Answer:

option A, D and F are correct.

|x| = 9,  -|-x| = –9 and |–x| = 9

Step-by-step explanation:

Absolute value of any number is positive or 0.

for example:

|-a| = a

|a| = a

As per the statement :

For which equations is x = 9 a possible solution.

Option A:

|x| = 9

by definition of absolute value:

⇒x = 9

Similarly,

Option B:

-|x| = 9

⇒ -x = 9 or x = -9

Option C

-|-x| = 9

⇒ -x = 9

⇒x = -9

Option D:

-|-x| = –9

⇒ -x = -9

⇒ x = 9

Option E

|x| = –9

⇒x = -9

Option F

|–x| = 9

⇒x =9

Option G

|–x| = –9

⇒x = -9

Therefore, an equation for which possible solution is x = 9 are:

|x| = 9,  -|-x| = –9 and |–x| = 9.

Answer:

The probability that the result is positive is P=0.04475=4.475%.

Step-by-step explanation:

We have the events:

D: disease present

ND: disease not present

P: test positive

F: test false

Then, the information we have is:

P(D)=0.005

P(P | D)=0.99

P(P | ND)=0.04

The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).

P(P)=P(P | D)*P(D)+P(P | ND)*(1-P(D))\\\\P(P)=0.99*0.005+0.04*0.995\\\\P(P)=0.00495+0.0398=0.04475

The probability that the result is positive is P=0.04475.
