Consider the Excel output attached.
The cumulative frequency are computed in the Excel sheet.
The cumulative frequency plot is also attached below.
From the cumulative frequency plot it can be seen that in the future most people will belong to a higher age group rather then the lower ones.
The 470 squirrels will be in 3 years, if a population of 280 flying squirrels in a town in Honduras is growing at a rate of 9% every 6 months.
Step-by-step explanation:
The given is,
280 flying squirrels
Growing at a rate of 9% every 6 months
Step:1
Formula to calculate the squirrels,
...........................(1)
where, A = Initial count
r = Growing rate
t = Time
From the given,
A = 280 squirrels
r = 9 % = 0.09
t = 6 ( Growing rate is given for 6 months, for 3 years 36 months available, so t = = 6)
From equation (1),
= (280)(1.6771)
= 469.588
Squirrels after 3 years, y ≅ 470 squirrels
( or )
Step:1
Year will be converted to months,
3 years = 36 months
For 6 months,
= (280 × 0.09)+280 = 305.2 squirrels
For 12 months,
= (305.2 × 0.09)+305.2 = 332.668 squirrels
For 18 months,
= (332.668 × 0.09)+332.668 = 362.608 squirrels
For 24 months,
= (362.608 × 0.09)+362.608 = 395.243 squirrels
For 30 months,
= (395.243 × 0.09)+395.243 = 430.815 squirrels
For 36 months,
= (430.815 × 0.09)+430.815 = 469.588 squirrels
Squirrels after 3 years, y ≅ 470 squirrels
Result:
The 470 squirrels will be in 3 years, if a population of 280 flying squirrels in a town in Honduras is growing at a rate of 9% every 6 months.
