The area of the scale drawing will be:
600 square feet.
Step-by-step explanation:
The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet.
It is given that:
The scale factor of a room for a scale drawing is 2.3.
The length of the room according to the scale drawing will be:
46÷2.3=20 feet
and the width of the room according to scale drawing will be:
69÷2.3=30 feet
We know that the wall is in the shape of a rectangle.
This means that the area of scale drawing will be:
Length×Width
= 20×30
= 600 square feet.

I'm a sample bag of m&m's there are 5 brown, 6 yellow, 4 blue, 3 green, and 2 orange. What is the probability of getting 3 y
Vsevolod [243]
There are a total of 5+6+4+3+2=20 M&Ms in the bag.  Since there are 6 yellow M&Ms in the bag, there's a 6/20 probability that the first M&M will be yellow.  Then, there are 5 more yellow M&Ms and 19 more total M&Ms in the bag, so there is a 5/19 chance the next M&M will be yellow.  Finally, there are 4 more yellow M&Ms in the bag and 18 total M&Ms, so there is a 4/18 chance the last M&M will be yellow.

Multiplying these together, we have:

(6*5*4)/(20*19*18)

This simplifies to:

1/57

Therefore, there is a 1/57 probability that all M&Ms will be yellow.

Supongamos que estás en el infierno y el diablo te reta a un juego. Él piensa en un número natural.Cada día, tú tendrás una opor
Blababa [14]

Answer:

En síntesis, se inicia con el número natural más pequeño en el primer y se prosigue con los números siguientes en caso de no dar con n, de modo que el participante pasará en el infierno únicamente n días, algo pequeño en comparación con la eternidad.

Step-by-step explanation:

Los números naturales comprenden el subconjunto más pequeño de los números reales conformado por los siguientes elementos:

\mathbb{N} = \{1,2,3,4,...\}

Sea n \in \mathbb{N} el número que tiene el diablo en su mente, tal que n \geq 1. Comenzamos el primer día con 1, si este no corresponde con n. Entonces se utiliza 2 al día siguiente y este no corresponde, se emplea al día siguiente y así sucesivamente hasta conseguir n.

En síntesis, se inicia con el número natural más pequeño en el primer y se prosigue con los números siguientes en caso de no dar con n, de modo que el participante pasará en el infierno únicamente n días, algo pequeño en comparación con la eternidad.
