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.
7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula 
(7-3)^2+(8-2)^2
(4)^2+(6)^2

Answer:
a(10 - 13)
Step-by-step explanation:
The only common factor between these numbers is a, as 10 and 13 do not share factors (13 is prime). We can only factor out a.
Answer:

Step-by-step explanation:
5x6x3 and 5x18 equal 90
There are some missing details in the question. I found a similar question with some addition of details as follows:
The Sugar Sprinkles package contained 3/4 of a cup of the mix that needs to be mixed with 2 2/5 cups of flour, 2 1/4 cups of brown sugar, 3 3/8 and cups of water. The directions indicate to use 0.1125 of a cup of dough to make one cookie and 1 batch should make a total of Sugar Sprinkles cookies.
The Chocolate Turtle package contained 0.875 of a cup of the mix that needs to be mixed with 3.25 cups of flour, 2.5 cups of brown sugar, and 3.75 cups of water. The directions indicate to use 1/8 of a cup of dough to make one cookie and 1 batch should make a total of Chocolate Turtle cookies. The difference in the number of cookies of each type is _____
Answer:
Difference in number of cookies is 1
Step-by-step explanation:
This question is quite a tricky one. You have to be careful when answering it.
For sugar sprinklers, it contains 3/4 of a cup of the dough. For every 0.1125 of a cup, 1 cookie can be made.
So, 3/4 ÷ 0.1125
= 0.75 ÷ 0.1125
= 6.66667
Hence the most can be made is 6.
Note that we do not use the other volume because 0.1125 cup of a dough is the amount of cup from the original mix
The same applies to chocolate turtle cookies. It contains 0.875 of a cup. For every 1/8 of a cup can make 1 cookie.
0.875 ÷ 1/8 = 7
So the difference in the number of cookies is 7 - 6 = 1
