Yesterday, Tiana's Snack Shack went through 1/4 of a bottle of ketchup. If they used 2 5/6 times as much mustard as ketchup, how many bottles of mustard did they go through? Write your answer as a mixed number.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

i think the correct option is the second option.

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
