The population density of Romania in 1997 given its area and the population is 95 people per square km.
<h3>What is the population density?</h3>
Population density is the number of people that live in a square kilometer of an area. It is determined by dividing total population by total area.
Population density = population / area
22.600,000 / 237301 = 95 people per square km

Answer:
P(A and B) is greater than 1 is never happened ⇒ C
Step-by-step explanation:
Two events are independent if the result of the second event is not affected by the result of the first event
If A and B are independent events, the probability of both events is the product of the probabilities of the both events P (A and B) = P(A) · P(B)
∵ The probability of any event is less than 1
∵ P(A) < 1
∵ P(A) > 
- That means P(A) is greater than half and less than 1
∴
< P(A) < 1
∵ P(B) < 1
∵ P(B) > 
- That means P(B) is greater than half and less than 1
∴
< P(B) < 1
∵ P(A and B) = P(A) . P(B)
- Remember the product of any fractions less than 1 is less than 1
∴
< P(A) . P(B) < 1
- That means any expression equals to P(A) . P(B) must be greater
than
and less than 1
∴
< P(A and B) < 1
∴ P(A and B) is greater than 1 is never happened
Answer: cos²(θ) + sin(θ)sin(e)
<u>Step-by-step explanation:</u>
sin (90° - θ)cos(Ф) - sin(180° + θ) sin(e)
Note the following identities:
sin (90° - θ) = cos(x)
sin (180° + θ) = -sin(x)
Substitute those identities into the expression:
cos(x)cos(x) - -sin(x)sin(e)
= cos²(x) + sin(x)sin(e)
