Answer:

0.044

Step-by-step explanation:

n=9,p=0.9, x =6.

Apply Binomial probability we get

Sum P(x)=C(n,x) p^{x} (1-p)^{n-x} for x=6

Putting in the formula ,

we get

P(x) = C(9,6) 0.9^{6} 0.1^{3}

84 X 0.531441 X 0.001

= 0.044

Karina is designing a logo on a coordinate plane. The logo is a square whose area is 200 square units. She places a circle in th
Katarina [22]

Answer:

D

Step-by-step explanation:

To find the percentage we must first find the area of the circle:

We can find the radius of the circle using the distance formula;

⇒ d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}

⇒ r = \sqrt{(6.3 - 0)^{2} + (1.6 - 0)^{2}}

⇒ r = 6.5

Now we calculate the area;

⇒ A = \pi r^{2}

⇒ A = \pi (6.5)^{2}

⇒ A = \frac{169}{4}\pi

To get the percentage we divide the area of the circle by the square’s are and multiply by 100;

⇒ Percentage = \frac{42.25\pi }{200} * 100

⇒ Percentage = 66 (2sf)
