tresset_1 [31]

Answer:

The probability of selecting a solid black marbles both times;

P = 9/100

Attached is the completed question;

Step-by-step explanation:

Number of solid black marbles = 3

Total number of marbles = 10

The probability of selecting a solid black marble;

P1 = 3/10

With the assumption that the marbles are replaced before next selection.

The probability of selecting a solid black marbles both times;

P = P1 × P1 = 3/10 × 3/10 = 9/100

P = 9/100

What is the radius of the following circle?
lara [203]

Answer:

The radius is: 2\sqrt{3}

Step-by-step explanation:

The equation of a circle in center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is at the point (h, k) and the radius is "r".

So, given the equation of the circle:

x^2+y^2=12

You can identify that:

r^2=12

Then, solving for "r", you get that the radius of this circle is:

r=\sqrt{12}\\\\r=2\sqrt{3}
