Mathematics
1 answer:
Cloud [144]3 years ago
4 0

Answer:

1. 9/10

2. 1/5

3. 4/9

4. 1

Step-by-step explanation:

The general equation of the line is:

(y - y0) = m ( x - x0), where "m" represents the slope is: (y1 - y0) / (x1 - x0).

1. From the statement we know that (x1, y1) = (18, 17) and (x0, y0) = (8,8)

Then the slope is:

m= (y1 - y0) / (x1 - x0) = (17 - 8)/(18 - 8) = 9/10.

The slope is 9/10.

2. From the statement we know that (x1, y1) = (8, 9) and (x0, y0) = (3,8)

Then the slope is:

m= (y1 - y0) / (x1 - x0) = (9 - 8)/(8 - 3) = 1/5.

The slope is 1/5.

3. From the statement we know that (x1, y1) = (15, 15) and (x0, y0) = (6,11)

Then the slope is:

m= (y1 - y0) / (x1 - x0) = (15 - 11)/(15 - 6) = 4/9.

The slope is 4/9.

4. From the graph, we know that the line passes through the points (-5, -4) and (-7, -6). So we know that (x1, y1) = (-5, -4) and (x0, y0) = (-7,-6).

Then the slope is:

m= (y1 - y0) / (x1 - x0) = (-4 - (-6))/(-5 - (-7)) = 2/2 = 1.

The slope is 1.

home security service. This private home security service guarantees to either dispatch one of their own five guards immediately
Irina-Kira [14]

Answer:

a.

The fraction of the time is incoming alarms directed to the police is 74.02%

b.

The home security company has to pay $3,197,665 the local police every month.

Step-by-step explanation:

As per the given data

Numbers of guards = 5 guards

Calls received per hour = 12 calls per hour

Activity time = 90 minutes

First, calculate the inter-arrival time

Inter-arrival time = Minutes in an hour / Numbers of calls received per hour = 60 minutes per hour / 12 calls per hour = 5 minutes

a.

First, calculate the ratio of activity time to inter-arrival time

Ratio = Activity time / Inter-arrival time = 90 minutes / 5 minutses = 18

Now calculate the probability of all 5 servers are busy using ratio of activity time to inter-arrival time

Probability = P_{Servers} ( ratio )

Probability = P_{5} ( 18 )

Probability = 0.7402

Probability = 74.02%

Hence the probability of incoming calls directed to the police is 74.02%

b.

First, calculate the loss of customers

Loss of customers = Probability x ( 1 / Servers )

Loss of customers = 74.02% x ( 1 / 5 )

Loss of customers = 0.7402 x 0.20

Loss of customers = 0.14804 per minute

Loss of customers = 0.14804 per minute x 24 x 60 x 30 = 6,395.33 calls per month

Now calculate the total loss

Total loss =  6,395.33 calls x $500

Total loss = $3,197,665
