You are diagnosed with a rare disease. you know that there only is a 1% chance of getting it. use the letter d for the event "you have the disease" and t for "the test says so". it is known that the test is imperfect: p(t|d) = 0.98 and p(tc|dc) = 0.95. (a) given that you test positive, what is the probability that you really have the disease? (b) a week later you obtain a second opinion, repeating the test with a different doctor. use the letter s for the event "the second test says you have the disease". you test positive again. given this, what is the probability that you really have the disease? (c) calculate p(s|t) and compare with p(s). are s and t independent? explain.

5/12, or 5: 12

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
