Answer:
0.0392 = 3.92% probability that the test result is positive.
Step-by-step explanation:
Probability of a positive test:
95% of 1%(person has the disease)
100 - 97 = 3% of 100 - 1 = 99%(person does not have the disease).
What is the probability that the test result is positive?

0.0392 = 3.92% probability that the test result is positive.
X=25 is the answer
EXPLANATION:
Since we have here similar triangles, then 2x+2/x+3 must be equivalent of 26/14
2x+2/x+3=26/14
2x+2/x+3=13/7
7(2x+2)=13(x+3)
14x+14=13x+39
x=25
I could be wrong but is it $1.20?
Answer:
24-6x
Step-by-step explanation:
To distribute, you multiply the number outside the parenthesis by each number inside, keeping in mind the signs.
So, 6(4-x) = 6(4) - 6(x) = 24-6x
The relationship between the cost of books and pens is an illustration of linear equation.
The linear equation is (a) 
From the question, we have:
x exceeds 2 times y by 10
Rewrite as:
x exceeds 2y by 10
Exceed means plus (+)
So, we have:

Equate the above equation to 0

Hence, the required equation is (a)
