With 4 jacks in the deck of 52, there is a 4/52 = 1/13 probability of drawing 1 jack.
With 13 clubs in the deck, there is a 13/52 = 1/4 probability of drawing 1 card of clubs.
1 of the cards in the deck is both a jack and of suit of clubs, which has a 1/52 probability of being drawn.
P(club OR jack) = P(club) + P(jack) - P(club AND jack) = 13/52 + 4/52 - 1/52 = 16/52 = 4/13
So the answer is B.
Answer:
When the opposite sides of the trapezoid are parallels each other and the sumatory of the inner angles is equal to 180°.
Step-by-step explanation:
The definition of a trapezoid is: a quadrilateral figure that only have two parallels sides and unequal each other. There are diferent types of trapezoids and can be classifiyed according to there inners angles. The rectangulum trapezium has two consecutive angles of 90°. The isosceles trapezium has two and two aquals angles, and the scalen trapezium has the four inner angles unequal each other.
A parallelogram is a quadrilateral figure too but a parallelogram has all his sides parallels each others. Examples of parallelograms are the recntagle, the rhomb and the romboid.
In conclusion we can say that a trapezoid is a parallelogram when the opposites sides of the tifgure are totally parallels and the sumatory of the iner angles is equal to 180°.
The answer is probably C or D
The value of the x will be 25. The force involved vertically to the surface of an object per unit area is pressure.
<h3>What is pressure?</h3>
The force applied perpendicular to the surface of an item per unit area across which that force is spread is known as pressure.
The given data in the problem is;
The base of the block of metal is a rectangle of 20 cm by x cm.
The block exerts a force of 1500 newtons on the ground. The pressure on the ground is 3 newtons/cm²
The area of the rectangle;
A = L × B
A=20 × x
Hence the value of the x will be 25.
