Day of the WeekIce Cream Cones Sold Monday45 Tuesday41 Wednesday33 Thursday39 Friday49 A local ice cream store kept track of how many cones it sold during a five day period last week and the data is shown in the chart above. This is the range of the ice cream cones sold.
What is 16 ice cream cones? Explanation: Range is the difference between the highest number and lowest number in a set of data. The highest number of the data is 49 and the lowest number is 33, so the range is 16.
Day of the WeekIce Cream Cones Sold Monday45 Tuesday41 Wednesday33 Thursday39 Friday49 A local ice cream store kept track of how many cones it sold during a five day period last week and the data is shown in the chart above. This is the median number of ice cream cones sold.
What is 41 ice cream cones? Explanation: Median is the number found in the middle of a set of data after the numbers have been put in order. The data in order is 33, 39, 41, 43 and 49.
The mode of five different test scores is 89. Four of the scores are 89, 93, 78, and 85. This is the fifth score.
What is 89? Explanation: Mode means the number found most often in a set of data. In order for the mode to be 89, there has to be another score of 89 in the list.
Bill’s median of 7 different scores is 87. Six of the scores are 99, 81, 90, 78, 93, and 82. This is the seventh score.
What is 87? Explanation: Median means the number found in the middle of a set of data after the numbers have been arranged in order. The 6 given numbers in order are 78, 81, 82, 90, 93, and 99. Since the median of all seven scores is 87, 87 must be the missing score.
Sally’s mean of 5 different scores is 4. Four of the scores are 3, 8, 2, and 1. This is the fifth score.
What is 6? Explanation: The mean is the average of the set of numbers. If the mean of the 5 test scores is 4, that must mean the test scores added together must be 20. (20 ÷ 5 = 4). The first four test scores add up to 14, so the fifth test score must be 6.
This is the answer to the following expression 10 – 4 x 2
Abby, Barbara, and Chris all got their math test back. Abby missed 12% of the questions, Barbara got 80% of the questions right. Chris missed ¼ of the questions. This is the person who got the best grade.
Andy has 20 marbles in a bag. 15 of them are red and the other five are black. Andy plans to take out a marble out of the bag, record its color, and then return the marble to the bag. He plans on doing this 100 times. According to theoretical probability, this is the number of times he should pull out a red marble out of the 100 times.
What is 75 times? Explanation: Fifteen out of the twenty marbles are red, which means ¾ of the marbles are red. If Andy pulls 100 marbles out of the bag, ¾ of them should be red, which is 75%.
Emily has a six sided die with the numbers 1 – 6 on each side. This is the theoretical probability, expressed as a fraction, that she will roll a 1 on her first two rolls.
What is the number 1/36? Explanation: There are 6 possible ways the die can roll on its first throw and 6 possible ways the die can roll on its second throw. To find the total number of possible outcomes, you need to multiply the number of choices for each throw together. 6 x 6 = 36 which means that if you made a tree diagram, you would have 36 possible outcomes. Only one of those outcomes on a tree diagram would be 1,1.
