Answer:
Probability is 64%
Step-by-step explanation:
Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R
r = 3 inches
R = 5 inches
Step 1 : To calculate the area of shaded region.
Area of circle =
⇒ Area =
= square inches
Step 2 : To calculate the area of larger circle.
Area of circle =
⇒ Area =
= square inches
Step 3 : Calculate the probability that a point chosen from shaded region
Probability = Area of shaded region/Area of larger circle.
= /
=
= 0.36 = 36%
Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.
Probability = 1 - 0.36
= 0.64 = 64%
Hence the probability is 64%

Answer:
x=2, z=4, y=-6
Step-by-step explanation:
Add
<u>-9x-y+2z= -4</u>
<u>-6x+y+5z= 2</u>
-9x-6x is -15x
-y+y is 0
2z+5z is 7z
-4+2 is -2
So the equation now looks like this: -15x+7z=-2
Subtract
<u>-6x+y+5z= 2</u>
<u>-4x+y+5z= 6</u>
So the equation will look like this:
<u>-6x+y+5z= 2</u>
<u>-(-4x+y+5z= 6)</u>
-6x+4x is -2x
y-y is 0
5z-5z is 0
2-6 is -4
So the equation now looks like this: <u>-2x=-4</u>
You can find x by dividing -2 on both sides:
<u>x=2 </u>
So 2 is x
Now you can substitute x into 2
-15(2)+7z=-2
-30+7z=-2
7z=28
Divide 7 on both sides:
<u>z=4</u>
So now you can substitute z into 4 (For any of the three equation)
-4(2)+y+5(4)=6
-8+y+20=6
20 minus 8 is 12
y+12=6
Subtract 12 on both sides:
y=-6
So the answers are
x=2, z=4, y=-6
Hope this helps!
