The population of the small town of Parks in 2000 was estimated to be 3,901 people with an annual rate of decrease of about 1.8%

trasher [3.6K]

<u>Answer-</u>

<em>The estimated population in 2013 is </em><em>3081.</em>

<u>Solution-</u>

This can be represented as exponential decreasing function,

$y=a(1 - r)^t$

Where,

a = starting amount
r = rate
t = years

Putting the values,

$y=3901(1 - 0.018)^{13}$

$=3901(0.982)^{13}$

$=3901\times 0.7897$

$=3080.62$

As population can not be in fraction, so after rounding off the estimated population in 2013 is 3081.

15.12 is what percent of 12?

Llana [10]

Answer:

<h2>126%</h2>

Step-by-step explanation:

$\bold{METHOD\ 1}\\\\\begin{array}{ccc}15.12&-&p\%\\\\12&-&100\%\end{array}\qquad\text{cross multiply}\\\\\\12p=(15.12)(100)\\12p=1512\qquad\text{divide both sides by 12}\\p=126$

$\bold{METHOD\ 2}\\\\p\%=\dfrac{p}{100}\\\\p\%\ of\ 12\ is\ equal\ to\ 15.12:\\\\\dfrac{p}{100}\cdot12=15.12\\\\\dfrac{12p}{100}=15.12\qquad\text{multiply both sides by 100}\\\\12p=1512\qquad\text{divide both sides by 12}\\\\p=126$
