2. Researchers suspect that 18% of all high school students smoke at least one pack of
cigarettes a day. At Wilson High School, with an enrollment of 300 students, a study
found that 50 students smoked at least one pack of cigarettes a day. At a =0.05, can
the study conclude that 18% of all high school students smoke at least one pack of
cigarettes a day?

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

this doesn't make sense lol

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 !
