- In a bag, a child has 325 coins worth $19.50. There were three types of coins: pennies, nickels, and dimes. If the bag contained the same number of nickels as dimes, how many of each type of coin was in the bag?arrow_forwardThis game is called “Get Negative”. Roll two dice (record these in the order you roll them), and then do then do the following: take the first number rolled and subtract 2 times the second number rolled. Regardless of who rolls, Player A gets 3 points if the product is greater than or equal to 0 (i.e. it is zero or positive); Otherwise Player B gets 1 points. The players may or may not take turns rolling the dice as it does not matter who is rolling. Any player may score on any roll, and every roll will result in a score. Play the game by rolling the dice 25 times. For each turn, keep a record of both dice and the resulting answer and the points scored, according to the rules above. Tally the points and calculate the final score for each player. Remember, someone gets a point for each turn, depending on the numbers rolled. (One does not have to be rolling to receive the points.) (Note: you may test the game by yourself by doing all of the 25 rolls yourself and just giving the…arrow_forwardwhen B= 7 and K= 9arrow_forward
- Find the values of a, b, c, and d.arrow_forwardMiguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1). Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.) Xi 2 –1 P(xi) What is Miguel’s expected value from playing the game? Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays? What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation. A game at the…arrow_forwardWhat is the value of b and c?arrow_forward
- Visualize three playing cards adjacent to one another. A five is just to the right of a three, and a five is just to the left of the five. There is a heart just to the left of a diamond, and a heart just to the right of the heart. What are the three cards and their specific order from left to right?arrow_forwardIt is common to report a golfer's score on a hole in relation to par. For example, one stroke over par is a bogey and two strokes over par is a double bogey. Scores one, two, or three strokes below par are respectively a birdie, an eagle, or the extremely rare albatross. (a) Erratic Ernie scored 1 albatross, 3 eagles, 5 birdies, 7 pars, 2 bogeys, and 0 double bogeys on a par-76 eighteen-hole course. What was Ernie's score for the round?arrow_forwardPlease answer B & C.arrow_forward
- Find the answers to A, B, C, and D.arrow_forwardA box contains red, green, blue, and yellow balls. Jill randomly took a ball out of the box 55 times and recorded its color. Each time, she replaced the ball before taking out another one. The table shows the colors of the balls that Jill took out of the box.arrow_forwardIt is common to report a golfer's score on a hole in relation to par. For example, one stroke over par is a bogey and two strokes over par is a double bogey. Scores one, two, or three strokes below par are respectively a birdie, an eagle, or the extremely rare albatross. (a) Erratic Ernie scored 1 albatross, 3 eagles, 3 birdies, 7 pars, 2 bogeys, and 2 double bogeys on a par-69 eighteen-hole course. What was Ernie's score for the round? (b) In July 2013, Erratic Ernie started with 4 pars, but then shot a course record 8 straight birdies on holes 5 through 12. He followed this feat with bogeys on the next three holes and finished the round with pars. What was his final score on the par-69 course?arrow_forward
