    Alfred draws candles randomly from a pack containing 4 colored candles of the same shape and size. There are 2 red candles, 1 green candle, and 1 blue candle. He draws 1 candle and then draws another candle without replacing the first one. Find the probability of picking 1 red candle followed by another red candle, and show the equation used. The probability of picking 1 red candle followed by another red candle is 1/12. 1/4 times 1/3 = 1/12

    I think that the requested probability is given by the multiplication of those probability, namely 1/2 * 1/3 = 1/6

    `There are 2 red candles, 1 green candle, and 1 blue candle` 2+1+1 = 4 candles total -------------------------- The probability of picking one red candle is (# of red)/(# total) = 2/4 = 1/2 After that first one is picked, there is 1 red candle left out of 3 candles total so the probability of picking another red candle is (# of red left)/(# total left) = 1/3 -------------------------- So that's how harryhart got his numbers and why the answer is (1/2)*(1/3) = 1/6

    A bag has 1 red marble, 4 blue marbles, and 3 green marbles. Peter draws a marble randomly from the bag, replaces it, and then draws another marble randomly. What is the probability of drawing 2 blue marbles in a row? Explain your answer. @jim_thompson5910

    The probability of drawing 2 blue marbles in a row is 1/64. 1/8 times 1/8 = 1/64. @jim_thompson5910

    Hint: there are 4 blue marbles out of 4+3+1 = 8 marbles total. The probability of drawing one blue marble is 4/8 = 1/2. Use this to figure out the probability of drawing 2 blue marbles.

    Greg has 4 shirts: a white one, a black one, a red one, and a blue one. He also has two pairs of pants, one blue and one tan. What is the probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants? Show your work. my answer: The probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 1/8. 1/4 times 1/2 = 1/8 1/4=probability of picking a white shirt 1/2 = probability of picking tan pants

    Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table (function 1) shows the relationship between the amount of money (y) remaining in Galvin’s money box and the number of months (x): Number of Months (x) Amount Remaining (in $) (y) 1 80 2 75 3 70 4 65 The equation (function 2) shows the relationship between the amount of money, y, remaining in Henry’s money box and the number of months, x: Function 2 y = −7x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month. Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month. Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month. Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends −$7 each month. i think it is A @jim_thompson5910

    A is correct. The slope of function 1 is -5 which means he spends $5 a month. The slope of function 2 is -7 meaning that he spends $7 a month

    What about: Luke buys a certain brand of cereal that costs $11 per box. Luke changes to a super-saving brand of the same size. The equation shows the price, y, as a function of the number of boxes, x, for the new brand. y = 9x Part A: How many more dollars is the price of a box of Luke’s original brand of cereal than the price of a box of the super-saving brand? Show your work. Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work. im gonna do it and post what i get for my answer. can u solve now and check my answer when i post?

    Part A: Luke's original brand of cereal costs $2 more than the price of the super-saving brand. original brand: y = 11x super-saving brand: y = 9x 11x - 9x = 2x 2x = amount saved per box Part B: Luke saves $12 each month with the change in cereal brand if he buys 6 cereal boxes each month because: $2x times 6 boxes = $12 saved $2x = money saved per box 6 = boxes bought per month

    you don't need the 2x in part A. They just want the price difference for one box. Although, you can use that equation and plug in x = 1

    well again, part A was for one box only so if it were me, i'd say 11 - 9 to keep it simple

    but you can go with 11x - 9x = 2x and plug in x = 1. It's the same idea just more work
