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

Answer:
The answer is 15
Step-by-step explanation:
its 15 because unit rate is like 60 min=1 hour
and in this situation, the unit rate would be 15 because for every hour he earns 15 dollars
Subtract the two prices to find the difference, then divide the difference by the original price
.
880 - 640 = 240
240 / 880 =0. 2727 = 27.27% discount Round the answer as needed.
The points on the line are points B and D
<h3>How to determine the points on the line?</h3>
The equation is given as:
y = x + 4
The above means that the output value is 4 more than the input value
Using the above rule, the points that satisfy the equation are:
B) 2, 6 and D) 2, 4
This is so because:
6 = 2 + 4
4 = 2 + 2
Hence, the points on the line are points B and D

There are no statements on your list that describe the roots.
If the discriminant is a negative number, then the two roots
of the equation are complex conjugates. They both have
imaginary parts to them.
