What is the rate of change between the interval of x = 3 pi over 2 and x = 2π?

galina1969 [7]

Check the picture below.

$\bf slope = m = \cfrac{rise}{run} \implies 
\cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby 
\begin{array}{llll}
average~rate\\
of~change
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
x_1=\frac{3\pi }{2}\\
x_2=2\pi 
\end{cases}\implies \cfrac{f(2\pi )-f\left( \frac{3\pi }{2} \right)}{2\pi -\frac{3\pi }{2} }\implies \cfrac{3-1}{\frac{4\pi -3\pi }{2}}\implies \cfrac{2}{\quad \frac{\pi}{2}\quad }\implies \cfrac{4}{\pi }$

Rasek [7]

Answer:

0.6604

Step-by-step explanation:

Given that a market research firm knows from historical data that telephone surveys have a 36% response rate.

Sample size of random sample = 280

We know for samples randomly drawn of large size sample proportion follows a normal distribution with mean= sample proportin and std error

= $\sqrt{\frac{pq}{n} }$

Substitute p = 0.36 and q = 1-0.36= 0.64

p follows N with mean = 0.36 and std dev = $\sqrt{\frac{0.36*0.64}{\sqrt{280} } } \\=0.0287$

Using normal distribution values we can find\

$P(33.5p.c. < p < 39pc)\\= P(0.335$
