After the political ad campaign, pollsters check the dictator's negatives. They test the hypothesis that the ads produced no change against the alternative that the negatives are now below 77% and find a P-value of 0.043. Which conclusion is appropriate? Explain.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

step-by-step explanation:
