recent random survey of 1,000 Americans asked them what they would do with an unexpected tax return. 470 of them indicated they would use it to pay down debt. Calculate a 90% confidence interval for the proportion of all people who would use an unexpected tax refund to pay debt. 1. Calculate p-tilde, the initial estimate for the proportion of people who would pay down debt. Use five decimals for accuracy. 470/1000=0.47000 (471)/(1002)=0.47006 (472)/(1004)=0.47012

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

f(y)= y^2-10y+25

answer is d. (5, 3); 8. hope you got it down bud.
