A test to determine whether a certain antibody is present is 99.1% effective. This means that the test will accurately come bac

avanturin [10]

Answer:

The probability that all the six people will test negative for the antibody is 0.9472.

The probability that the test comes back positive for at least one of the six people is 0.0528

Step-by-step explanation:

Consider the provided information.

probability that antibody is present will be effective is 99.1% and not present is 99.1% of the time.

Part (A)What is the probability that the test comes back negative for all six people? 

Let P(X)= P(Antibody not present)

We want test comes back negative for all six that means antibody is present for all six. Thus X=0

$P(X=0)=0.991\times0.991\times0.991\times0.991\times0.991\times0.991\\P(X=0)=0.9472$

The probability that all the six people will test negative for the antibody is 0.9472.

Part (B) What is the probability that the test comes back positive for at least one of the six people?

$P(X \geq1)=1-P(X=0)$

$P(X \geq1) = 1-0.9472$

$P(X \geq1) = 0.0528$

Hence, the probability that the test comes back positive for at least one of the six people is 0.0528

NEED THIS DONE ASAP!! Thank you!!

Answer:

$\overset{\frown}{WX}= 66^{\circ}$

Step-by-step explanation:

Inscribed Angle Theorem

The measure of an inscribed angle is half the measure of the intercepted arc.

First, use the Inscribed Angle Theorem to calculate the measure of arc WY.

$\displaystyle \angle WXY=\dfrac{1}{2} \overset{\frown}{WY}$

$\implies 57^{\circ}=\dfrac{1}{2} \overset{\frown}{WY}$

$\implies \overset{\frown}{WY}= 2 \cdot 57^{\circ}$

$\implies \overset{\frown}{WY}= 114^{\circ}$

Assuming XY is the diameter of the circle:

$\implies \overset{\frown}{WY}+ \overset{\frown}{WX}= 180^{\circ}$

$\implies 114^{\circ} + \overset{\frown}{WX}= 180^{\circ}$

$\implies \overset{\frown}{WX}= 180^{\circ} - 114^{\circ}$

$\implies \overset{\frown}{WX}= 66^{\circ}$

2.943÷2.7 show ur work plzz

Yanka [14]

Answer:

1.09

Step-by-step explanation:

I *really* wish I had work to show, but I just used a calculator as it is a simple division problem. Since you can do long divison, here are the steps! It is very hard to show on here, so I have typed it out:

Step 1: Estimate the answer by rounding. You'll use this estimate to check your answer later.

Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number. Then move the decimal place in the dividend the same number of places to the right (adding some extra zeros if necessary.)

Step 3: Divide as usual. If the divisor doesn't go in evenly, add zeros to the right of the dividend and keep dividing until you get a 0 remainder, or until a repeating pattern shows up.

Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.

Step 5: Check your answer against your estimate to see if it's reasonable.
