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

Somebody help<br> 7x - [4x-3(x-1)]=x+ 12

Georgia [21]

Answer:

Step-by-step explanation:

Simplificando

7x + -1 [4x + -3 (x + -1)] = x + 12

Reordenar los términos:

7x + -1 [4x + -3 (-1 + x)] = x + 12

7x + -1 [4x + (-1 * -3 + x * -3)] = x + 12

7x + -1 [4x + (3 + -3x)] = x + 12

Reordenar los términos:

7x + -1 [3 + 4x + -3x] = x + 12

Combinar términos semejantes: 4x + -3x = 1x

7x + -1 [3 + 1x] = x + 12

7x + [3 * -1 + 1x * -1] = x + 12

7x + [-3 + -1x] = x + 12

Reordenar los términos:

-3 + 7x + -1x = x + 12

Combinar términos semejantes: 7x + -1x = 6x

-3 + 6x = x + 12

Reordenar los términos:

-3 + 6x = 12 + x

Resolviendo

-3 + 6x = 12 + x

Resolviendo para la variable 'x'.

Mueva todos los términos que contengan x hacia la izquierda, todos los demás términos hacia la derecha.

Agrega '-1x' a cada lado de la ecuación.

-3 + 6x + -1x = 12 + x + -1x

Combinar términos semejantes: 6x + -1x = 5x

-3 + 5x = 12 + x + -1x

Combinar términos semejantes: x + -1x = 0

-3 + 5x = 12 + 0

-3 + 5x = 12

Agrega '3' a cada lado de la ecuación.

-3 + 3 + 5x = 12 + 3

Combinar términos semejantes: -3 + 3 = 0

0 + 5x = 12 + 3

5 veces = 12 + 3

Combinar términos semejantes: 12 + 3 = 15

5 veces = 15

Divida cada lado por '5'.

x = 3

Simplificando

x = 3

A set of numbers satisfies Benford’s Law if the probability of a number starting with digit d is P(d) = log(d + 1) – log(d).

irakobra [83]

Interpreting the graph and the situation, it is found that the values of d that can be included in the solution set are 1 and 4.

----------------------

According to Benford's law, the probability of a number starting with digit is d is:

$P(d) = \log{(d + 1}} - \log{d}$

A number can start with 10 possible digits, ranging from 1 to 9, which are all integer digits.

Thus, d can only assume integer digits.

In the graph, the solution is d < 5.
The integer options for values of d are 1 and 4.
For the other options that are less than 5, they are not integers, so d cannot assume those values.

To estimate the height of a totem pole, Jorge uses a small square of plastic. He holds the square up to his eyes and walks backw

Ghella [55]

The height of the pole is 6.50 meters

<h3>How to calculate the height?</h3>

To calculate the height of the pole, we will use of the following equivalent ratios.

By Pythagoras theorem, we have:

$x ^2 = 2^2 + 3^2\\\\x ^2 = 4 + 9\\\\x = \sqrt{13}$

So, we have:

$h = \dfrac{\sqrt{13}^2 }{2} \\\\h = \dfrac{13}{2}\\\\h = 6.5$

Hence, the height of the pole is 6.50 meters
