Hope this helps!
If not, I am sorry.
The first number is 27 and the second number is 45 so the ratio would be 27;45
Answer:
The equation i.e. used to denote the population after x years is:
P(x) = 490(1 + 0.200 to the power of x
Step-by-step explanation:
This problem could be modeled with the help of a exponential function.
The exponential function is given by:
P(x) = ab to the power of x
where a is the initial value.
and b=1+r where r is the rate of increase or decrease.
Here the initial population of the animals are given by: 490
i.e. a=490
Also, the rate of increase is: 20%
i.e. r=20%
i.e. r=0.20
Hence, the population function i.e. the population of the animals after x years is:
P(x) = 490(1 + 0.200 to the power of x
Answer:
The greater percent of cell phone ownership in Japan than the U.S was <u>13.7%</u>.
Step-by-step explanation:
Given:
About 543 out of every 1,000 people in United States owned a cell phone in 2003.
In japan,the are was 68 for every 100 people.
Now, to find the greater percent of cell phone ownership in Japan than the U.S.
So, to get the percent of people owned cell phone in United States:



Now, to get the percent of people owned cell phone in Japan:

So, to get the percent greater of cell phone ownership in Japan than the U.S we subtract the percent of people owned cell phone in United States from the percent of people owned cell phone in Japan:

Therefore, the greater percent of cell phone ownership in Japan than the U.S was 13.7%.
