You can use right triangles and congruence. So if the distance from Home to First is x, then the distance from Home to Third is also x because the two triangles are congruent.
2x-12=34 is the equation.
x=23
Explanation: "Twelve decreased" means that the number 12 is taken away from a certain amount. This certain amount is "twice a number" which means double a value. This value is the number that we do not know, so I used 'x' as a variable placeholder for this number. This is how I got the equation.
I then solved the equation using algebra to find the value of x. You begin this process by adding 12 to 34, which equals 46. I then divided this number by 2, which equals 12. This is the most simplified the equation can get, so 12 is the value number we are looking for.
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
