Answer:
Mmmm tricky but I'll try..
take away 4 apples from the basket with 9 and place it in the one with 1 apple
then take away one apple from the one with 6 and place it in the basket with 4
And now you have 5 apples in each basket
Happy now?
Is it .236 cuz then you would round it to,.24
When dividing 0.006 divided by 0.024 it becomes 0.025, i did it by calculator so dont give me credit for this lol
Answer:
Population in 2100 is 17.99 billion.
Step-by-step explanation:
The population of the world in 2020 = 7.8 billion.
The growth rate = 1.05%
Now find the population after 2100. Use the below formula to find the population.
Population in 2100 = Population of 2020 (1 + growth rate)^n
Population in 2100 = 7.8 (1 + 0.0105)^80
Population in 2100 = 17.99 billions.
Now, find the growth rate in 2100.
dN/dt = [r N (K – N) ] / K
r = Malthusian parameter
K = carrying capacity.
Now divide both sides by K, now x = N/K then do the differential equation.
dx/dt = r x ( 1- x)
Now integrate, x(t) = 1/ [ 1 + (1/x – 1) c^-rt
From the first equation = dN/dt = (13 – 7.8) / 80 = (r × 7.8×(13 – 7.8) / 12
0.065 = (r × 7.8× 5.2) / 12
0.065 = r × 3.38
r = 1.92%
(2,3) would be your answer I believe
Hope it helped stay safe xx
