4vir4ik [10]

Answer:

number of people who will purchase next month = 250

the number of people who will purchase in 2 month = 325

Step-by-step explanation:

Data provided in the question:

people who purchase the plant's product during any month will not purchase it the next month = 30%

therefore, people who purchase the plant's product during any month will purchase next month = 70%

people who do not purchase the product during any month will purchase it the next month = 20%

Total number of people = 1000

Number of people who purchased this month = 100

Number of people who did not purchase = 1000 - 100 = 900

therefore,

the number of people who will purchase next month

= 70% of 100 + 20% of 900

= 0.70 × 100 + 0.20 × 900

= 70 + 180

= 250

now,

the number of people who will purchase in 2 month

= 70% of (number of people who will purchase next month) + 20% of (number of people who did not purchase next month)

= 70% of 250 + 20% of (1000 - 250)

= 0.70 × 250 + 0.20 × 750

= 175 + 150

= 325

En una tienda de ropa vas a comprarte una pantalones que están de 150 a 90 euros y una camiseta de 40 a 24 ¿ tienen el mismo por

uranmaximum [27]

Respuesta:

Sí, tienen el mismo descuento del 40%

Explicación paso a paso:

Dado :

PANTALÓN :

Precio inicial = 150

Precio con descuento = 90

Porcentaje de descuento en el precio:

(150 - 90) / 150 * 100%

60/150 * 100%

0,4 * 100

= 40%

CAMISA:

Precio inicial = 40

Precio con descuento = 24

Porcentaje de descuento en el precio:

(40-24) / 150 * 100%

16/40 * 100%

0,4 * 100

= 40%

Sí, tienen el mismo descuento del 40%

The number of errors in a textbook follow a Poisson distribution with a mean of 0.03 errors per page. What is the probability th

maksim [4K]

Answer:

The probability that there are 3 or less errors in 100 pages is 0.648.

Step-by-step explanation:

In the information supplied in the question it is mentioned that the errors in a textbook follow a Poisson distribution.

For the given Poisson distribution the mean is p = 0.03 errors per page.

We have to find the probability that there are three or less errors in n = 100 pages.

Let us denote the number of errors in the book by the variable x.

Since there are on an average 0.03 errors per page we can say that

the expected value is, $\lambda$ = E(x)

= n × p

= 100 × 0.03

= 3

Therefore the we find the probability that there are 3 or less errors on the page as

P( X ≤ 3) = P(X = 0) + P(X = 1) + P(X=2) + P(X=3)

Using the formula for Poisson distribution for P(x = X ) = $\frac{e^{-\lambda}\lambda^X}{X!}$

Therefore P( X ≤ 3) = $\frac{e^{-3} 3^0}{0!} + \frac{e^{-3} 3^1}{1!} + \frac{e^{-3} 3^2}{2!} + \frac{e^{-3} 3^3}{3!}$

= 0.05 + 0.15 + 0.224 + 0.224

= 0.648

The probability that there are 3 or less errors in 100 pages is 0.648.
