3. Mateus recebe a visita do seu avô Pedro a cada 15 dias. João, o tio dele, o visita a cada 100
maxonik [38]

Answer:

Este acontecimento se repetirá 300 dias depois.

Step-by-step explanation:

Quando os eventos se repetirão no mesmo dia?

Cada evento tem uma frequência.

Eles ocorrem simultaneamente a cada x dias, e x é dado pelo MMC(Mínimo Múltiplico Comum) entre as frequência.

Neste problema:

A cada 15 dias o avô visita.

A cada 100 dias o tio visita.

A cada 12 dias vai à praia.

Quantos dias depois este acontecimento se repetirá?​

Os três no mesmo dia vão se repetir após x dias, em que x é dado pelo MMC de 15, 100 e 12

MMC de 15, 100 e 12

Fatorando simultâneamente estes valores:

15 - 100 - 12|2

15 - 50 - 6|2

15 - 25 - 3|3

5 - 25 - 1|5

1 - 5 - 1|5

1 - 1 - 1

Então:

mmc(15,100,12) = 2*2*3*5*5 = 300

Este acontecimento se repetirá 300 dias depois.

The Apple, Inc. sales manager for the Chicago West Suburban region is disturbed about the large number of complaints her office
ankoles [38]

Answer:

0.6856

Step-by-step explanation:

\text{The missing part of the question states that we should Note: that  N(108,20) model to } \\ \\  \text{ } \text{approximate the distribution of weekly complaints).]}

Now; assuming X = no of complaints received in a week

Required:

To find P(77 < X < 120)

Using a Gaussian Normal Distribution (\mu =108, \sigma = 20)

Using Z scores:

Z = \dfrac{77-108}{20} \\\\ Z = -\dfrac{35}{20} \\ \\  Z  -1.75

As a result  X = 77 for N(108,20) is approximately equal to  to Z = -1.75 for N(0,1)

SO;

Z = \dfrac{120-108}{20} \\ \\  Z = \dfrac{12}{20}\\ \\  Z = 0.6

Here; X = 77 for a N(108,20) is same to Z = 0.6 for N(0,1)

Now, to determine:

P(-1.75 < Z < 0.6) = P(Z < 0.6) - P( Z < - 1.75)

From the standard normal Z-table:

P(-1.75 < Z < 0.6) = 0.7257 - 0.0401

P(-1.75 < Z < 0.6) = 0.6856
