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%.

4/5% of 500 rounded to the nearest hundreds

ra1l [238]

Answer:

I am not quite sure what you are asking so i will give you the answer for 4.5% and 45%.

4.5% of 500= The answer i got for this one is 4 so i am assuming you mean 45.

45% of 500= 225 but rounded would be 200

A painter is going to apply a special coating to a triangular metal plate on a new building. Two sides

viva [34]

Answer:

$Area = 90.03cm^2$

Step-by-step explanation:

Given

$s_1 = 14.9$

$s_2 = 14.7$

$\theta = 124$ --- angle in between

Required

The area of the plate

Since $\theta = 124$ is between $s_1$ and $s_2$

The area is:

$Area = \frac{1}{2} * s_1 * s_2 * \sin(\theta)$

$Area = \frac{1}{2} * 14.9 * 14.7 * \sin(124.7)$

$Area = \frac{1}{2} * 14.9 * 14.7 * 0.8221$

$Area = 90.03cm^2$
