Cut the square in half and use pythagorean thereom to solve for the long side of the triangle or it’s diameter.
a^2 + b^2 = c^2

8^2 + 8^2 = c^2
64 + 64 = c^2
128 = c^2 …square root both sides
c = 11.3137 (diameter)

radius is half diameter

r = 5.6569

Then you can subtract the area of a square a=bh from the area of the circle a = pi(r)^2.

a = (8)(8) the square’s area is 64.

a = pi (5.6569)^2
a = pi (32) the circle’s area is 32pi

so subtracting the area of the square from the circle is 32pi - 64.

Therefore it is the last selection 32pi - 64.

Answer:

We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

$P(A \cap B) = P(A) *P(B)$

For this case we have that:

$P(A) *P(B) = 0.01*0.02= 0.0002$

And we see that $0.0002 \neq P(A \cap B)$

So then we can conclude that the two events given are not independent and have a relationship or dependence.

Step-by-step explanation:

For this case we can define the following events:

A= In a certain computer a memory failure

B= In a certain computer a hard disk failure

We have the probability for the two events given on this case:

$P(A) = 0.01 , P(B) = 0.02$

We also know the probability that the memory and the hard drive fail simultaneously given by:

$P(A \cap B) = 0.0014$

And we want to check if the two events are independent.

We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

$P(A \cap B) = P(A) *P(B)$

For this case we have that:

$P(A) *P(B) = 0.01*0.02= 0.0002$

And we see that $0.0002 \neq P(A \cap B)$

So then we can conclude that the two events given are not independent and have a relationship or dependence.

Is it possible that the image of a point after a reflection could be the same point as the preimage?

Vera_Pavlovna [14]

Yes, it is possible. For example, let's say that point A is (0,4) and there's a reflection over the y-axis, then point A would still be (0,4).
