Katyanochek1 [597]

Answer:

Do you mean 2x<2 or

X <2 or do you mean x²<2

Step-by-step explanation:

If your question is X²<2

Then

Total outcomes=5

Possible outcomes=3(-1,0,1)

Probability of x²<2=3/5

If your question means probability of2x<2

Then

Total outcomes=5

Possible outcomes=3 (-2,-1,0)

Probability of 2x<2=3/5

If your question means x< 2

Total outcomes=5

Possible outcomes=4 (-2,-1,0,1)

Probability of x <2 =4/5

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of
Romashka [77]

Answer:

51

Step-by-step explanation:

A = Surface area of the Earth = 1.5\times 10^8\ \text{km}^2

Total number of people on Earth = 7.594 billion as of 2018 = 7.594\times 10^9

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}

\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}

\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}

So, 51 people will inhabit each square km of land area.
