est forms at the parts department counter. The parts clerk fills a request while the mechanic waits. On average everyday around 210 mechanics arrive in a random fashion over 10-hour working period. It takes the clerk average 2 minutes to fill a request. Assuming the service time and inter-arrival time is random and exponentially distributed. a) What is the average time mechanics spend waiting and having requests filled under the current system

Answer:

the average time spend is 0.111

Step-by-step explanation:

The computation of the average time spend is as follows;

Arrival rate is

= 210 ÷ 10

= 21 per hour

Now the service rate is

= 60 ÷ service time

= 60 ÷ 2 minutes

= 30 per minute

And, finally the average time spend is

= 1 ÷ (service rate - arrival rate)

= 1 ÷ (30 - 21)

= 0.111

Hence, the average time spend is 0.111

Find the equation of the line with a slope of 4 and passing through (0,3)
Simora [160]

4x -  y + 3 =0 is the equation of the line

Step-by-step explanation:

Given:

The slope of the line  =  5

The points through with the line passes = (0,3)

To Find:

The equation of the line  =?

Solution:

The equation  y = mx + b

where m is the slope and (0,b) is the y-intercept.

The slope is given which is m = 4 and a point (0,3)

Then you can use slope-point equation

y - y_o = m(x - x_o)

where (x_o,y_o) is the given point

y - (3) = 4(x - 0)

y - 3 = 4(x)

y = 4x - 22

y - 3 = 4x

4x - y + 3 = 0
