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.

Find the length of B to the nearest tenth using the Pythagorean theorem.

fgiga [73]

The answer is 11.2

The Pythagorean Theorem says
a^2+b^2=c^2

From the picture, we know one side, and the hypotenuse.

10^2+b^2=15^2
100+b^2=225
b^2=225
Sqrtb^2=sqrt225
b=11.18

Rounded to the nearest tenth it is 11.2

grigory [225]

Answer:

Step-by-step explanation:

use Pythagoras theorem

a^2 + b^2 = c^2

18^2+b^2=30^2

b^2 = 30^2 - 18^2

b = √576 =24
