Consider Derek's example of a disease that affects one person in a thousand. The test was 99% accurate, meaning one false positive for every hundred people, or 10 in a thousand. So 11 people would get positive tests but only 1 is real. So the odds of being the real one are 1:11 or 9%. Suppose there is a new test that is 99.9% accurate; ten times more accurate. Compared to the first test, a positive result on the second test would indicate that the probability that you have the disease is

unless if u could do my questions, if not i wouldn't want to

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
