Nitella [24]4 years ago

Answer:

Most likely C .

Step-by-step explanation:

The premium plan charges 20 dollars per cake. (+ 20) and $5 per child (5x) for pizza.

The premium plan would represent: 5x + 20

The basic plan would charge $6  per child for pizza.

This would be: 6x

In a equation when the cost of the premium plan is the same as the basic plan, 20 + 5x = 6x would be the best for modeling.

If A and B are mutually exclusive then: (A) P(A/B) = 0 (B) P(A/B) =P(B) (C) P(A or B) = 0 (D) P(A/B) = P(A) (E) none of the abov
Elis [28]

Answer:

A

Step-by-step explanation:

Two events are termed to be mutually exclusive if they cannot happen at the same time. This means that the probability of occurring at the same time is zero.

A is correct.

The probability of the two events happening at the same time is zero

B is incorrect

The probability of both happening at the same is not equal to the probability of B alone

C is incorrect

The probability of the union of the two is never equal to zero since they might occur at different times

D. Is incorrect

The probability of both happening at the same time is never equal to the probability of A alone

Halla el Perímetro y Area de las siguientes figuras: 1) Triángulo de lados 6 cm × 8 cm × 5 cm, con base en 8cm y altura de 3,73
omeli [17]

Answer:

1) El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²

2) La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²

Step-by-step explanation:

El perímetro es una medida de la distancia alrededor de una figura y el área da una idea de qué tanta superficie cubre dicha figura.

Entonces, el perímetro es la medida obtenida como resultado de la suma de los lados de una figura geométrica plana. Es decir, el perímetro es lo que mide el contorno de la figura.

El área de un triángulo es igual a base por altura dividido por 2.

Siendo r el radio de la circunferencia, el perímetro será calculado como:

P=2*π*r

y el área será:

A=π*r²

1) En este caso, el perímetro es calculado como:

P= 6 cm + 8 cm + 5 cm= 19 cm

Y el área del triángulo es calculada como:

A=\frac{base*altura}{2} =\frac{8 cm*3.73 cm}{2}

A= 14,92 cm²

<u><em>El triángulo tiene un perímetro cuyo valor es 19 cm y un área de 14,92 cm²</em></u>

2) Siendo el diámetro un segmento de recta que va desde un punto de la circunferencia a otro y pasa por el centro del círculo y l radio la distancia desde el centro del círculo hasta un punto de la circunferencia, entonces, el radio es la mitad del diámetro.

Siendo el diámetro de la circunferencia 4,5 cm, entonces el radio r tiene un valor de 2,25 cm.

Entonces el perímetro será calculado como:

P=2*π*2,25 cm

P= 14,14 cm

y el área será:

A=π*(2,25 cm)²

A= 15,90 cm²

<u><em>La circunferencia tiene un perímetro cuyo valor es 14,14 cm y un área de 15,90 cm²</em></u>
