The land area of a country is about 5.0 million square miles, and the population is about 600 million people. What is the avera

podryga [215]

Answer:

120 people/sq. mile

Step-by-step explanation:

Population Density is the concept of how "crowdy" a place is. The more the population density, the more crowded that place is.

The population density is found by dividing the "number of people" by the "land area" (in sq mile or sq km).

Here, it is given there are 600 million people, so

Number of People = 600,000,000

And, the land area is given as 5 million square miles, so

Land Area = 5,000,000 sq. miles

Hence,

Population Density = 600,000,000/5,000,000 = 120 people/sq. mile

without graphing what is the equation for THE LINE THAT PASSES THROUGH THE POINTS (-4, 3) AND (6 -2)

mojhsa [17]

Answer:

The answer to your question is: y = -1/2 x + 1

Step-by-step explanation:

Data

A (-4 , 3)

B (6, -2)

Formula

$m = \frac{y2 - y1}{x2 - x1} \\$

(y - y1) = m(x - x1)

Process

$m = \frac{-2 - 3}{6 + 4}$

$m= \frac{-5}{10}$

$m = -\frac{1}{2}$

(y - 3) = -1/2 (x + 4)

2(y - 3) = -1(x + 4)

2y - 6 = -x - 4

2y = - x - 4 + 6

2y = - x +2

y = -1/2 x + 1
