If a population consists of 10,000,000 people and census is taken, how many people are sampled?
Alex_Xolod [135]

According to question , population = 10,000,000 people & so census is taken , Hence 10,000,000  are sampled !

<u>Step-by-step explanation:</u>

Here we have , If a population consists of 10,000,000 people and census is taken, We need to find how many people are sampled . Let's find out:

The decision by consensus is a decision process that seeks not only the agreement of the majority of the participants, but also pursues the objective of resolving or mitigating minority objections to reach the most satisfactory decision. At the same time consensus means: a) a general agreement, b) a process to reach that agreement. Decision-making by consensus is primarily about the process. Since , census is taken that means all the available population is sampled ! According to question , population = 10,000,000 people & so census is taken , Hence 10,000,000  are sampled !

A sandwich shop loses $1.20 every time somebody buys a sandwich, but makes $1.80 every time somebody buys a drink. One day, the
Scrat [10]

Answer:

100(1.8) – 1.2x > 100

Step-by-step explanation:

Profit = Gain - loss

Gain:

$1.80 for each drink sold

So

G = 1.80d

In which d is the number of drinks sold.

One day, the shop sells 100 drinks.

This means that d = 100 and G = 100(1.8).

Loss:

$1.20 every time somebody buys a sandwich

x sandwiches are bought. So

L = 1.2x

Which inequality can you use to find possible numbers of sandwiches that it could sell and still make a profit of more than $100?

P > 100

P = 100(1.8) - 1.2x

So

100(1.8) – 1.2x > 100

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>
