The population of California =
people.
Land area of California =
.
We have to determine the average number of people per square kilometer.
Average number of people per square kilometer =
Land area of California
Population of California
= ![4.05 \times 10^5 \div 2.52 \times 10^7](https://tex.z-dn.net/?f=4.05%20%5Ctimes%2010%5E5%20%5Cdiv%202.52%20%5Ctimes%2010%5E7)
= ![1.6 \times 10^{-2}](https://tex.z-dn.net/?f=1.6%20%5Ctimes%2010%5E%7B-2%7D)
Therefore, the average number of people per square kilometer is
.
It is represented in scientific notation as Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
Answer:
3 / 8
Step-by-step explanation:
From the tree diagram provided :
Required outcome = atleast two consecutive tails :
(HTT) ; (TTH) ; (TTT) = 3
TOTAL POSSIBLE OUTCOMES = 8
PROBABILITY = REQUIRED OUTCOME / TOTAL POSSIBLE OUTCOMES
HENCE ;
P(ATLEAST TWO TAILS IN A ROW) = 3 / 8
1/2 is less than 1
4/3 is more than 1
