The <em>correct answer</em> is:
D) Rotated perpendicular lines always remain perpendicular lines.
Explanation:
Perpendicular lines, by definition, meet at a 90° angle.
As long as both lines are rotated the same direction and the same angle, then the angle between the two lines will not change. They will continue to be perpendicular, no matter how many degrees or which direction they are rotated.

Answer:
8% probability that he or she actually has the disease
Step-by-step explanation:
We use the Bayes Theorem to solve this question.
Bayes Theorem:
Two events, A and B.

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
If a randomly chosen person is given the test and the test comes back positive for conditionitis, what is the probability that he or she actually has the disease?
This means that:
Event A: Test comes back positive.
Event B: Having the disease.
Test coming back positive:
2% have the disease(meaning that P(B) = 0.02), and for those, the test comes positive 98% of the time. This means that 
For the 100-2 = 98% who do not have the disease, the test comes back positive 100-77 = 23% of the time.
Then

Finally:

8% probability that he or she actually has the disease
Answer:
174 I'm pretty sure
Step-by-step explanation:
multiply 9 x10 = 90
subtract 90 - 3=87
multiply 87×2
