Since each of the 4 balls are equally likely, their probability is:
From , we have:
So, the total arrangement of the 8 balls is:
The individual probability of each ball, when put together is
Lastly:
Answer: $35.75
Step-by-step explanation:
1) $25 for the manicure
2) $25*(0.20) = $5 for the tip
3) $5.75 for the tip
$25 + $5 + $5.75 for the total
$35.75 total

Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
Answer:
angle 3 = angle 6
angle 1 = angle 5
angle 2 + angle 5 + angle 6 = 180°
