A physical examination was used to screen for breast cancer in 7600 women with biopsy proven adenocarcinoma of the breast and in 11,000 age and race matched control women. The results of the physical examination were positive (i.e. a mass was palpated) in 5,500 cases and 1,700 control women (who showed no evidence of cancer at biopsy). The total population is 18,600. The sensitivity of the physical examination was:______.
Answer:
72.37%
Step-by-step explanation:
Calculation for what The sensitivity of the physical examination was
Using this formula
Sensitivity=Positive physical examination cases/Physical examination screening for breast cancer
Let plug in the formula
Sensitivity=5,500 cases / 7600 women
Sensitivity=0.7237*100
Sensitivity=72.37%
Therefore The sensitivity of the physical examination was 72.37%
Answer:
72.37% is the answer for this

GIVING BRAINIEST!!!!!!What is the equation of the line that passes through 6,4 and 2,10
Answer:
y = -3/2x + 13
Step-by-step explanation:
(6,4) and (2,10)
Slope:
m=(y2-y1)/(x2-x1)
m=(10-4)/(2-6)
m=6/(-4)
m = -3/2
Point-slope intercept:
y - y1 = m(x - x1)
y - 4 = -3/2(x - 6)
y - 4 = -3/2x + 9
y = -3/2x + 13

If DB = 18cm and AC = 24cm, Use the properties of rhombus to find the length of one side of the rhombus please helppp!!!!
Answer:
15 cm
Step-by-step explanation:
You need to remember 2 theorems about a rhombus.
1. The diagonals of a rhombus bisect each other
2. The diagonals of a rhombus are perpendicular to each other
In other words, the diagonals of a rhombus are perpendicular bisectors.
BE = 9 and AE = 12
ΔAEB is a right triangle. So, the Pythagorean theorem says
[tex]9^{2} + 12^{2} = AB^{2}[/tex]
[tex]AB^{2}[/tex] = 81 + 144
= 225
AB = [tex]\sqrt{225} = 15[/tex] cm
Turner’s backyard deck cost $38.31 per square meter to build. The deck is 9 meters wide and 11 meters long. How much did it cost to build the deck?
Answer:
$3792.69
Step-by-step explanation:
First, we would find the area,
Area = width x length
Area = 9 x 11
Area = 99[tex]m^{2}[/tex]
Since each square meter costs $38.31, we would multiply the cost with the area,
Total Cost = 99 x 38.31
Total Cost = $3792.69
(Anyone can correct me if I'm wrong)

Answer:
814.15 ft long
Step-by-step explanation:
We use the sine of 32.8 degrees to find the hypotenuse which is the length of the highway:
sine = opp/hyp
sin32.8=800/x (evaluate sin and multiply by x)
0.9826178774x = 800 (divide)
x=814.15 ft long
answer =814.15
explanation= we'll firstly need to find the hypotenuse by using the 32.8 degrees
•°• Sin 32.8=800/?
then, 0,9826178874=800
then we divide as the answer will be 814.15

What is the volume of the cone to the nearest cubic millimeter (use pi)
Find the surface area and volume of the prism
Answer:
I only know the first one.
The surface area of the prism is 900 cm2
Step-by-step explanation:
To solve the surface area, we need to find the area of the SURFACE not the inside of the cube. Lets do the rectangles first.
28 x 13 = 364
28 x 5 = 140
28 x 12 = 336
1 1
336
+ 140
364
-------------
8 4 0
Now lets do the triangles.
Remember! To find the area of a triangle, you have to do Base x Height x 1/2 because it's half a rectangle.
(The triangles have the same area)
12 x 5 x 1/2 = 30
12 x 5 x 1/2 = 30
30
+ 30
--------
60
The last step is to add the areas of the triangles and the rectangles.
1
840
+ 60
------------
900 cm2
The answer is 900cm2
This Is not copy pasted, I actually put in all this effort.

Joe and Nancy decide to take a road trip. The first 72 miles of the drive are pretty easy, while the last 84 miles of the drive are filled with curves. They drove at an average 7 miles per hour faster for the first 72 miles of the trip. The entire trip took 3 hours. How fast were Joe and Nancy driving for the first 72 miles of the trip?
Answer:
120
Step-by-step explanation:
let r be the rate for the slower, 84 miles, portion of the trip
let t1 be the time for the 120 miles portion of the trip and t2 for the 84 miles portion
:
1) t1 + t2 = 3
2) (r+9)*t1 = 120 and r*t2 = 84
3) (r+9)*t1 + r*t2 = 120 + 84 = 204
:
expand the left side of equation 3
:
r*t1 + 9*t1 + r*t2 = 204
r*(t1+t2) +9*t1 = 204
:
substitute for (t1+t2) by using equation 1)
:
3*r + 9*t1 = 204
:
divide both sides of = by 3
:
4) r + 3*t1 = 68
:
use the equation for t1 from the equations defined at 2)
:
t1 = 120 / (r+9)
:
substitute for t1 in equation 4)
:
r + 3*(120/(r+9)) = 68
:
r^2 +9r +360 = 68 * (r+9)
:
r^2 -59r -252 = 0
:
(r-63)*(r+4) = 0
:
r = 63 and r = -4
:
we reject the negative value for r
:
***************************************************************************
Joe and Nancy drove 63+9 = 72 miles per hour for the first 120 miles of the trip
