Answer:
The probability that an individual has this disease given that the test indicates its presence is 0.1
Step-by-step explanation:
Let A be the event which indicates Having disease
Let B be the event in which test indicates that disease presence
Now we are given that 10% of the individuals in this age group suffer from this form of arthritis
So, P(A)=0.1
We are also given that the proposed test was given to individuals with confirmed arthritics disease, and a correct test result was obtained in 85% of the cases.
P(B|A)=0.85
Now we are given that. When the test was administered to individuals of the same age group who were known to be free of the disease, 4% were reported to have the disease
So,P(B|A')=0.04
We are supposed to find the probability that an individual has this disease given that the test indicates its presence i.e. P(A|B)
So we will use Bayes theorem
Hence the probability that an individual has this disease given that the test indicates its presence is 0.1
Answer:
<h2>The answer is 3</h2>
Step-by-step explanation:
Let the number be x
The statement
twice a number is written as
2x
The sum of twice a number and seven is written as
2x + 7
The result is 13
So we have
2x + 7 = 13
Subtract 7 from both sides
That's
2x + 7 - 7 = 13 - 7
2x = 6
Divide both sides by 2
That's
We have the final answer as
<h2>x = 3</h2>
Hope this helps you
Answer:
D
Step-by-step explanation:
We need to graph both and and figure out <em>the x-value at which the graph of is LESS THAN that of the graph of .</em>
<em />
The attached picture shows the graph of in BLUE and the graph of in RED.
<em><u>We need to find x-value where the BLUE graph is "BELOW" the RED graph.</u></em> We can see that this occurs when x < 0.
Thus the correct answer is D
