Arecent nationwide study investigated the value of the prostate-specific antigen (psa) blood test for the detection of prostate cancer among 100,000 men 50 years of age and older. of the 686 men who tested positive on the psa test, a total of 281 were ultimately diagnosed with prostate cancer, either by immediate needle biopsy or during 12 months of watchful waiting. an additional 45 men who tested negative on the psa test were ultimately diagnosed with prostate cancer during 12 months of follow-up. a screening test is available to identify individuals with a genetic mutation that puts them at greater risk for stroke. the test is extremely expensive and is not covered by most insurance plans, so those choosing to have the test usually have to pay for it out-of-pocket. however, it has been determined that the screening test is very valuable because the annual incidence of stroke among those who have been screened is nearly half that of the general population

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
