Chris is completing his chores. He has two chores remaining: dusting and vacuuming. Chris is having trouble deciding which chore to complete first. Which of the following best describes a method of assuring that each chore has a fair chance of being selected to complete first?
A.
There is no way to assure that each chore has a fair chance of being selected to be completed first.

B.
Roll an ordinary die. If the die lands on an even number, dust first. If the die lands on an odd number, vacuum first.

C.
Flip a fair coin two times. If the coin lands on heads on both flips, dust first. If the coin lands on tails on both flips, vacuum first. If the coin lands on a heads on the first flip and tails on the second flip, vacuum first. If the coin lands on tails on the first flip and heads on the second flip, flip again.

D.
Roll an ordinary die. If the die lands on one, dust first. If the die lands on two, vacuum first. If the dies lands on three, dust first. If the die lands on four, five, or six, roll again.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
