards = 26
Then ,
The total number of face cards = 12
Then , 
The number of cards that are black and face cards = 6
Then , 
Then , the probability that a randomly drawn hand of four cards contains all black cards or all face cards is given by :-
Answer:
C. square
Step-by-step explanation:
<u>Congruent</u> means "the same" (having the same shape and size).
Any four-sided, 2-dimensional shape with straight sides is called a <u>quadrilateral</u>.
There are 6 special types of quadrilaterals:
<u>Rectangle</u>
- Opposite sides are parallel and equal in length
- All interior angles are 90°
<u>Square</u>
- All sides are equal in length
- All interior angles are 90°
<u>Rhombus</u>
- All sides are equal in length
- Opposite sides are parallel
- Opposite angles are equal
<u>Parallelogram</u>
- Opposite sides parallel and equal in length
- Opposite angles are equal
<u>Trapezoid</u>
- One pair of opposite parallel sides
<u>Isosceles Trapezoid</u>
- One pair of opposite parallel sides
- One pair of non-parallel sides equal in length
- Two pairs of equal base angles
<u>Kite</u>
- Two pairs of adjacent sides equal in length
- The angles included between the sides of differing lengths are equal
<u>Conclusion</u>
A four-sided shape that has four congruent angles and sides is a SQUARE.
Answer:
A. True
explanation:
Inequalities that use ≤ or ≥ symbols are plotted with a solid line.
Answer:
Lets name the first set A and the second one B.
<u>The union:</u>
- A∪B = {-7,0}∪{-3,5} = {-7, -3, 0, 5}
<u>The intersection:</u>
- A∩B = {-7,0}∩{-3,5} = ∅ as no common elements
