Answer:
Number of people chosen in the sixth round is 729
Step-by-step explanation:
Given : For a game - 3 people are chosen in first round then each of three chooses 3 people in the second round ans so on.
To find : How many are chosen the sixth round.
Solution : We know,
In first round 3 people choose ⇒no. of people =3
In second round 3 people individually choose 3 people ⇒no. of people = 9
since the number of people chosen with a constant amount forming a geometric series
Geometric series - A sequence of numbers where each term after the first is found by multiplying the previous one by a fixed also called as common ratio.
General form:
and n-th term of geometric series is
where a - first term , r- common ratio and n-number of term
For the sixth round - a=3, r=3 , n=6
Therefore, number of people chosen in the sixth round is 729
A percentage is a way to describe a part of a whole. The percentage of increase from 50 to 90 is 80%.
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The percent of increase from 50 to 90 is,
= (90-50)/50 × 100%
= 40/50 × 100%
= 0.80 × 100%
= 80%
Hence, the percentage of increase from 50 to 90 is 80%.
