Each August a restaurant rent is adjusted to the cost of living index. The rent has $1,550 a month, the cost-of-living index for

gulaghasi [49]

Answer:
new rent = $1607.35

Explanation:
Assume that the original rent is x

We are given that the rent increased by 3.7%.
This means that:
new rent = x + 3.7% x
new rent = x + 0.037 x

We are given that x = 1550, therefore:
new rent = 1550 + 0.037(1550)
new rent = 1550 + 57.35
new rent = $1607.35

Hope this helps :)

24.2 / 0.2 can someone explain please?

tresset_1 [31]

When dividing decimals, you move them over until the denominator is a whole number, so 0.2 to 2. The divisor's decimal is also moved over, so 24.2 to 242.

Now we have 242/2. I think you can take it from there.

El 10% de los huevos de un supermercado están rotos, haya la probabilidad de que un cliente que compra media docena de huevos en

crimeas [40]

Answer:

La probabilidad de encontrar como mucho un huevo roto es 0,8857.

Step-by-step explanation:

Podemos calcular la probabilidad de econtrar un huevo roto usando la ecuación de distribución binomial:

$P (x) = \left(\begin{array}{c}n&x\end{array}\right)p^{x}(1 - p)^{n-x}$

En donde:

p: es la probablidad de encontrar huevos rotos = 10% = 0,1

x: es el número de éxitos

n: es el número de ensayos = 6 (media docena de huevos)

Ahora, como nos piden la probabilidad de enontrar como mucho un huevo roto, esto quiere decir que debemos encontar la suma de la probablidad de encontar un huevo roto con la probabilidad de encontrar ninguno roto:

$P = P(0) + P(1)$

$P = \left(\begin{array}{c}6&0\end{array}\right)0,1^{0}(1 - 0,1)^{6-0} + \left(\begin{array}{c}6&1\end{array}\right)0,1^{1}(1 - 0,1)^{6-1} = 0,5314 + 0,3543 = 0,8857$

Entonces, la probabilidad de encontrar como mucho un huevo roto es 0,8857.

Espero que te sea de utilidad!
