A parallelogram is a four-sided shape where the opposite sides are parallel to each other.
A rhombus is a parallelogram with the four sides equal.
Some of the properties of a rhombus are:
<span>1.) All sides are parallel and equal.
2.) Opposite angles are equal
3.) Consecutive angles add up to 180 degrees.
4.) <span>The diagonals bisect the angles.</span></span>

DochEvi [55]
Let x be the number of 20 ton cars

Then,
380<{15(22-x)+20x}<400
380<{330-15x+20x}<400
380<{330+5x}<400

Subtract 330 on both sides
50<5x<70

Divide both sides by 5;
10<x<14

Therefore, the range of 20 tonne cars is between 10 and 14 cars.

Nata [24]

Answer:

\frac{4}{9}

Step-by-step explanation:

First, we gather the data:

The model is a single M/M/1 landing strip with \mu = \frac{2}{3}

This based on the assumption that service times are exponential.

Then, we must find the maximum rate such that w_{q} \leq 3

Using the M/M/1 table, we find that:

w_{p}  = \frac{\rho }{(\mu (1 -\rho)  } \\ \frac{\lambda }{\mu (1 - \lambda  } \leq 3

if and only if

\lambda\leq \frac{3\mu ^{2} }{(1 + 3\mu) }

=\frac{4}{9}
