An analysis of over 160 empirical studies conducted by Norris and her colleagues (2006) revealed evidence of severe to very severe impairment (interference with functioning) among survivors. What percent of survivors were incapacitated?

.25

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

i think it might be a but you might want a second opinion
