Answer:
Part 1. 0.9259 % per year
Part 2. P = 281.4e^(0.009 259t); 338.6 million
Step-by-step explanation:
Data:
P₀ = 281.4 million
P = 308.7 million
Part 1. Growth rate
t = 2010 - 2000 = 10 yr
P = P₀e^(rt)
308.7 = 281.4e^(10r)
e^(10r) = 1.0970
10r = ln1.0970
r = (ln1.0970)/10 = (0.092 59)/10 = 0.009 259
r = 0.9259 % per year
The 10-year continuous growth rate is 0.9259 % per year.
Part 2. Population model
The population model is
P = 281.4e^(0.009 259t)
where P is in millions and t is the number of years since 2000.
By 2020,
P = 281.4e^(0.009 259 × 20) = 281.4e^0.1852 = 281.4 × 1.203
P = 338.6 million
The estimated population in 2020 is 338.6 million.
Answer:
11 min and 525 words
Step-by-step explanation:
I put 140 words/ 4 mins and simplified it to 35 words /1 min
Doing so i plug in what was given and used cross multiply and divid :D
Answer:
Step-by-step explanation:
mean- add up all numbers and divide by how many numbers there are
median- the middle number out of the list of numbers
mode- the number you see most often
For the distributive property, multiply the number outside the parentheses by each term inside the parentheses.
1/6 x 12s = 2s
1/6 x 6 = 1
Now combine them to get the final answer: 2s + 1
We have that
the first balance indicates--------> 10 g
the second balance indicates--------> 0 g
the third balance indicates--------> 7.5 g
therefore
the <span>mass of the chick is (10+0+7.5)----> 17.5 g
the answer is
17.5 g</span>
