To find this out, turn the percent into a decimal:

45% -----> .45 (Divide by 100)

Then multiply the total minutes by the decimal percent:

1400 x .45 = 630

The final answer is, Maris has used 630 minutes.

Hope this helps!

Hello! To find out how many minutes she has used total, all you have to do is multiply the number of minutes by the percentage of the minutes that she has used. Maris has 1,400 minutes to use and has already used 45% of them. 1,400 * 45% (0.45) is 630. There. Maris has used 630 minutes.

A geometric progression has first term a ,common ratior and sum to infinity 6. A second

Sauron [17]

Answer:

a = $\frac{12}{7}$ , r = $\frac{5}{7}$

Step-by-step explanation:

The sum to infinity of a geometric progression is

$\frac{a}{1-r}$ ; | r | < 1

Thus for first progression

$\frac{a}{1-r}$ = 6 ( multiply both sides by (1 - r) )

a = 6(1 - r) → (1)

Second progression

$\frac{2a}{1-r^2}$ = 7 ← multiply both sides by (1 - r² )

2a = 7(1 - r² ) = 7(1 - r)(1 + r) ← difference of squares

2a = 7(1 - r)(1 + r) → (2)

Substitute a = 6(1 - r) into (2)

2(6(1 - r) = 7(1 - r)(1 + r)

12(1 - r) = 7(1 - r)(1 + r) ← divide both sides by (1 - r)

12 = 7(1 + r) = 7 + 7r ( subtract 7 from both sides )

5 = 7r ( divide both sides by 7 )

r = $\frac{5}{7}$

Substitute this value into (1)

a = 6(1 - $\frac{5}{7}$ ) = 6 × $\frac{2}{7}$ = $\frac{12}{7}$

Assume that the arrival of airplanes at a one-runway airport is a Poisson distribution with a mean rate of 8 planes per hour. Th

Delvig [45]

Answer:

Option b that is 1.33 is the right choice.

Step-by-step explanation:

Given:

Mean rate of arrival $(\lambda)$ = 8 planes/hr

Service time = $5$ minute/plane

Mean service rate $(\mu)$ = $\frac{60}{5}$ = $12$ planes/hr

Applying the concept Poisson-distributed arrival and service rates (exponential inter-arrival and service times)(M/M/1) process:

We have to find mean number of planes waiting to land that is mean number of customers in the queue .

Mean number of customers in queue $(L_q)$ .

⇒ $L_q=\frac{\rho \lambda}{\mu-\lambda}$

Considering, $\rho=\frac{\lambda}{\mu}$ , $\rho$ is also mean number of customers in service.

⇒ $L_q=\frac{ \lambda^2}{\mu(\mu-\lambda)}$

⇒ Plugging the values.

⇒ $L_q=\frac{8^2}{12(12-8)}$

⇒ $L_q=\frac{64}{48}$

⇒ $L_q=1.33$

So,

Mean number of planes in holding and waiting to land = 1.33
