Answer:
The person in the at-risk population is much more likely to actually have the disease
Step-by-step explanation:
The probability of a randomly selected doctor having the disease is 1 in 1,000 (P(I)=0.0001).
The probability that a doctor is infected with SARS, given that they tested positive is:
The probability of a randomly selected person from the at-risk population having the disease is 20 in 100 (P(I)=0.20).
The probability that a person in the at-risk population is infected with SARS, given that they tested positive is:
Therefore, the person in the at-risk population is much more likely to actually have the disease
Answer:
9/2
Step-by-step explanation:
the number of the equation is 9/2 so the answer must be 9/2
Since length • width = area you need to put the expression with “x” in (parenthesis) and put the number without a variable outside the parenthesis ex: d. would be 5(8-3x) because you would do what’s in the parenthesis first. In this case length is in the parentheses you would have 5(your answer) which means 5•your answer

Answer:
30
Step-by-step explanation:
let number of questions in the test be x
9 of the first 10 questions are correct
so only x-10 questions remain
3/10 of the (x-10) = 3/10(x-10) questions are correct
scored 50% for the whole test
so only half of x = x/2 questions are correct
combining the above:
9+3/10(x-10) = x/2
9+3/10x-3=x/2
9-3=(1/2-3/10)x
1/5x=6
x=30
