A population of 110,000 grows 3% per years 15 years. How much will the population. How much will the population be after 15 year
bonufazy [111]

Answer:

The population be after 15 years is 171376.

Step-by-step explanation:

Given : A population of 110,000 grows 3% per years 15 years.

To find : How much will the population be after 15 years?

Solution :

Exponential growth population model is given by,

P(t)=P_o(1+r)^t

Where,

P(t) is the population at time (t)

P_o=110,000 is the initial value of the population

r=3%=0.03 is the annual rate of growth

t=15 is the time in years.

Substitute the value,

P(t)=110000(1+0.03)^{15}

P(t)=110000(1.03)^{15}

P(t)=110000\times 1.5579

P(t)=171376.41

Therefore, the population be after 15 years is 171376.

approximately 3 people out of every 25 are left handed about how many people would you expect in a group of 140 people
kati45 [8]
Okay so 3/25 (OF) 140 you'd have to do 140 divided by 25 then times that answer by 3. 140 divided by 25 = 5.6. 5.6 x 3 = 16.8. You can't have 16.8 people so you round it which makes it 17 people.

vredina [299]

Answer:

5400

Step-by-step explanation:

so 90% of 850 is 765 (0.90x850)

765 is 10 years

so 1 year is 765/10 = 76.5 per year. So 76.5x59 = 4,513.5 add the initial ammount and you got 5,363.5 in the nearest hundredth you get 5400
