The prostate-specific antigen (PSA) test is a simple blood test to screen for prostate cancer. It has been used in men over 50 as a routine part of a physical exam, with levels above 4 ng/mL indicating possible prostate cancer. The test result is not always correct, sometimes indicating prostate cancer when it is not present and often missing prostate cancer that is present. Suppose that these are the approximate conditional probabilities of a positive (above 4 ng/ml) and negative test result given cancer is present or absent. In a large study of prostate cancer screening, it was found that about 6.2% of the population has prostate cancer. Draw a tree diagram for selecting a person from this population (outcomes: cancer present or absent) and testing his blood (outcomes: test positive or negative).

Answers

Answer 1

The missing table for the Test Result can be expressed as:

                              Test Result

                               Positive         Negative

Cancer Present        0.21              0.79

Cancer Absent        0.06              0.94

Answer:

Step-by-step explanation:

A tree diagram is an elegant way of determining an exhaustive list of sample elements in the sample space. It is by finding the ordered n-tuples of the elements in the events under consideration.

The tree diagram for selecting a person from the population in the given question can be found in the attached image below.

which number makes the number sentence true? (6+9)+4=4+?

Answers

Answer

(6+9)+4=4+15

Step-by-step explanation:

First you would do (6+9) because it's in parenthesis. (6+9)= 15. So now our equation looks like 15+4=4+? Next we will do 15+4=19. 19=4+? is the new equation. Now the final step is to do 19-4=15 which is what we will plug into the equation.

Meandre has 8 pints of milk. If he drinks ¼ of a pint of milk each day, how long will the 8 pints of milk last him?

Answers

Answer:

16 days

Step-by-step explanation:

1/4 = 0.25

8 divied 32

In multiplacation

8 time 4 = 32

8 pints of milk will last for 32 days.

What is Division?

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given that,

Total amount of milk Meandre has = 8 pints

Amount of milk drinking in 1 day = 1/4 pint

We have to calculate the number of days that 8 pints of milk will last.

Let x be the required number of days.

Using the concept of proportion,

(1/4) / 1 = 8 / x

1/4 = 8 / x

x = 8 × 4

x = 32

Hence total number of days that 8 pints of milk will last is 32 days.

when you multiply 4^3 with 6^3 you get the same answer of 13,824

Answer:

Answer=D

Step-by-step explanation:

(for powers outside a bracket it splits in the numbers inside the bracket)

(4×6)^3

=([tex]4^{3}[/tex]×[tex]6^{3}[/tex]) as in D

To proof

-if we multiply them first we will get 24 and that to the power of three will equal to 13824.

-if we did as in the answer so,

[tex]4^{3}[/tex]×[tex]6^{3}[/tex]

=64×216

=13824

they are equal to each other 13824=13824 so answer D is correct.

C is the circumcenter of PQR
PC=3x+7, RC=5x-15 and QC=51-x.
what does RC equal?

Answers

Answer:

[tex] RC = 40 [/tex]

Step-by-step explanation:

Given:

PC = 3x + 7,

RC = 5x - 15,

QC = 51 - x.

Required:

measure of RC

SOLUTION:

Given that C is the circumcenter of ∆PQR, therefore, vertices P, Q, and R are equidistant from C.

So therefore,

[tex] PC = RC = QC [/tex]

Let's find the value of x using:

[tex] PC = RC [/tex]

[tex] 3x + 7 = 5x - 15 [/tex] (substitution)

Collect like terms

[tex] 3x - 5x = -7 - 15 [/tex]

[tex] -2x = -22 [/tex]

Divide both sides by -2

[tex] x = \frac{-22}{-2} [/tex]

[tex] x = 11 [/tex]

Find the measure of RC

[tex] RC = 5x - 15 [/tex]

substitute x = 11 into the equation

[tex] RC = 5(11) - 15 [/tex]

[tex] RC = 55 - 15 [/tex]
