Let's think of an example which would better help visualize this situation.
1) Someone exercises a lot so they can concentrate more on their homework (here running and concentration on homework are dependent events)
2) Someone exercises a lot because they wear a blue t-shirt (here, you can clearly see that wearing a blue shirt and exercising are not related. These events are independent).
Now concentrating on P(a | b) = Probability a occurred if b occurred.
It does not matter if b occurred (just like it didn't matter that the person wore a blue shirt which meant that they exercised) for the outcome a to occur.
Therefore, probability of P(a | b) = P(a)
P(a | b) = 0.65
Hope I helped :)
Answer:
9 and -9
Step-by-step explanation:
Answer:
Half of 12 is 6(new radius)
6^2 = 36
36 x 3.14 = 113.04
113.04 x 8 = 904.32
904.32 divided by 3 ( x 1/3) = 301.44 m is your answer.
Answer:
It could be anything...
Step-by-step explanation:
Unfortunately, you did not provide us with enough information to solve this question. Try adding the Multiple choice if there is one?
We have to find the lengths of the sides XY and XW:
XY² = ( - 7 - ( - 4 ) )² + ( - 1 - 0 )²
XY² = ( - 7 + 4 )² + ( - 1 )²
XY² = 9 + 1 = 10
XY = √10
XW² = ( - 6 - ( - 4 ))² + ( 6 - 0 )²
XW² = ( - 6 + 4 )² + 6 ²
XW² = 4 + 36 = 40
XW = √ 40 = 2 √10
The perimeter of the rectangle:
P = 2 · √10 + 2 · 2√10 = 2√10 + 4√10 = 6√10
Answer:
C ) 6√10 units.
