The weights of bags of pet food are distributed normally about the mean, 50 lb. the standard deviation is 0.2 lb. in a group of 20 bags, about how many would you expect to be within one standard deviation of the mean?

figure c

step-by-step explanation:

hope this .

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
