I think A might be wrong though
The constant rate of continuous growth, k, for this population is equal to 2.11935%. And the population will reach 250,000 people in 24.36 years.
For solving this question, you should apply the Population Growth Equation.
<h3>Population Growth Equation</h3>
The formula for the Population Growth Equation is:
Pf= future population
Po=initial population
r=growth rate
t= time (years)
STEP 1 - Find the constant rate of continuous growth, k, for this population.
For this exercise, you have:
Pf= future population= 185,000 in 2020.
Po=initial population =150,000 in 2010.
r=growth rate= ?
t= time (years)=2020-2010=10
Then,
![P_f=P_o*(1+\frac{R}{100} )^t\\ \\ 185000=150000\cdot \left(1+\frac{R}{100}\:\right)^{10}\\ \\ \left(1+\frac{R}{100}\right)^{10}=\frac{185000}{150000} \\ \\ \left(1+\frac{R}{100}\right)^{10}=\frac{37}{30}\\ \\ R=100\sqrt[10]{\frac{37}{30}}-100=2.11935\%](https://tex.z-dn.net/?f=P_f%3DP_o%2A%281%2B%5Cfrac%7BR%7D%7B100%7D%20%29%5Et%5C%5C%20%5C%5C%20185000%3D150000%5Ccdot%20%5Cleft%281%2B%5Cfrac%7BR%7D%7B100%7D%5C%3A%5Cright%29%5E%7B10%7D%5C%5C%20%5C%5C%20%5Cleft%281%2B%5Cfrac%7BR%7D%7B100%7D%5Cright%29%5E%7B10%7D%3D%5Cfrac%7B185000%7D%7B150000%7D%20%5C%5C%20%5C%5C%20%5Cleft%281%2B%5Cfrac%7BR%7D%7B100%7D%5Cright%29%5E%7B10%7D%3D%5Cfrac%7B37%7D%7B30%7D%5C%5C%20%5C%5C%20R%3D100%5Csqrt%5B10%5D%7B%5Cfrac%7B37%7D%7B30%7D%7D-100%3D2.11935%5C%25)
STEP 2 - Find the <em>t</em> for population 250,000 people.

<span>SALES: 5x² + 2x – 80
</span>- COST: 5x² – x + 100
= ------------------
PROFIT: 0x²+3x-180
(+3x because we subtracted a negative (-x), which is called adding, similarly taking away 100 from negative 80 is -180.)
Checking:
5x² + 2x – 80
5(500)²+2(500)-80 = 1,250,920
5x² – x + 100
5(500)² – (500) + 100= 1,249,600
Profit = 1,250,920 - 1,249,600 = 1,320
0(500)²+3(500)-180 = 1,320 YAY! {:-)
Double Checking:
5x² + 2x – 80
5(5000)²+2(5000)-80 = 125,009,920
5x² – x + 100
5(5000)² – (5000) + 100= 124,995,100
Profit = 125,009,920 - 124,995,100 = 14,820
0(5000)²+3(5000)-180 = <span>14,820</span> YAY! {:-)
We have to find the probability that one randomly selected card has a number less than 4 or a multiple of 9. There are numbers : 1 - 25. Numbers less than 4 are: 1, 2, and 3. Multiples of 9 that are less than 25 are : 9 ( 9 * 1 ) and 18 ( 9 * 2 ). So there are 5 favourable outcomes and 25 possible outcomes. The probability is: P ( A ) = ( number of favourable outcomes ) / ( number of possible outcomes ) = 5 / 25 = 1 / 5 = 0.2. Answer: The probability is 0.2 or 20 %<span>. </span>
