An average of 40 cars per hour arrive to be painted at a single-server GM painting facility. 95% of the cars require 1 minute to
Sindrei [870]

Answer:

2.719 minutes

Step-by-step explanation:

Step 1 :

We have to consider using the M/G/I /GD /∞/∞ Queuing system with the rate of arrival λ and the rate of service μ.

Since average of 40 cars arrive every hour at the painting facility, it follows that:

Arrival rate λ = 40cars /hour

= 40/60 cars/hour

=2/3 cars/hour

More, we were told that 95% of the cars require 1 minute to paint, 5% must be painted twice and require 2.5 minutes to paint, therefore, the average time to paint a car is given by

95/100x1 + 5/100 x 2.5 = 19/20 + 1/8 = 43/40min

It follows that:

Service rates μ = 40/43cars/min

Bill takes a loan of 9,000.00 at a 8% simple interrst rate for 6 years a.how much interest will he pay after 2 years? b. how muc
statuscvo [17]
To find the answer for A you add up the interest rate for 2 years which is 16% then find 16% of $9,000 which is $1,440 and that's his interest rate he will have to pay for 2 years. If you want to know how much he has to pay in total for 2 years you simply just add the interest rate $1,440to $9,000 and you get $10,440.

To find the answer for B you add up the interest rate for 6 years which is 48% then find 48% of $9,000 which is $4,320 and that's his interest rate he will have to pay for 6 years. If you want to know how much he has to pay in the total 6 years you simply just add the interest rate $4,320 to $9,000 and you get $13,320.

I hope that helped you.

Each graph shows a relation. The first and second numbers of each ordered pair in the relation are members of the set of real nu
Goshia [24]

Using it's concepts, we have that:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.
  • Since each value of the input is mapped to only one value of y, it is a function.

<h3>What are the domain and the range of a relation?</h3>

  • The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
  • The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.

Hence:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.

<h3>When does a relation represents a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.
