What are two step equations
miskamm [114]
2 step equations are equations that require 2 steps to solve it.

For example, 2x + 5 = 3x + 6

To solve for x, we must isolate it.

First subtract 2x on both sides, which is ONE step.

2x + 5 = 3x + 6
-2x         -2x

5 = x + 6

The we must subtract 6 from both sides of the equation, which makes is the second step.

5 = x + 6
-6       -6

-1 = x 

-1 would be the answer and we only used 2 steps to solve it.

3. Students arrive at an ATM machine in a random pattern with an average inter-arrival time of 3 minutes. The length of transact
svp [43]

Answer:

The probability that a student arriving at the ATM will have to wait is 67%.

Step-by-step explanation:

This can be solved using the queueing theory models.

We have a mean rate of arrival of:

\lambda=1/3\,min^{-1}

We have a service rate of:

\mu=1/2\,min^{-1}

The probability that a student arriving at the ATM will have to wait is equal to 1 minus the probability of having 0 students in the ATM (idle ATM).

Then, the probability that a student arriving at the ATM will have to wait is equal to the utilization rate of the ATM.

The last can be calculated as:

P_{n>0}=\rho=\dfrac{\lambda}{\mu}=\dfrac{1/3}{1/2}=\dfrac{2}{3}=0.67

Then, the probability that a student arriving at the ATM will have to wait is 67%.
