Suppose that a pregnancy test kit, while tested on women, produces 95% true positive and 90% true negative. Suppose that 7% of w

satela [25.4K]

Answer:

0.5885

Step-by-step explanation:

The possible ways for a test to be positive are:

- Woman is pregnant & true positive

- Woman is not pregnant & false positive

The probability of a positive is:

$P(+) = 0.07*0.95+(1-0.07)*(1-0.95)\\P(+)=0.113$

Therefore, the probability that a woman is actually pregnant given that she tested positive is:

$P(P|+) = \frac{0.95*0.07}{0.113}\\P(P|+) = 0.5885$

The probability is 0.5885

Write a polynomial equation of degree 2 in standard form given that one root 2 + 5i

asambeis [7]

Answer:

x^2 - 4x + 29 = 0

Step-by-step explanation:

Complex roots occur as conjugate pairs.

So the other root will be 2 - 5i.

First write the equation it in factor form:-

(x - (2 + 5i)) (x - (2 - 5i) = 0

(x - 2 - 5i)(x - 2 + 5i) = 0 Now expand:-

x^2 - 2x + 5ix - 2x + 4 - 10i - 5ix + 10i - 25i^2 = 0

x^2 -2x - 2x + 4 - 25*-1 = 0

x^2 - 4x + 29 = 0 (answer)

Please help me !!!!!

gulaghasi [49]

Answer:

11.5

Step-by-step explanation:

Put the numbers in order from smallest to largest

2,2,6,9,9,11,11,12,32,43,46,54,54,59

The median is the middle number

There are 14 numbers so the middle is between 7 and 8

2,2,6,9,9,11,11, 12,32,43,46,54,54,59

Take the average of the 7th and 8th numbers

(11+12)/2 = 11.5

The median is 11.5

How would I do this

Solnce55 [7]

Answer:

the ramp must be lowered

Step-by-step explanation:

Use the definition of the sine function to find the height of a ramp that is 8°.

Sine = Opposite/Hypotenuse

sin(8°) = height/8

height = 8×sin(8°) = 1.11

The height Nate's dad allows is 1.11 feet. At 1.5 feet, the ramp is too high.

The ramp must be lowered.

2 1/3 −1.5x=12.3<br> Solve for x

miv72 [106K]

Answer:

x=−3.533333

Step-by-step explanation:

−1.5x=12.3

Step 1: Simplify both sides of the equation.

−1.5x=12.3

7+−1.5x=12.3

−1.5x+7=12.3

Step 2: Subtract 7 from both sides.

−1.5x+7−7=12.3−7

−1.5x=5.3

Step 3: Divide both sides by -1.5.

−1.5x

−1.5

5.3

−1.5

x=−3.533333
