Why having a parabola with it's points calibrated is important?

Dominik [7]

Answer:

Because the points can often represent something, i.e if you used quadratics to model say the area of something, calibrating the turning point, will give you the given length needed for the dimension of that, plus the maximum area those dimensions can yield.

Evaluate the definite integral

Georgia [21]

$\displaystyle\int_{x=9}^{x=10}x\sqrt{x-9}\,\mathrm dx$

Let $y=x-9$ , so that $x=y+9$ and $\mathrm dx=\mathrm dy$ . The integral is then equivalent to

$\displaystyle\int_{y=0}^{y=1}(y+9)\sqrt y\,\mathrm dy=\int_0^1(y^{3/2}+9y^{1/2})\,\mathrm dy=\dfrac{32}5$

zubka84 [21]

Answer: 2017

Step-by-step explanation:

Given : The proportion of people that smoke : p=0.3

Margin of error : E= 0.02

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

The formula to calculate sample size ( if proportion is known) :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\\Rightarrow\ n=(0.3)(0.7)(\dfrac{(1.96)}{0.02})\\\\\Rightarrow\ n=2016.84approx2017$

Hence, the required minimum sample would be 2017.
