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).

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]

[tex] RC = 40 [/tex]

(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.

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.

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.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

We have been given that ∆LMC ≅ ∆BJK.

The image of the triangles are attached below;

The triangle are congruent to each other so,

∆LMC ≅ ∆BJK

∆LM ≅ ∆BJ

∆LC ≅ ∆BK

∆MC ≅ ∆JK

Answer:

slope is 6/1 (or 6)

Step-by-step explanation:

your y-intercept is 3, so that means the point will be (0,3).

from there, you can start plotting points. up 6, over 1 (to the right)

the equation for a line is y=mx+b, so whatever number is in m will always be your slope, and whatever number is in b will be your y intercept

(4x6)^3

(24)^3=13,824

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.
