Answer:

This I am not so sure though but might be correct but what the heck xD

Step-by-step explanation:

2)

There are three points labelled

A(100,10)\ B(180,21)\ C(200,5)\\

The points whose (x , y) values represent the group reaching its fundraising goal would be B(180,21) as its on the line which means it satisfies the equation. The other points A and B are anomalies which don't lie on the line and thus don't satisfy the equation. So 180 tickets were sold during 21 hours of rental thus reaching the fundraising goal.

3)

The graph would be a solid line that represents the situation (180,21)

If it were (200,5) the line would have been dotted and the area shaded would be under the line .

If it were (100,10) the line would have been dotted and the area shaded would be above the line

Elodia [21]
This item can be solved by the probability theorem called Bayes' theorem which states that the probability of event A occurring given event B is equal to,
                            P(A/B) = P(A)P(B/A) / P(B)
where P(B/A) is the probability that the test will yield positive if the person has the disease. P(A) is the probability will be present in any particular person which is equal to 0.04. 

P(B) is the probability of positive result irrespective of whether the disease is present of not is calculated below.
                   P(B) = (0.94)x (0.04) + (0.06)(0.96) = 0.0952

Now, solving for P(A/B)
                            P(A/B) = (0.94)(0.04) / 0.0952 = 0.039
Thus, the answer is approximately 4%.
