Answer:
(Prfail)=(1−Prpass)=(1−(−2)2(+)2)
Step-by-step explanation:
If is the width of a mesh hole, then (12++12)=(+) is the distance from one wire midpoint to the midpoint of the wire on the opposite side of the hole. If is the number of holes, then the total area of the mesh is
=(+)2
In order to pass through the hole without touching a wire, the center of the spherical particle needs to be positioned within a smaller square that has the side (−2). The total area that allows pass-through is therefore
=(−2)2
For a single drop, the probability of passing through is
r==(−2)2(+)2
And the probability of failing(Prfail) = 1 - Prpass
Assuming each drop is an independent event, the probability of failing drops is
(Prfail)=(1−Prpass)=(1−(−2)2(+)2)
We can set up the following equation:
4x + 4(5) = 54
X representa the cost of a salad, and the 4(5) shows how each time she left a tip of 5.
Now we solve:
4x + 20 = 54
Subtract 20 from each side:
4x = 34
Now divide by 4
X = 8.5
So the cost of each salad is $8.50
I hope this Helps!
Try scanning it on the camera maybe brainly knows how to answer this?
Answer:
x=15
Step-by-step explanation:
-3x+33=-12
-3x=-12-33
-3x=-45
x=-45/-3
x=45/3
x=15
