The cardinality of a sample space means the size of the sample space.
Event A: There are only 2 possible outcomes. Cardinality is 2.
Event B: There are 5 possible outcomes. Cardinality is 6.

Answer:

Cardinality of Event A=2 and of Event B=6

Step-by-step explanation:

Event A:Flipping a coin

There are only 2 possible outcomes (head or tail).

Hence, cardinality is 2.

Event B: Rolling a standard number cube

There are 6 possible outcomes (1,2,3,4,5 or 6).

Hence, cardinality is 6.

Hence, Cardinality of Event A=2 and of Event B=6

Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-7, -5), B(-
sergey [27]

The length of side CD is equal to 11 units.

Given coordinates of rectangle are A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5)

We are require to find the length of side CD.

Rectangle is a two dimensional figure whose two opposite sides are equal to each other. Distance between two coordinates is the equal to length of a side.

We know that the distance means how far two points are located.

Coordinates of  A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5).

Distance=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } where (x_{1} ,y_{2} )(x_{2} ,y_{2} ) are the coordinates of two ends of a line.

CD=\sqrt{(-5-6)^{2} +(-4+4)^{2} }

=\sqrt{11^{2}+0^{2}  }

=\sqrt{121}

=11 units.

Hence the length of side CD is 11 units.

If trapezoid ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie?
Dmitrij [34]
A is the point (-4, 1)

i) reflection over the y-axis projects a point (a, b) to (-a, b):

(-4, 1) is projected to (4, 1), 

ii) reflection over the x axis projects a point (a, b) to (a, -b):

(4, 1) is projected to (4, -1),

iii) rotation 180 degrees: projects (a, b) to (-a, -b):

so (4, -1) is projected to (-4, 1)


Answer: A'(-4, 1)
