Answer:
2. Perimeter = 98 cm, área = 588 cm²
Answer:
x = 15/11
Step-by-step explanation:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
(x+3) *x = 2x*(6x-6)
Divide each side by x
x+3 = 2(6x-6)
Distribute
x+3 = 12x-12
Subtract x from each side
x+3-x = 12x-x-12
3 = 11x-12
Add 12 to each side
3+12 = 11x-12+12
15 = 11x
Divide each side by 11
15/11 =x
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:

For this case we have that:

And we see that 
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:

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

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:

For this case we have that:

And we see that 
So then we can conclude that the two events given are not independent and have a relationship or dependence.
The answer is 20 because 3 is closer t 1 than 10
