Answer:
(a) 0.023835
(b) 0.6281
Step-by-step explanation:
(a) The chance someone from this population will test positive is given by the percentage of people who have the virus multiplied by the change of testing positive (1 - false-negative rate) added to the percentage of people who do not have the virus multiplied by the change of testing positive (false-positive rate)

(b) The probability that someone actually has the virus given that they have tested positive is determined as the probability of having the virus and testing positive divided by the probability of testing positive:

Assuming number cube has 6 sides
probablity is (desiredoutcomes)/(total possible ouctomes)
since it is 450 times
total possible outcomes=450
experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount
so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times
experimiental is the actaull one so67 out of 450 or 67/450
theoretical is 1/6 or 75/450
experimental is 67/450
Answer:
zero im pretty sure
Step-by-step explanation:
Answer:
1.1(for infinity) or 0.9
Step-by-step explanation:
it depends if you do 90/100 or 100/90
90/100 = 0.9
100/90 = 1.1(for infinity)
so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
Answer:
(any real number, 5)
Step-by-step explanation:
Well given that y=7-2 and that y=5, we do not know the value of x, therefore x could be any real number with y being 5. I'm pretty sure that answered your question. So, a example of an ordered pair that would fit this rule would be say (5,5) or (7,5)
