Answer:
it's the third one 3
Step-by-step explanation:
78, a constant represents the initial temperature
Domain- {-2, 1, 0, 1, 2}
Range- {-2, 0, 2}
My domain is right but I don’t think my range is. I did learn this 4 years ago though so
For lines to be perpendicular they would need to have opposite slopes, so for a slope of -3/7 the slope of a perpendicular line would be 7/3
Answer:
the probability is 9/71 ( 12.67%)
Step-by-step explanation:
defining the event Te= the test indicates tuberculosis , then the probability is:
P(Te)= probability of choosing a subject that has tuberculosis * probability that the test indicates tuberculosis given that a subject with tuberculosis was chosen + probability of choosing a subject that has not tuberculosis * probability that the test indicates tuberculosis given that a subject that has not tuberculosis was chosen = 8/1000 * 90/100 + 992/1000 * 5/100 = 0.0568
After this, we can use the theorem of Bayes for conditional probability. Then defining the event Tu= choosing a subject that has tuberculosis, we have
P(Tu/Te)= P(Tu∩Te)/P(Te) = 8/1000 * 90/100 / 0.0568 = 9/71 ( 12.67%)
where
P(Tu∩Te) = probability that a subject with tuberculosis is chosen and the test indicates tuberculosis
P(Tu/Te)= probability that a subject with tuberculosis was chosen given that the test indicates tuberculosis
Its 27 all you do is
81 x1
3x27
135x1
5x27
which leads to =27
