The probability that a person has a certain disease is 0.03. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually present, the probability that the medical diagnostic test will give a positive result (indicating that the disease is present) is 0.92. Of the disease is not actually present, the probability of a positive test result (indicating that the disease is present) is 0.01. a. If the medical diagnostic test has given a positive result (indicating that the disease is present), what is the probability that the disease is actually present
Answers
Answer: 0.74
Step-by-step explanation:
A= "The person is sick"
B= "The test gives a positive result"
P(A)=0.03
P(B|A)=0.92
P(B|A')=0.01
P(A')=1-P(A)=1-0.03=0.97
P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373
Based in Bayes Rule
P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74

Answer:
16x^3 +64x^2 -40x
Step-by-step explanation:
Use the distributive property. The factor outside parentheses multiplies each term inside parentheses:
8x(2x^2 +8x -5) = (8x)(2x^2) +(8x)(8x) +(8x)(-5)
= 16x^3 +64x^2 -40x

Answers
The design that every point on one side of the line coincides with a point on the other side of it is Line of symmetry
What is Symmetry?
Symmetry in mathematics means that when one shape is moved, rotated, or flipped, it looks exactly like the other shape.
A circle or band that divides a body's surface into two typically equal and symmetrical portions.
When a shape or item has a centralpoint, point symmetry occurs when all points on the opposing sides are at the same distance from the centre.
The term "line of symmetry" refers to the fictitious axis or line that can be used to fold a figure into symmetricalhalves.
It denotes that one half is the other half's mirror image.
Thus, the required design is Line of Symmetry.

Answer:
7 meter = 0.007 kilometer .
Step-by-step explanation:
Given : A meter is one thousandth of a kilometer.
To find : Write an equation to show the relationship between 7 meters and 0.007 kilometer.
Solution : We have given
1 meter = kilometer .
7 meter = kilometer.
We can write the 0.007 kilometer = kilometer.
We can say 7 meter = 0.007 kilometer .
Therefore, 7 meter = 0.007 kilometer .

Answer:
- A = 1.5
- B = -1/3
- C = -4/3
Step-by-step explanation:
For A:
- A is smack in the middle of 1 and 2, so it it 1 1/2 or 1.5 (same thing)
For B:
- Each tick mark between the numbers represents 1/3
- B is on the first tick mark between 0 and -1, so therefore it is -1/3
For C:
- C is on the first tick mark between -1 and -2
- That means C is -1 1/3
- -1 1/3 = -4/3
