whether the distribution of a RV x-bar can be assumed to be approximately normal.

whether the distribution of a RV x-bar satisfies the criterion of independence.

whether the distribution of a RV p-hat can be assumed to be approximately normal.

whether the distribution of a RV p-hat satisfies the criterion of independence.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: x=3 and y=4
