It has been estimated, with 90% confidence, the proportion of Americans who go out shopping on Black Friday is 0.40 with a margin of error equal to 0.04. Determine the resulting 90% confidence interval for the proportion of Americans who go out shopping on Black Friday.

i am sure it will be 90 degrees.

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
