A circle is centered at $O$ and has an area of $48 \pi.$ Let $Q$ and $R$ be points on the circle, and let $P$ be the circumcente

nikklg [1K]

Answer:

Area of Triangle QRP = 3 $\sqrt{3}$

Step-by-step explanation:

According to Question , We have a circle With Centre 'O' & Area 48 $\pi$ .

Area Of Circle = 48 $\pi$

$\pi$ $r^{2}$ = 48 $\pi$

r = $\sqrt{48}$

Now We Have Two Points Given On Circle Q & R , P Is Circumcentre Of Triangle QRO .

Thus A Circle Can Also Be Formed with Centre P . ( See attachment For Diagram )

Now The Diameter of Circle With Centre P = Radius Of Circle with Centre O

so Radius Of Circle With Centre P( $r_{2}$ ) = $\frac{\sqrt{48}}{2}$

Now We Have To Find Area Of Equilateral Triangle .

A = $\frac{\sqrt{3}}{4} r_{2} ^{2}$

A= $\frac{\sqrt{3} }{4} * \frac{\sqrt{48} }{2}*\frac{\sqrt{48} }{2}$

The Area Of PQR is = 3 $\sqrt{3}$

labwork [276]

Answer:

99.8 %

Step-by-step explanation:

μ = 75 and σ = 5

The information about 68-95-99.7 rule is:

μ ± 0,5σ 68.3 % of all values will be in the interval

[ μ - 0,5σ ; μ + 0,5σ ] [ 72.5 : 77,5 ]

μ ± 1σ 95 % of all values will be in the interval

[ μ - 1σ ; μ + 1σ ] [ 70 : 80 ]

And:

μ ± 1,5σ 99.7 % of all values will be in the interval

[ μ - 1.5σ ; μ + 1.5σ ] [ 67,5 : 82,5 ]

And still 85 is bigger than 82,5 we can conclude that approximately 99.8 % will be smaller than 85 and then "the relative frecuency of rates less than 85 is very high 99.8 %
