Researchers have discovered a new genetic marker for a form of cancer. Twelve percent of the overall population carry this marke
In-s [12.5K]

Answer:

The probability that a person with the marker develops cancer is 0.0725.

Step-by-step explanation:

Let's denote the events as follows:

<em>A</em> = a person has cancer

<em>B</em> = a person carries the marker.

<u>Given:</u>

P (A) = 0.03

P (B) = 0.12

P (B|A) = 0.29

The conditional probability of an event <em>X</em> provided that another event <em>Y</em> has already occurred is:

P(X|Y)=\frac{P(Y|X)P(X)}{P(Y)}

Use the conditional probability formula to compute the probability that a person with the marker develops cancer.

P(A|B)=\frac{P(B|A)P(A)}{P(B)} =\frac{0.29\times0.03}{0.12}=0.0725

Thus, the probability that a person with the marker develops cancer is 0.0725.

What is the slope of the line whose equation is 5y + 6x - 2 = 0
koban [17]
All you need to do to find the slope here is put it into y = mx + b format.

5y + 6x - 2 = 0

the goal is to get the y alone, so...

5y = 2 - 6x

divide both sides by 5

y = 2/5 - (6/5)x

then, just to be clearer for y = mx + b ...... y = (-6/5)x + (2/5)

the slope should be (-6/5)

Sever21 [200]
Distance = speed X time

distance in heavy traffic = 40mph X 1hour = 40miles

distance in light traffic = 60mph X 3hours = 180miles

Total distance = 180 + 40 = 220miles
