Answer:

100 resident/km

Step-by-step explanation:

In order to find the population density, we have to calculate the area of the township first.

We know that:

L = length = 5 km

W = width = 4 km

So the area of the township is

A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km

2

Now we can find the population density by using

d=\frac{N}{A}d=

A

N

where N is the number of residents, and A is the area.

Substituting N = 2000, we find:

d=\frac{2000}{20}=100 res./km^2d=

20

2000

=100res./km

2

so, 100 residents per kilometer squared

Calcula el ancho de un terreno rectangular si el largo mide 20 metros y la superficie es de 280 metros cuadrados
Anna35 [415]

Answer:14 m

Step-by-step explanation:

Dada

larga l=20\ m

superficie A=280\ m^2

Suponga que el ancho es w

La superficie está dada por el producto de la longitud y la anchura.

\therefore A=lw\\\Rightarrow 280=20\times w\\\Rightarrow w=14\ m

Por lo tanto, el ancho es de 14 m.

Describe how the variability of the distribution changes as the sample size increases. As the sample size increases, the variabi
wolverine [178]

Answer:

As the sample size increases, the variability decreases.

Step-by-step explanation:

Variability is the measure of actual entries from mean.  The less the deviations the less would be the variance.

For a sample  of size n, we have by central limit theorem the mean of sample follows a normal distribution for random samples of large size.

X bar will have std deviation as \frac{s}{\sqrt{n} }

where s is the square root of variance of sample

Thus we find the variability denoted by std deviation is inversely proportion of square root of sample size.

Hence as sample size increases, std error decreases.

As the sample size increases, the variability decreases.

The black graph is the graph of y=f(x). Choose the equation for the red graph.
Makovka662 [10]

Answer:

y-1 = f(x)

Step-by-step explanation:

Here, we want to choose the equation for the ref graph

The red graph as we can see is above the black

This means it is more positive

The difference between the two is just 1 unit

By the addition of 1 to the y-value of the black graph, we get the red

Thus, we have that;

y- 1 = f(x)
