A new, simple test has been developed to detect a particular type of cancer. the test must be evaluated before it is put into use. a medical researcher selects a random sample of 1,000 adults and finds (by other means) that 1% have this type of cancer. each of the 1,000 adults is given the test, and it is found that the test indicates cancer in 97% of those who have it and in 2% of those who do not?

Step-by-step explanation:

Answer to A new test has been developed to detect a particular type of cancer. ... A Medical Researcher Selects A Random Sample Of 1,000 Adults And Finds ... Each Of The 1,000 Adults Is Given The New Test And It Is Found That The Test Indicates Cancer In 99% Of Those Who Have It And In 1% Of Those Who Do Not.

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
