The number of visitors to an annual neighborhood carnival increased each year as shown in the table. Predict the number of visit

valentinak56 [21]

The average rate of change of the population from 2007 to 2012 is

$\dfrac{669-524}{2012-2007}=29$

which is to say that every five years you can expect 29 more visitors.

So if there were 607 visitors in 2010, then you could expect around 607+2*29=665 visitors in the year 2020.

Let x be a continuous random variable over [a,b] with probability density function f. Then the median of the x-values is that

natulia [17]

Answer:

The answer is " $\int e^{ax}\ dx=\frac{e^{ax}}{a}+c$ ".

Step-by-step explanation:

Please find the complete question in the attached file.

$\int^{m}_{a}\ f(x)\ dx=\frac{1}{2}\\\\f(x)=ke^{-kx}, \ [0, \infty]\\\\$

let m is the median

$so,\\\\ \int^{m}_{a}\ f(x)\ dx=\frac{1}{2}\\\\\to \int^m_0 k\cdot e^{-kx}=\frac{1}{2}\\\\\to [\frac{k\cdot e^{-kx}}{-k}]^m_0=\frac{1}{2}\\\\\to [- e^{-kx}]^m_0=\frac{1}{2}\\\\\to - e^{-km} +1=\frac{1}{2}\\\\\to e^{-km} =\frac{1}{2}\\\\\to e^{km} =2\\\\\to \ln(e^{km}) =\ln 2\\\\\to km= \ln \ 2\\\\\to m=\frac{\ln \ 2}{k}\\\\ \text{the answer is: } \\\\ \to \int e^{ax}\ dx=\frac{e^{ax}}{a}+c$
