Answer:
Step-by-step explanation:
Given
Probability of finding oil at site 1 is 0.30
Probability of finding oil at site 2 is 0.15
Probability of finding oil at site 3 is 0.20
Probability of Finding oil at all three sites
i.e. oil is present in all three sites simultaneously

Probability of not finding oil at any of these sites
Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites
i.e.
Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

That’s false because two lines are to short so it’s false
This does not need the quadratic formula since there are no variables to begin with:
62-46+4 = 0
20 = 0.
And 20 does not equal 0 so both sides aren't equal.
Soooo not much to do with this question.
Answer:You haven't attached a picture but this is what your line should look like
Step-by-step explanation:
For this equation you simply have to graph it.
First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.
Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.
Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.
Hope this helps a bit,
