Answer:
The explicit formula for the geometric sequence is
.
Step-by-step explanation:
By definition of geometric sequence, we should use the following expression:
,
(1)
Where:
- First term.
- Geometric rate.
- Position of the element within the series.
If we know that
and
, then the explicit formula for the geometric sequence is:

The explicit formula for the geometric sequence is
.
In the given question all the information's are provided based on which the answer to the question can be easily deduced. It is already given that the population of the world in the year 2002 was estimated to about 6 billion. Among them 20% of the people lived on an an income of less that $1 per day.Firstly let us convert 6 billion from words to numbers.
6 billion = 6000000000
Now
Number of people earning less that $1 per day = (20/100) * 6000000000
= 6000000000/5
= 1200000000
So the number of people earning less than $1 per day is 1200000000
Answer:
1/221=0.0045
Step-by-step explanation:
8000/ 2 = x/16
cross multiply
2x = 8000 * 16
2x = 128000
x = 128000/2
x = 64000 crocus flowers
Answer:
D. No comma because the total probability is not equal to 1.
Step-by-step explanation:
Given the distribution:

The sum of the probabilities

Therefore, the distribution is not a probability distribution because the total probability is not equal to 1.
The correct option is D.
