If we are told that the margin of error is 12, the length of the confidence interval is
Your

right

step-by-step explanation:

answer: can you give the

step-by-step explanation:

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.

yes i do see that. i say this because i am doing my very best in high school so i can get a scholarship and credits.
