<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>
Step-by-step explanation:
First add up the total amount of marbles in the bag.
14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.
Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).
7/31 ---> 0.22580645161 <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>
Lastly, round the decimal to the nearest hundredth.
0.22580645161 ---> <em>0.23</em>
<em>0.23</em> would be the odds of drawing a black marble.
Answer:
Area = 3.77 cm^2
Step-by-step explanation:
The diagram using the given statement is attached below
Diameter of larger circle is 10 so radius R1 = 10/2= 5
diameter of smaller circle is 7.6, radius (r1)= 3.8
We need to find the area of the shaded region
Area of the circle =
Area of annulus =
=
Area = 3.77 cm^2
