Answer:
x=2
Step-by-step explanation:
Primero, necesitamos calcular <<a>>
Sabemos que AD=BC y AB=CD porque lados opuestos congruentes
Entonces, vamos a calcular <<a>>.
Usamos AD y BC
2a-1=4a-15
suma 15 a ambos lados
2a+14=4
añada 2 en ambos lados
14=2a
divida
7=a
Ahora, usamos esta información para calcular <<x>>
Usamos CD=AB
2a-8=4x-2
pero sabemos que <<a>> es 7
entonces:
14-8=4x-2
6=4x-2
8=4x
2=x
<<x>> es 2

Answer:
Step-by-step explanation:
1) Sample space - the set of all possible outcomes for an experiment
2) Theoretical probability - A ratio representing the likelihood of an event
3) Uniform probability model - A probability model in which each of the outcomes in the sample space are equally likely, or have the same probability

Answer: 169.2cm
Step-by-step explanation:
From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.
To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:
= 56.4cm × 3
= 169.2cm
