10, 16, 28, 45, 55, 63, 75, 84 __________________ MEDIAN: Find the number in the middle of the set. 10, 16, 28, 45, 55, 63, 75, 84 There cannot be two medians, so you find the number between 45 & 55. MEDIAN = 50 _________________ MEAN: Find the average by adding up all of the numbers and dividing them by how many numbers there are. 10 + 16 + 28 + 45 + 55 + 63 + 75 + 84 = 376 376/8 = 47 MEAN = 47 ________________ MODE: The number that occurs most often. If no number repeats, there's no mode. THERE IS NO MODE ________________ RANGE: The difference between the largest and smallest value in the set. Subtract the largest (84) and smallest (10) value. 84 - 10 = 74 RANGE = 74
Mean: 47. Mean is when you add up all the numbers, then divide by how many numbers you added (adding them together you get 376, which you divide by 8).
Median: 50. Median is when you sort every number numerically and find which number is in the middle. Since there are 8 numbers, there are 2 numbers you'd find the number equally in between each of those 2 numbers. That number being 50.
Mode: There is no mode. Mode is the number that is "most frequent" or is repeated the most in the number sequence.
Range: 74. Range is when you subtract the smallest number of the sequence from the largest number.
The answer is C) 10x + 330 ≤ 600. We use the ≤ since you are allowed to use the 600th minute. When we subtract 330 from both sides, it makes a bit more sense 10x ≤ 270 270 is the number of minutes left your plan since you've already used 330, and you have 10 days left in the month.
